The one-step synthesis of porous carbon nanoflakes possessing a 3D texture is achieved by cooking (carbonization) a mixture containing two condiments, sodium glutamate (SG) and sodium chloride, which are commonly used in kitchens. The prepared 3D porous carbons are composed of interconnected carbon nanoflakes and possess instinct heteroatom doping such as nitrogen and oxygen, which furnishes the electrochemical activity. The combination of micropores and mesopores with 3D configurations facilitates persistent and fast ion transport and shorten diffusion pathways for high-performance supercapacitor applications. Sodium glutamate carbonized at 800 °C exhibits high charge storage capacity with a specific capacitance of 320 F g(-1) in 6 m KOH at a current density of 1 A g(-1) and good stability over 10,000 cycles. © 2015 WILEY-VCH Verlag GmbH & Co.

Lotus ( Nelumbo nucifera ) root has been used as an edible vegetable in East Asia for thousands of years. The present research was aimed to explore the physicochemical, nutritional and microbiological safety of lotus root fermented sugar syrup as a fermented food supplement or condiment for human health benefits. In this study, the physicochemical, nutritional and microbiological safety properties of lotus root syrup fermented with 57° Brix brown sugar at different time periods until 6 months (180 days) was investigated. There was a significant improvement as compared to 57° Brix brown sugar broth (as a control) in the total acceptability and physicochemical properties of lotus root sugar syrup samples such as pH and color improvement. The red color values of 180 days lotus root fermented sugar syrup samples were significantly enhanced (6.85 ± 0.58) when compared with the control (0.20 ± 0.15). In addition, the total protein content was increased from 8.27 ± 0.86 to 392.33 ± 7.19 μg/mL, along with the increase in fermentation time reaching to the level of consumption acceptability. All the lotus root fermented sugar syrup samples were subjected to microbiological analysis. It was found that the coliform, Bacillus cereus , Escherichia coli , Salmonella and Staphylococcus aureus counts were not detected in majority of the samples, confirming the high degree of hygiene processing of lotus root fermented sugar syrup samples for its use as a food supplement or condiment.

The prevalence and characteristics of Escherichia coli and Salmonella spp. as well as counts of E. coli in raw oysters, condiments/spices, and raw oyster cocktails sampled from 72 vendors across Western Trinidad were determined. The microbial quality of the water used in the preparation of raw oysters was also investigated. Of 200 samples each of raw oysters, condiments/spices and oyster cocktails tested, 154 (77.0%), 89 (44.5%) and 154 (77.0%) respectively yielded E. coli. The differences were statistically significant (P = < 0.001; chi square = 62.91). The mean E. coli count per g in the ready-to-eat oyster cocktail ranged from 1.5 x 10(3) +/- 2.7 x 10(3) in Couva to 8.7x10(6) +/- 4.9x10(7) in San Fernando. One hundred and forty-six (73.0%) oyster cocktails contaminated with E. coli had counts that exceeded the recommended standard of 16 per g. Of a total of 590 E. coli isolates from various sources tested, 24 (4.1%), 20 (3.4%) and 69 (11.7%) were mucoid, haemolytic and non-sorbitol fermenters respectively. Twelve (2.0%) isolates of E. coli were O157 strains, while 92 (46.0%) of 200 E. coli isolates tested belonged to enteropathogenic serogroups. Ninety (45.0%) and 73 (36.5%) of 200 water samples contained total coliforms and faecal coliforms respectively, with counts that exceeded 2.2 coliforms per 100 ml. Salmonella spp. were isolated from 7 (3.5%), 1 (0.5%) and 2 (1.0%) of 200 samples each, of raw oysters, condiments/spices and oyster cocktails respectively. Oysters pose a health risk to consumers in Trinidad, particularly from colibacillosis and salmonellosis, and the need for increased public awareness of this hazard cannot be over-emphasized.

Lactic acid bacteria (LAB) are the predominant micro-organisms in tempoyak, a Malaysian acid-fermented condiment. In a study on the diversity of LAB in this product, three isolates could not be identified using SDS-PAGE of whole-cell proteins or API 50 CH. The taxonomic position of the three isolates was clarified in the present study. 16S rDNA sequencing classified a representative strain in the genus Lactobacillus, clearly separated from all known species, and most closely related to the Lactobacillus reuteri phylogenetic group. DNA-DNA hybridization experiments and an extensive phenotypic description confirm that the strains represent a single and separate novel species among the obligately heterofermentative lactobacilli. The three isolates are distinguished at the intra-species level by plasmid profiling, pulsed-field gel electrophoresis of macro-restriction fragments and biochemical features. The name Lactobacillus durianis sp. nov. is proposed for the novel taxon and the type strain is LMG 19193T (= CCUG 45405T).

India being a multicultural nation, every region of the country offers a distinct culinary flavor and taste. These flavors are attributed to spices and condiments which form the mainstay of Indian cuisine. Most of these spices and condiments are derived from various biodiversity hotspots in India and form the crux of India's multidiverse and multicultural cuisine. Apart from their varying aromas, flavors and tastes, these spices and condiments are known to possess several medicinal properties also. Most of these spices find considerable mention in Ayurveda, the indigenous system of medicine, as panaceas for several aliments. Cinnamomum zeylanicum (CZ), belonging to family Lauraceae and commonly known as cinnamon is one such spice known to have diverse medicinal properties since time immemorial. In the present study, apoptotic and anti-microbial activity of ethanolic extract of CZ was evaluated against human breast cancer cell line MDA-MB-231 and compared for its effect on normal kidney epithelial cell line Vero. Ethanolic extract of tree bark of CZ was used to determine the cytotoxic effect on MDA-MB-231 using Trypan blue dye exclusion method and cytometry. The tested dose of the extract was 10-100 µg/mL. Antibacterial activity was determined using disc diffusion method against Staphylococcus aureus and Escherichia coli in the range 2-10 mg/mL. Apoptotic activity was determined using DNA fragmentation assay. Ethanolic extract of CZ was found to have an IC 50 value of 25 µg/mL against MDA cell line. On the other hand, CZ extract did not have any significant effect on Vero cells even at 100 µg/mL (IC 50 > 100 µg/mL). The ethanolic extract of CZ bark showed significant antibacterial activity against S. aureus at 10 mg/mL while no appreciable activity was detected against E. coli. DNA isolated from extract treated cancer cells showed a fragmentation pattern characteristic of apoptosis. However, no DNA fragmentation was observed in DNA isolated from extract treated Vero cells. Ethanolic bark extract of CZ could be potentially beneficial in treating breast cancer and may be of interest for future studies in developing integrative cancer therapy against proliferation, metastasis, and migration of breast cancer cells.

To describe dietary sodium intakes and resources among residents in Shandong province. A total of 2184 subjects were selected by multi-stage stratified cluster random sampling method from 18-69 years old people in Shandong province in June, 2011. A total of 2140 subjects completed the study, the completion rate was 98.0%. Three-day (24-hour per day) dietary recalls and weighting methods were conducted to collect information about all the foods and condiments consumed by the subjects. Individual dietary sodium intake was calculated, the differences of dietary sodium intake among subjects with different characteristics were analyzed, and the proportions of different dietary sodium resources were also analyzed. The amount of individual dietary sodium intake was 5745.0 (95%CI:5427.6-6062.5) mg/d in Shandong; 6147.4 (95%CI: 5823.8-6471.0) mg/d for male residents, 5339.3 (95%CI:5005.8-5672.8) mg/d for female residents. There was a significant difference between males and females (F = 75.22, P < 0.01). The amount of individual dietary sodium intake was 5910.1 (95%CI:5449.3-6370.8) mg/d, 5341.6 (95%CI:5007.0-5676.1) mg/d for rural residents and urban residents respectively, and there was also a significant difference (F = 5.53, P < 0.05). The amount of condiment sodium intake was 4640.3 (95%CI:4360.2-4920.4) mg/d, which was the largest contributor to sodium intake, accounting for 80.8% (95%CI:79.9%-81.6%) of total intake. Sodium intake from cereals was 650.7 (95%CI: 590.5-711.0) mg/d, accounting for 11.3% (95%CI:10.3%-12.3%) of total intake. Sodium intake from eggs was 118.9 (95%CI:95.2-142.6) mg/d, accounting for 2.1% (95%CI:1.6%-2.6%) of total intake. The amount of manufactured food sodium intake was 582.1(95%CI: 497.8-666.4) mg/d, accounting for 10.1% (95%CI:8.9%-11.4%) of total intake. Sodium intakes remain high among residents of Shandong province, and sodium from condiments was the largest source of dietary sodium intake, sodium of manufactured food only accounting for small part.

The current performance indicator for universal salt iodisation (USI) is the percentage of households using adequately iodised salt. However, the proportion of dietary salt from household salt is decreasing with the increase in consumption of processed foods and condiments globally. This paper reports on case studies supported by the Global Alliance for Improved Nutrition (GAIN)-UNICEF USI Partnership Project to investigate processed food industry use of adequately iodised salt in contrasting national contexts. Studies were conducted in Egypt, Indonesia, the Philippines, the Russian Federation, and Ukraine. In all cases, the potential iodine intake from iodised salt in selected food products was modelled according to the formula: quantity of salt per unit of food product × minimum regulated iodine level of salt at production × average daily per capita consumption of the product. The percent of adult recommended nutrient intake for iodine potentially provided by the average daily intake of bread and frequently consumed foods and condiments was from 10% to 80% at the individual product level. The potential contribution to iodine intake from the use of iodised salt in the processed food industry is of growing significance. National USI strategies should encourage co-operative industry engagement and include regulatory monitoring of iodised salt use in the food industry in order to achieve optimal population iodine status.

Despite recent advances in food production technology, food-borne diseases (FBD) remain a challenging public health concern. In several countries, including Brazil, Clostridium perfringens is among the five main causative agents of food-borne diseases. The present study determines antimicrobial activities of essential oils of six condiments commonly used in Brazil, viz., Ocimum basilicum L. (basil), Rosmarinus officinalis L. (rosemary), Origanum majorana L. (marjoram), Mentha × piperita L. var. Piperita (peppermint), Thymus vulgaris L. (thyme) and Pimpinella anisum L. (anise) against C. perfringens strain A. Chemical compositions of the oils were determined by GC-MS (gas chromatography-mass spectrometry). The identities of the isolated compounds were established from the respective Kováts indices, and a comparison of mass spectral data was made with those reported earlier. The antibacterial activity was assessed from minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) using the microdilution method. Minimum inhibitory concentration values were 1.25mgmL(-1) for thyme, 5.0mgmL(-1) for basil and marjoram, and 10mgmL(-1) for rosemary, peppermint and anise. All oils showed bactericidal activity at their minimum inhibitory concentration, except anise oil, which was only bacteriostatic. The use of essential oils from these common spices might serve as an alternative to the use of chemical preservatives in the control and inactivation of pathogens in commercially produced food systems.

PubMed

Hagen, M; Beneke, B

2000-01-01

In this study, the application of a qualitative and a quantitative method of analysis to detect genetically modified RR-Soy (Roundup-Ready Soy) in processed foods is described. A total of 179 various products containing soy such as baby food and diet products, soy drinks and desserts, tofu and tofu products, soy based meat substitutes, soy protein, breads, flour, granules, cereals, noodles, soy bean sprouts, fats and oils as well as condiments were investigated following the pattern of the section 35 LMBG-method L 23.01.22-1. The DNA was extracted from the samples and analysed using a soybean specific lectin gene PCR as well as a PCR, specific for the genetic modification. Additional, by means of PCR in combination with fluorescence-detection (TaqMan 5'-Nuclease Assay), suspicious samples were subjected to a real-time quantification of the percentage of genetically modified RR-Soy. The methods of analysis proved to be extremely sensitive and specific in regard to the food groups checked. The fats and oils, as well as the condiments were the exceptions in which amplifiable soy DNA could not be detected. The genetic modification of RR-Soy was detected in 34 samples. Eight of these samples contained more than 1% of RR-Soy. It is necessary to determine the percentage of transgenic soy in order to assess whether genetically modified ingredients were deliberately added, or whether they were caused by technically unavoidable contamination (for example during transportation and processing).

Soy-daddawa, a fermented soybean (Glycine max (L.) Merr.) condiment, plays a significant role in the culinary practice of West Africa. It is essential to understand the microbial community of soy-daddawa for a successful starter culture application. This study investigated the microbial community structure of soy-daddawa samples collected from Nigerian markets, by PCR-denaturing gradient gel electrophoresis (DGGE) targeting the V3-V5 region of the 16S rRNA gene of bacteria and internal transcribed spacer 2 (ITS2) region of fungi. Six bacterial and 16 fungal (nine yeasts and seven molds) operational taxonomic units (OTUs)/species were obtained at 97% sequence similarity. Taxonomic assignments revealed that bacterial OTUs belonged to the phyla Firmicutes and Actinobacteria, and included species from the genera Atopostipes, Bacillus, Brevibacterium and Nosocomiicoccus. Densitometric analysis of DGGE image/bands revealed that Bacillus spp. were the dominant OTU/species in terms of population numbers. Fungal OTUs belonged to the phyla Ascomycota and Zygomycota, and included species from the genera, Alternaria, Aspergillus, Candida, Cladosporium, Dokmaia, Issatchenkia, Kodamaea, Lecythophora, Phoma, Pichia, Rhizopus, Saccharomyces and Starmerella. The majority of fungal species have not been previously reported in soy-daddawa. Potential opportunistic human pathogens such as Atopostipes suicloacalis, Candida rugosa, Candida tropicalis, and Kodamaea ohmeri were detected. Variation in soy-daddawa microbial communities amongst samples and presence of potential opportunistic pathogens emphasises the need for starter culture employment and good handling practices in soy-daddawa processing.

2014-01-01

Objective To conduct a survey on the common name/s, traditional uses and cultural importance of the edible wild fruits in different municipalities of Benguet, Cordillera administrative region. Methods Interviews using questionnaires with barangay leaders and indigenous people were conducted with 176 key informants from June 2011 to July 2013. Results A total of 36 fruit species were found in different municipalities of Benguet. These fruit species belong to 27 genera and 20 families. Among the 13 municipalities of Benguet, Kibungan has the highest number of species. There are many uses of wild fruits which ranged from food (snack/dessert/table food), forage (especially for birds, monkeys and wild animals such as cloud rat and grass eaters), offertory, processed/preserved (as jam, jellies, candies, juice and wine), condiment or ingredient (for cooking), source of dye or ink, decoration (to garnish food) and as medicine to common ailments or health problems. Based on the inventory and calculated cultural importance index, Garcinia binucao (balokok) belonging to Clusiaceae is the most abundant fruit, hence it is the commonly used fruit for various purposes such as food, forage, processing/preservation and condiment/ingredient; Vaccinium myrtoides (ayusip) for offerings and as source of dye/ink; Saurauia elegans (uyok) for decoration, and, Antidesma bunius (bugnay) for medicine. Conclusions Benguet province in the Cordillera region provides a diversity of edible wild fruits. The data gathered from the study signifies that collection, processing and utilization of edible wild fruits are still part of the daily activities of the people in Benguet. PMID:25183144

In the Asian region, indigenous fermented foods are important in daily life. In many of these foods, yeasts are predominant and functional during the fermentation. The diversity of foods in which yeasts predominate ranges from leavened bread-like products such as nan and idli, to alcoholic beverages such as rice and palm wines, and condiments such as papads and soy sauce. Although several products are obtained by natural fermentation, the use of traditional starter cultures is widespread. This minireview focuses on the diversity and functionality of yeasts in these products, and on opportunities for research and development.

Background: Recent studies have shown inconsistent effects of sodium reduction, potassium intake, and the ratio of sodium to potassium (Na/K ratio) on hypertension and other cardiovascular diseases. Major gaps exist in knowledge regarding these issues in China. Objective: We analyzed the patterns and trends of dietary sodium intake, potassium intake, and the Na/K ratio and their relations with incident hypertension in China. Design: The China Health and Nutrition Survey cohort includes 16,869 adults aged 20–60 y from 1991 to 2009. Three consecutive 24-h dietary recalls and condiment and food weights provided detailed dietary data. Multinomial logistic regression models determined trends and patterns of sodium and potassium intake and the Na/K ratio. Models for survival-time data estimated the hazard of incident hypertension. Results: Sodium intake is decreasing but remains double the Institute of Medicine recommendations. Most sodium comes from added condiments. Adults in the central provinces have the highest sodium intake and the most rapid increase in hypertension. Potassium intake has increased slightly but is below half of the recommended amount. The Na/K ratio is significantly higher than the recommended amounts. Recent measurements of high sodium intake, low potassium intake, and high Na/K ratio have strong independent dose-response associations with incident hypertension. Conclusions: Reducing sodium in processed foods, the major public health strategy in Western countries, may be less effective in China, where salt intake remains high. Replacing sodium with potassium in salt to control and prevent hypertension in China should be considered along with other public health and clinical prevention options. PMID:24257724

In China, population-based blood pressure levels and prevalence of hypertension are increasing. Meanwhile, sodium intake, a major risk factor for hypertension, is high. In 2011, to develop intervention priorities for a salt reduction and hypertension control project in Shandong Province (population 96 million), a cross-sectional survey was conducted to collect information on sodium intake and hypertension prevalence, awareness, treatment, and control. Complex, multistage sampling methods were used to select a provincial-representative adult sample. Blood pressure was measured and a survey conducted among all participants; condiments were weighed in the household, a 24-hour dietary recall was conducted, and urine was collected. Hypertension was determined by blood pressure measured on a single occasion and self-reported use of antihypertension medications. Overall, 23.4% (95% confidence interval [CI], 20.9%-26.0%) of adults in Shandong were estimated to have hypertension. Among those classified as having hypertension, approximately one-third (34.5%) reported having hypertension, approximately one-fourth (27.5%) reported taking medications, and one-seventh (14.9%) had their blood pressure controlled (<140/<90 mm Hg). Estimated total average daily dietary sodium intake was 5,745 mg (95% CI, 5,428 mg-6,063 mg). Most dietary sodium (80.8%) came from salt and high-salt condiments added during cooking: a sodium intake of 4,640 mg (95% CI, 4,360 mg-4,920 mg). The average daily urinary sodium excretion was 5,398 mg (95% CI, 5,112 mg-5,683 mg). Hypertension and excessive sodium intake in adults are major public health problems in Shandong Province, China.

In France, in most nursing homes, the composition of menus, the time and the place at which meals are served, the choice of one's place at the table are imposed on residents. Yet, the act of eating cannot be restricted to nutritional and sensory aspects alone. It also includes a psycho-affective dimension, which relates to the context in which the meal is served. We tested the impact of four contextual factors, considered individually, on food intake and meal pleasure in elderly people living in nursing homes: the way the main course was named on the menu, the size and the variety of portions of vegetables served to residents, the presence or not of condiments in the middle of the table and the presence or not of elements to modify the surroundings such as a decorative object on the table or background music. Twelve experimental meals were served to 42 nursing home residents. For each factor, we compared a control condition with two experimental conditions. Our study showed that changing a single contextual element of the meal in nursing homes could be sufficient to improve residents' satisfaction with their meals and increase the quantities of meat or vegetables consumed, as long as this factor had a direct impact on what was going to be consumed (increased variety on the plate, condiments on the table). Factors affecting the context of the meal (names of dishes, decor) proved to be ineffective. Given the budgetary constraints faced by nursing homes, this study proposes interesting and inexpensive ideas to increase satisfaction with meals and food intake in elderly people who are dependent on others for their meals.

The applicability of the epr technique for the detection of dried vegetables, mushrooms, some spices, flavour additives and some condiments preserved with ionizing radiation is discussed. The epr signals recorded after exposure to gamma rays and to beams of 10 MeV electrons from linac are stable, intense and specific enough as compared with those observed with nonirradiated samples and could be used for the detection of irradiation. However, stability of radiation induced epr signals produced in these foods depends on storage condition. No differences in shapes (spectral parameters) and intensities of the epr spectra recorded with samples exposed to the same doses of gamma rays ( 60Co) and 10 MeV electrons were observed

We examined reporting accuracy by meal component (beverage, bread, breakfast meat, combination entrée, condiment, dessert, entrée, fruit, vegetable) with validation-study data on 455 fourth-grade children (mean age = 9.92 ± 0.41 years) observed eating school meals and randomized to one of eight dietary recall conditions (two retention intervals [short, long] crossed with four prompts [forward, meal-name, open, reverse]). Accuracy category (match [observed and reported], omission [observed but unreported], intrusion [unobserved but reported]) was a polytomous nominal item response variable. We fit a multilevel cumulative logit model with item variables meal component and serving period (breakfast, lunch) and child variables retention interval, prompt and sex. Significant accuracy category predictors were meal component (p < 0.0003), retention interval (p < 0.0003), meal-component × serving-period (p < 0.0003) and meal-component × retention-interval (p = 0.001). The relationship of meal component and accuracy category was much stronger for lunch than breakfast. For lunch, beverages were matches more often, omissions much less often and intrusions more often than expected under independence; fruits and desserts were omissions more often. For the meal-component × retention-interval interaction, for the short retention interval, beverages were intrusions much more often but combination entrées and condiments were intrusions less often; for the long retention interval, beverages were matches more often and omissions less often but fruits were matches less often. Accuracy for each meal component appeared better with the short than long retention interval. For lunch and for the short retention interval, children’s reporting was most accurate for entrée and combination entrée meal components, whereas it was least accurate for vegetable and fruit meal components. Results have implications for conclusions of studies and interventions assessed with dietary recalls obtained from children. PMID:28174038

In summer of 2008, the United States witnessed one of the largest multi-state salmonellosis outbreak linked to the consumption of Jalapeño and Serrano peppers tainted with Salmonella enterica serovar Saintpaul. The first objective of this study was to assess the application of high hydrostatic pressure (HHP) to decontaminate Jalapeño and Serrano peppers from this pathogen. Jalapeño and Serrano peppers were inoculated with a five-strain cocktail of Salmonella to a final level of ca. ~6 log CFU/g and subsequently pressure-treated in the un-wetted, wetted (briefly dipped in water) or soaked (immersed in water for 30 min) state at 300-500 MPa for 2 min at 20°C. The extent of pressure inactivation increased as a function of the pressure level and in the order of soaked>wetted>un-wetted state achieving population reductions ranging from 1.1 to 6.6 log CFU/g. Overall, pressure treatment at 400-450 MPa (soaked) or 450-500 MPa (wetted) for 2 min at 20°C rendered Salmonella undetectable. Since salsa and guacamole are two examples of widely consumed Mexican dishes that incorporate raw Jalapeño and Serrano peppers, we subsequently investigated the pressure-inactivation of Salmonella in salsa and guacamole, originating from contaminated peppers used as ingredients. The storage time (0, 12 or 24 h) of the condiments prior to HHP as well as the pH (3.8-5.3) and the type of acidulants (vinegar and lemon juice) used all influenced the extent of Salmonella inactivation by HHP. This study demonstrates the dual efficacy of HHP to decontaminate fresh chile peppers destined for direct consumption and minimally process condiments possibly contaminated with raw peppers to enhance their microbiological safety.

2016-12-01

There is an established framework of international standards for food irradiation covering human health, plant protection, labelling, dose delivery, quality assurance and facility management. Approximately 60 countries permit irradiation of one or more food or food classes. National regulations are briefly reviewed. Decontamination of spices, herbs and condiments remains the single largest application of irradiation. However, in recent years the market for irradiated fresh and processed meat has become firmly established in several countries including China and the USA. At least 10 countries have recently established bi-lateral agreements for trade in irradiated fresh fruits and vegetables using phytosanitary irradiation. Irradiated fresh produce volumes now exceed 20,000 t per year. Rationalization and greater consistency in labelling regulations would be advantageous to the future growth of applications of food irradiation.

Blueberry pomace (BP) and cranberry pomace (CP) are good sources of dietary fiber and phenolics. This study aimed to develop berry fruit pomace (FP)-fortified specialty mustard with elevated bioactive compounds and ascertain consumer acceptance of a new product. Wet BP and CP were ground and incorporated into Dijon-style mustard at concentrations of 15%, 20%, and 25% (w/w). Total dietary fiber (TDF), total phenolic content (TPC), and radical scavenging activity (RSA) were evaluated for samples obtained from both chemical extraction (CE) and simulated gastrointestinal digestion (SGD). Physicochemical properties and consumer acceptance were also examined. Increasing concentrations of BP or CP significantly increased TDF of mustards from both CE (AOAC methods) and SGD, with the highest values from 25% fortifications. TDF from AOAC ranged from 26.86% to 40.16% for BP and from 26.86% to 38.42% for CP, while TDF from SGD ranged from 31.02% to 42.68% for BP and 31.02% to 63.65% for CP. From CE, no significant variation of TPC was found, but RSA significantly increased with increasing concentration of BP and CP. TPC from SGD was higher than that from CE, where TPC decreased with increasing concentration of BP or CP. RSA from SGD was lower than that from CE. Sensory scores of pomace-fortified samples were significantly lower than the control; however, informed panelists scored BP-fortified mustard significantly higher on appearance and color liking than uninformed panelists. This study demonstrated that with proper marketing, the utilization of FP in condiments is a viable option for potential health benefits. This research is applicable to multiple areas of the food industry. Juice manufacturers or other companies that process raw agricultural produce can use this research as another way to repurpose biowaste, and companies making specialty condiments can use this research to inform future product development. General considerations discussed regarding the use of berry fruit pomace can be applied by any company interested in pomace reuse. © 2018 Institute of Food Technologists®.

In this work, mineral contents of 4 plants used in Iran were determined by Inductively Coupled Plasma-Atomic Emission Spectrometry. The concentrations were calculated on a dry weight basis. All materials contained high amounts of Na, Al, Ca, Fe, K, Mg, P, Zn, and I. On a moisture-free basis, the highest levels of Ca, P, and Mg were found in spinach to be 3200 mg/100 g, 2150 mg/100 g, and 460 mg/100 g, respectively. Bi, Cd, Li, Pb, and Se contents of condiments were found to be very low. The results were compared with those from the Spanish, Turkish, and Indian. This work attempts to contribute to knowledge of the nutritional properties of these plants. These results may be useful for the evaluation of dietary information and concluded that the green vegetables are the good sources of minerals.

Ginger is a commonly used spice and herbal medicine worldwide. Besides its extensive use as a condiment, ginger has been used in traditional Chinese medicine for the management of various medical conditions. In recent years, ginger has received wide attention due to its observed antiemetic and anticancer activities. This paper reviews the potential role of ginger and its active constituents in cancer chemoprevention. The phytochemistry, bioactivity, and molecular targets of ginger constituents, especially 6-shogaol, are discussed. The content of 6-shogaol is very low in fresh ginger, but significantly higher after steaming. With reported anti-cancer activities, 6-shogaol can be served as a lead compound for new drug discovery. The lead compound derivative synthesis, bioactivity evaluation, and computational docking provide a promising opportunity to identify novel anticancer compounds originating from ginger.

Horseradish (Armoracia rusticana) is a perennial crop belonging to the Brassicaceae family. Horseradish root is used as a condiment due to its extremely pungent flavour, deriving from the high content of glucosinolates and their breakdown products such as isothiocyanates and other sulfur compounds. Horseradish also has a long history in ethnomedicine. In this study the anti-inflammatory potential of three accessions of Armoracia rusticana on lipopolysaccharide from E. coli treated J774A.1 murine macrophages was evaluated. Our results demonstrate that Armoracia rusticana reduced nitric oxide, tumor necrosis factor-α and interleukin-6 release and nitric oxide synthase and cyclooxygenase-2 expression in macrophages, acting on nuclear transcription factor NF-κB p65 activation. Moreover Armoracia rusticana reduced reactive oxygen species release and increased heme-oxygenase-1 expression, thus contributing to the cytoprotective cellular effect during inflammation.

Umami, the fifth basic taste, is the inimitable taste of Asian foods. Several traditional and locally prepared foods and condiments of Asia are rich in umami. In this part of world, umami is found in fermented animal-based products such as fermented and dried seafood, and plant-based products from beans and grains, dry and fresh mushrooms, and tea. In Southeast Asia, the most preferred seasonings containing umami are fish and seafood sauces, and also soybean sauces. In the East Asian region, soybean sauces are the main source of umami substance in the routine cooking. In Japan, the material used to obtain umami in dashi, the stock added to almost every Japanese soups and boiled dishes, is konbu or dried bonito. This review introduces foods and seasonings containing naturally high amount of umami substances of both animal and plant sources from different countries in Asia.

Levels of iodine of foods found in Hong Kong were analysed in 271 samples from 11 groups, including (i) cereals and grain products, (ii) legumes and vegetables, (iii) meat and poultry, (iv) egg and egg products, (v) milk and milk products, (vi) fish, (vii) crustaceans and mollusks, (viii) non-alcoholic beverages, (ix) condiments and sauces, (x) sashimi and (xi) seaweeds. All food samples were analysed individually as purchased. The iodine in all samples ranged from undetectable to 2.9 g kg(-1). Seaweeds, iodised salt, seafood, milk and milk products as well as egg and egg products were rich sources of iodine. To estimate the influence of cooking on iodine levels in foods, a total of 15 individual samples were analysed as raw and respective cooked food. The influence of cooking on the iodine level was minimal, except for boiling, as iodine dissolved into the soup.

To investigate the contamination of aflatoxins in food in Shaanxi Province, and provide the basic data of dietary intakes of aflatoxins for food safety assessment. In year 2012- 2015, 1007 food samples of eight kinds of food including grains, beans, vegetable oil, nuts and seeds, condiment, liquor, tea and infants' food were collected randomly from ten cities, and determined with UPLC. 1007 samples were detected aflatoxins and the total detection rate was 10. 7%. The detection range was 0. 070- 323 μg / kg, with the mean value of 2. 34 μg / kg. Among all food samples, only peanut products were more seriously polluted than other kinds of foods. The overall level of aflatoxins contamination in market food is low, but peanut products might be the contaminated foods with aflatoxins in Shaanxi Province, and should be given more attention.

Wasabi or Japanese horseradish (Eutrema japonicum) is both a traditional condiment and a medicinally important plant with diverse uses. Its medicinally active constituents appear to include five isothiocyanates, but their spatial variations in naturally occurring congeners are unknown. Thus, in this study we measured concentrations of these five active constituents in 20 populations of 14 species of Eutrema and one related species, Yinshania sinuata. Three to five of these constituents were detected in each of the examined species, at concentrations that varied greatly between sampled species and populations of the same species. However, two species, Eutrema tenue and Eutrema deltoideum, had higher total concentrations of the five isothiocyanates and substantially higher concentrations of one or two, than the widely cultivated E. japonicum. Thus, both of these species could be important wild resources for artificial cultivation, in addition to the currently widely cultivated E. japonicum. Copyright © 2016 Elsevier B.V.

Rosmarinus eriocalyx is an aromatic evergreen bush endemic to Algeria where it is used as a condiment to flavour soups and meat and as a traditional remedy. In the present work we have analyzed for the first time the phenolic composition of polar extracts obtained from stems, leaves and flowers of R. eriocalyx by HPLC, and determined the antioxidant and antimicrobial effects by DPPH, ABTS, FRAP, ORAC and agar disc diffusion methods, respectively. Results showed that ethanolic extracts of leaves and flowers are a rich source of phenolic compounds, mainly rosmarinic acid, carnosic acid and carnosol that are the main responsible for the noteworthy antioxidant activity observed in the assays. This study showed that R. eriocalyx might be a spice to be included in the European food additive list and used as a preservative agent besides R. officinalis. Copyright © 2016 Elsevier Ltd.

Horseradish (Armoracia rusticana) is a perennial crop and its ground root tissue is used in condiments because of the pungency of the glucosinolate (GS)-hydrolysis products allyl isothiocyanate (AITC) and phenethyl isothiocyanate (PEITC) derived from sinigrin and gluconasturtiin, respectively. Horseradish roots are sold in three grades: U.S. Fancy, U.S. No. 1, and U.S. No. 2 according to the USDA standards. These grading standards are primarily based on root diameter and length. There is little information on whether root grades vary in their phytochemical content or potential health promoting properties. This study measured GS, GS-hydrolysis products, potential anticancer activity (as quinone reductase inducing activity), total phenolic content, and antioxidant activities from different grades of horseradish accessions. U.S. Fancy showed significantly higher sinigrin and AITC concentrations than U.S. No. 1 ,whereas U.S. No. 1 showed significantly higher concentrations of 1-cyano 2,3-epithiopropane, the epithionitrile hydrolysis product of sinigrin, and significantly higher total phenolic concentrations than U.S. Fancy.

Kaempferia galanga L. (Zingiberaceae) is an aromatic herb and a popular spice used as a condiment in Asian cuisine. The ethanol extract of the dried plant and its successive four subfractions were investigated on zebrafish model by quantitative endogenous alkaline phosphatase assay. Both n-hexane and ethyl acetate fractions had antiangiogenic activity, and two major active components (trans-ethyl p-methoxycinnamate and kaempferol) showed potent antiangiogenic effects on wild-type zebrafish. Because of its much stronger effect and no antiangiogenic activity reported, trans-ethyl p-methoxycinnamate was further investigated for its action mechanism. It dose dependently inhibited vessel formation on both wild- and Tg(fli1a:EGFP)y1-type zebrafish embryos. The semiquantitative reverse transcription polymerase chain reaction assay suggested that trans-ethyl p-methoxycinnamate affects multiple molecular targets related to angiogenesis. In vitro, it specifically inhibited the migration and tube formation of human umbilical vein endothelial cells. In vivo, it could block bFGF-induced vessel formation on Matrigel plug assay.

A strict, lifelong gluten-free (GF) diet is currently the only treatment for coeliac disease (CD). Vinegar and soy sauce are fermented condiments that often include wheat and/or barley. During fermentation cereal proteins are partially degraded by enzymes to yield peptide fragments and amino acids. Whether these fermented products contain intact or degraded gluten proteins and if they are safe for people with CD remains in question. LC-MS offers the benefit of being able to detect hydrolysed gluten that might be present in commercial vinegar and soy sauce products. LC-MS revealed the presence of gluten in malt vinegar, wherein the identified peptides derived from B-, D- and γ-hordein from barley, as well as γ-gliadin, and HMW- and LMW-glutenins from wheat that are known to contain immunopathogenic epitopes. No gluten was detected in the soy sauces examined despite wheat being a labelled ingredient indicating extensive hydrolysis of gluten during soy sauce production. Copyright © 2018 Elsevier Ltd.

Fish sauce is a traditional condiment in Southeast Asia, normally containing high concentration of salt. The solubility of salt is lower in ethanol than in water. In the present study, fish sauce was desalted by ethanol treatment (including the processes of ethanol addition, mixing, standing and rotary evaporation). The salt concentration of fish sauce decreased significantly from 29.72 to 19.72 g/100 mL when the treated ethanol concentration was 21% (v/v). The addition of more than 12% (v/v) of ethanol significantly reduced dry weight, total soluble nitrogen content and amino acids nitrogen content. Besides, the quality of fish sauce remained first grade if no more than 21% (v/v) of ethanol was used. Furthermore, sensory analyses showed that ethanol treatment significantly reduced the taste of salty and the odor of ammonia. This study demonstrates that ethanol treatment is a potential way to decrease salt content in fish sauce, which meanwhile limits the losses of nutritional and sensorial values within an acceptable range.

Food fortification is a widely used approach to increase micronutrient intake in the diet. High coverage is essential for achieving impact. Data on coverage is limited in many countries, and tools to assess coverage of fortification programs have not been standardized. In 2013, the Global Alliance for Improved Nutrition developed the Fortification Assessment Coverage Toolkit (FACT) to carry out coverage assessments in both population-based (i.e., staple foods and/or condiments) and targeted (e.g., infant and young child) fortification programs. The toolkit was designed to generate evidence on program coverage and the use of fortified foods to provide timely and programmatically relevant information for decision making. This supplement presents results from FACT surveys that assessed the coverage of population-based and targeted food fortification programs across 14 countries. It then discusses the policy and program implications of the findings for the potential for impact and program improvement.

Budu is a famous Malaysian fish sauce, usually used as seasoning and condiment in cooking. Budu is produced by mixing fish and salt at certain ratio followed by fermentation for six months in closed tanks. In this study, four commercial brands of Budu were analyzed for their chemical properties (pH, salt content and volatile compounds). The pH of Budu samples ranged from 4.50-4.92, while the salt (NaCl) content ranged between 11.80% and 22.50% (w/v). For tentative identification of volatile flavor compounds in Budu, two GC columns have been used, DB-WAX and HP-5MS. A total of 44 volatile compounds have been detected and 16 were common for both columns. 3-Methyl-1-butanol, 2-methylbutanal, 3-methylbutanal, dimethyl disulfide, 3-(methylthio)-propanal, 3-methylbutanoic acid and benzaldehye have been identified as the aroma-active compounds in Budu due to their lower threshold values.

The aim of this investigation was to produce an olive oil (OO) naturally enriched with antioxidants, recovering carotenoids, in particular lycopene, using an industrial by-product of tomato seeds and skin. For this purpose, a technological process in a low-scale industrial plant to co-mill olives and tomato by-product in de-frosted or freeze-dried forms was applied and studied with respect to control samples. Preliminary results obtained from two different experiments were carried out by 40 kg of cultivar Correggiolo olives and 60 kg of olive blends from different cultivars. In both the experiments, the co-milling showed significant enrichment in carotenoids, especially in lycopene (mean values of 5.4 and 7.2 mg/kg oil from defrosted and freeze-dried by-products, respectively). The experimental results demonstrated the possibility to obtain a new functional food naturally enriched in antioxidant compounds, which might be marketed as "OO dressing enriched in lycopene" or "condiment produced using olives and tomato by-product".

Turmeric is a rhizomatous herbaceous perennial but cultivated as annual, belonging to the family Zingiberaceae. It is a native of India and South East Asia. The tuberous rhizomes or underground stems of turmeric are used from antiquity as condiments, a dye and as an aromatic stimulant in several medicines. Turmeric is an important crop in India and it is used as a spice, food preservative, coloring agent, cosmetic as well as for its medicinal properties. Propagation is done vegetatively with rhizome bits as seed materials. It is plagued by rhizome rot diseases most of which are mainly spread through infected seed rhizomes. Micropropagation will help in production of disease-free seed. Sexual reproduction is rare in turmeric, making recombinant breeding very difficult. In vitro technology can thus become the preferred choice and it can be utilized for multiplication, conservation of genetic resources, generating variability, gene transfer, molecular tagging, and their utility in crop improvement.

Chili pepper (Capsicum annuum) is the most important and emblematic condiment in Mexican food. Serrano pepper is a variety of C. annuum that is traditionally cultivated in Mexico and commercialized in local markets. The aim of this study was to describe the 1 H NMR metabolomic profiling of the aqueous phase of serrano peppers harvested from two distinct regions, in the states of Veracruz and Oaxaca, Mexico. According to the current results, aspartate citrate, lactate, leucine and sucrose were found at higher amount in the serrano peppers from Veracruz. On the other hand, acetate, formate, fumarate, malonate, phosphocholine, pyruvate and succinate showed the highest abundance in this product from Oaxaca. These are the main metabolites that distinguish one group from the other. The spectrometric method reported presently is characterized by great simplicity, robustness and reproducibility. Thus, this technique can be used for establishing reliable metabolomic fingerprints of serrano peppers grown under different environmental conditions. Copyright © 2017 Elsevier Ltd.

Saffron, the dried stigmas of Crocus sativus L., is used as a condiment spice. The major bioactive compounds are crocins, picrocrocin and safranal, which are responsible for the sensory profile of saffron (color, flavor and aroma, respectively), and also health-promoting properties. In this paper, the effect on the bioactive compounds of different cooking times in boiling water at 100 °C in samples of Saffron from La Mancha (safranal, picrocrocin, trans-crocin 4, cis-crocin 4 and trans-crocin 3) was investigated. Performance characteristics of High Performance Liquid Chromatography with Variable Wavelength Detector method, parameters of linearity, limits of detection and quantification are reported. High Performance Liquid Chromatography-Photo Diode Array-Mass Spectrometry was used as a confirmatory technique in crocins identification. When the samples are subjected to different cooking times, they present different behaviors, depending on the bioactive compound. In this way, no changes were observed in the concentration of picrocrocin, while heat culinary treatment adversely affects the concentrations of crocins and safranal.

Ginger is a rhizomatous plant that belongs to the family Zingiberaceae. It is a herbaceous perennial but cultivated as annual, with crop duration of 7-10 months. Ginger is native to India and Tropical South Asia. The tuberous rhizomes or underground stems of ginger are used as condiment, an aromatic stimulant, and food preservative as well as in traditional medicine. Ginger is propagated vegetatively with rhizome bits as seed material. Cultivation of ginger is plagued by rhizome rot diseases, most of which are mainly spread through infected seed rhizomes. Micropropagation will help in production of disease-free planting material. Sexual reproduction is absent in ginger, making recombinant breeding very impossible. In vitro technology can thus become the preferred choice as it can be utilized for multiplication, conservation of genetic resources, generating variability, gene transfer, molecular tagging, and their utility in crop improvement of these crops.

Development by extrusion of soyabari snack sticks: a nutritionally improved soya-maize product based on the Nigerian snack (kokoro).

1996-01-01

A nutritionally improved local snack compared to existing kokoro has been developed by extrusion cooking of different formulations of maize, soybean and condiments such as pepper, onion, salt, palm oil, plantain and banana. The improved snack was named as the 'soyabari snack stick'. The chemical composition of representative extruded products indicates a high level of crude protein, fat, energy, available lysine and improved in vitro digestibility compared to the usual maize-based products. The level of stachyose and raffinose were greatly reduced in the extruded products compared to raw soya. Formulations using various additives yielded products suitable for different consumers' preferences such as hot, sweet, bland, gritty or crispy and acceptable to taste assessors. Soyabari snack sticks were equally acceptable as Bombay mix, a product on the market in London. Sensory analysis showed no significant differences in the two products but the crude fibre content of Bombay mix was higher while the protein was slightly lower than for soyabari sticks. Local ingredients can produce acceptable extrudates.

Cooking is widely recognized as an important source of indoor and outdoor particle and volatile organic compound emissions with potential deleterious effects on human health. Nevertheless, cooking emissions remain poorly characterized. Here the effect of herbs and pepper on cooking emissions was investigated for the first time to the best of our knowledge using state of the art mass spectrometric analysis of particle and gas-phase composition. Further, the secondary organic aerosol production potential of the gas-phase emissions was determined by smog chamber aging experiments. The emissions of frying meat with herbs and pepper include large amounts of mono-, sesqui- and diterpenes as well as various terpenoids and p-cymene. The average total terpene emission rate from the use of herbs and pepper during cooking is estimated to be 46 ± 5 gg-1Herbs min-1. These compounds are highly reactive in the atmosphere and lead to significant amounts of secondary organic aerosol upon aging. In summary we demonstrate that cooking with condiments can constitute an important yet overlooked source of terpenes in indoor air. PMID:27830718

Within the family of Brassicaceae, an important source of glucosinolates (GLSs) is represented by horseradish ( Armoracia rusticana P. Gaertner, B. Meyer & Scherbius), cultivated for its roots, which are grated fresh or processed into a sauce and used as a condiment. The characteristic pungent flavor of the root depends on the abundance of the bioactive GLS molecules. In crude plant extracts (sprouts and roots) of an accession of horseradish largely diffused in the Basilicata region (southern Italy), which develops many sprouts and produces white, fiery, and sharp-flavored marketable roots, we characterized the GLS profile by LC-ESI-LTQ-FTICR-MS and IRMPD. In sprouts and roots we identified 16 and 11 GLSs, respectively. We confirmed the presence of sinigrin, 4-hydroxyglucobrassicin, glucobrassicin, gluconasturtin, and 4-methoxyglucobrassicin and identified glucoiberin, gluconapin, glucocochlearin, glucoconringianin, glucosativin, glucoibarin, 5-hydroxyglucobrassicin, glucocapparilinearisin or glucobrassicanapin, glucotropaeolin, and glucoarabishirsutain, not previously characterized in horseradish. Of particular note was the presence of the putative 2-methylsulfonyl-oxo-ethyl-GLS.

The manufacture of dry fermented sausages is an important part of the meat industry in Southern European countries. These products are usually produced in small shops from a mixture of pork, fat, salt, and condiments and are stuffed into natural casings. Meat sausages are slowly cured through spontaneous fermentation by autochthonous microbiota present in the raw materials or introduced during manufacturing. The aim of this work was to evaluate the technological and safety features of coagulase-negative staphylococci (CNS) isolated from Portuguese dry fermented meat sausages in order to select autochthonous starters. Isolates (n = 104) obtained from 2 small manufacturers were identified as Staphylococcus xylosus, Staphylococcus equorum, Staphylococcus saprophyticus, and Staphylococcus carnosus. Genomically diverse isolates (n = 82) were selected for further analysis to determine the ability to produce enzymes (for example, nitrate-reductases, proteases, lipases) and antibiotic susceptibility. Autochthonous CNS producing a wide range of enzymes and showing low antibioresistance were selected as potential starters for future use in the production of dry fermented meat sausages. © 2016 Institute of Food Technologists®

A rapid and sensitive UHPLC-MS/MS method followed by modified QuEChERS was developed for the simultaneous determination of seven biogenic amines in soy sauce. Samples were firstly diluted by water and pH values of which were adjusted using ammonia water. Modified QuEChERS method was adopted for the purification and 1, 7-heptyldiamine was used as the internal standard. Analysis of seven biogenic amines was within 4min. Under the optimized conditions, linear relations were favorable over the selected concentration ranges of 3.0-600μg/L with correlationcoefficients greater than 0.999. The average accuracy was between 84% and 115%. Intra- and inter- assay precisions for six replicates ranged from 2.2% to 8.8% or below 12%, respectively. The method limits of detection and the method limits of quantitation were 4-8μg/kg and 15-30μg/kg, respectively. The method was successfully applied to determine the concentrations of seven biogenic amines in soy sauces. Copyright © 2017 Elsevier Ltd. All rights reserved.

The antifungal activities of novel 2,3-unsaturated and 2,3-dideoxy 1-O-glucosides of carvacrol, thymol, and perillyl alcohol were tested against Aspergillus flavus, Aspergillus ochraceus, Fusarium oxysporum, Saccharomyces cerevisiae and Candida albicans. In the agar well diffusion tests, zones of inhibition for the derivatives of carvacrol, thymol and perillyl alcohol were higher (15-30mm) in the case of filamentous fungi than those for the parent compounds. Their MIC and MFC values indicated that the 2,3-unsaturated and 2,3-dideoxy 1-O-glucosides of carvacrol and thymol exhibited more fungicidal activity than the other compounds. Further, the 2,3-dideoxyglucosides of carvacrol and thymol, exhibited antitoxigenic effects against A. ochraceus and A. flavus and inhibited the production of ochratoxin and aflatoxin-B2. Propidium iodide influx assay demonstrated the lysis of C. albicans cells by carvacrol and its 2,3-unsaturated 1-O-glucoside and the loss of the membrane integrity. These new 2,3-dideoxyglucosides can be useful as antifungal agents and condiments in foods. Copyright © 2016 Elsevier Ltd. All rights reserved.

The antioxidant activity, total peroxide values, and total phenol contents of several medicinal and aromatic plant essential oil and extracts from Turkey were examined. Total phenolic contents were determined using a spectrophotometric technique and calculated as gallic acid equivalents. Total antioxidant activity of essential oil and extracts varied from 0.6853 to 1.3113 and 0.3189 to 0.6119 micromol of Trolox equivalents/g, respectively. The total phenolic content of essential oil ranged from 0.0871 to 0.5919 mg of gallic acid/g dry weight. However, the total phenolic contents of extracts were found to be higher compared with those of essential oils. The amount of total peroxide values of oils varied from 7.31 (pickling herb) to 58.23 (bitter fennel flower) mumol of H(2)O(2)/g. As a result, it is shown that medicinal plant derivatives such as extract and essential oils can be useful as a potential source of total phenol, peroxide, and antioxidant capacity for protection of processed foods.

Rhus coriaria, also known as Sumac, has been traditionally used in many countries as spice, condiment, dying agent, and medicinal herb. The chemical composition of essential oils (EOs) and the volatile emissions from different organs of this species collected in Sicily (Italy) were analyzed by gas chromatography-flame ionization detection and gas chromatography/mass spectrometry. Monoterpene and sesquiterpene hydrocarbons were the most abundant class in the volatile emissions with β-caryophyllene and α-pinene were the main constituents in the majority of the examined samples. The EO composition was characterized by high amount of monoterpene and sesquiterpene hydrocarbons together with diterpenes. The main compounds in the EO obtained from the leaves and both stages of fruit maturation were cembrene and β-caryophyllene, while α-pinene and tridecanoic acid were the key compounds in the flower EO. All the data were submitted to multivariate statistical analysis showing many differences among the different plant parts and their ontogenetic stages. © 2017 Wiley-VHCA AG, Zurich, Switzerland.

Overview on mechanisms of acetic acid resistance in acetic acid bacteria.

Wang, Bin; Shao, Yanchun; Chen, Fusheng

Acetic acid bacteria (AAB) are a group of gram-negative or gram-variable bacteria which possess an obligate aerobic property with oxygen as the terminal electron acceptor, meanwhile transform ethanol and sugar to corresponding aldehydes, ketones and organic acids. Since the first genus Acetobacter of AAB was established in 1898, 16 AAB genera have been recorded so far. As the main producer of a world-wide condiment, vinegar, AAB have evolved an elegant adaptive system that enables them to survive and produce a high concentration of acetic acid. Some researches and reviews focused on mechanisms of acid resistance in enteric bacteria and made the mechanisms thoroughly understood, while a few investigations did in AAB. As the related technologies with proteome, transcriptome and genome were rapidly developed and applied to AAB research, some plausible mechanisms conferring acetic acid resistance in some AAB strains have been published. In this review, the related mechanisms of AAB against acetic acid with acetic acid assimilation, transportation systems, cell morphology and membrane compositions, adaptation response, and fermentation conditions will be described. Finally, a framework for future research for anti-acid AAB will be provided.

Lead poisoning from atypical sources, which excludes the well-established lead-based paint ingestions and exposure in occupational settings, are increasingly reported in medical literature. Our objective is to increase awareness on atypical sources of lead exposure and to formulate recommendations for their detection based on actual reported cases. We systematically retrieved and reviewed reports on pediatric lead poisoning in the U.S. from atypical sources by searching Medline, Embase, CINAHL, Academic Search Premier, AltHealth, websites of state lead poisoning prevention programs, and the U.S. Consumer Product Safety Commission database for reports published from January 1966 to December 2006. We retrieved 28 published reports that met our inclusion criteria. Of these reports, 20 are case reports and 8 case series, documenting a total of 82 incidents of lead poisoning in children from atypical sources. There are varied sources of atypical lead exposure among U.S. children. The sources were grouped in the following categories based on their utility: fashion accessories, folk remedies, imported condiments & candies, pellets & bullets, and lastly, recreational & domestic items. Based on these findings, we have formulated a questionnaire that may assist in the identification of atypical lead sources in the home.

Micronutrient Fortification of Food in Southeast Asia: Recommendations from an Expert Workshop

Micronutrient deficiencies remain a significant public health issue in Southeast Asia, particularly in vulnerable populations, such as women of reproductive age and young children. An important nutrition-specific intervention to address micronutrient malnutrition is fortification of staple foods and condiments. In October 2013, the International Life Sciences Institute (ILSI) Southeast Asia Region held a workshop on micronutrient fortification of food in Bangkok, Thailand. The objective was to engage multiple stakeholders in a discussion on food fortification and its importance as a public health intervention in Southeast Asia, and to identify and address key challenges/gaps in and potential opportunities for fortification of foods in ASEAN countries. Key challenges that were identified include: “scaling up” and mobilizing sustainable support for fortification programs in the form of multi-stakeholder partnerships, effecting policy change to support mandatory fortification, long-term monitoring of the programs’ compliance and efficacy in light of limited resources, and increasing awareness and uptake of fortified products through social marketing campaigns. Future actions recommended include the development of terms of engagement and governance for multi-stakeholder partnerships, moving towards a sustainable business model and more extensive monitoring, both for effectiveness and efficacy and for enforcement of fortification legislation.

Bourges, H; Morales de León, J C; Sierra, H

1985-09-01

The per capita consumption of marine products is very low in Mexico, averaging less than 4 g/day. This fact has been partially attributed to the costly techniques used in their preservation, which result in high market prices unaffordable for large segments of the population. Previous research lead to the development of pressed and salted patties based on lean fish species, the low cost and easy preservation of which would contribute to a higher fish consumption among the low socio-economic strata of the Mexican population. The present work was directed to adapt the procedure to sardine, which is more abundant and less expensive than lean fish species. Since defatting the sardine lead to poor sensorial characteristics of the patties, measures were taken to protect the fat from oxidation, through the use of BHT and citric acid. The best results were obtained with descaled sardine, and with the addition of 8% NaCl, 10% corn flour and a condiment mixture. The resulting product had 32% of high-quality protein and a shelf life of at least six months under environmental conditions. Its cost per gram of protein was one-third lower than the price of fresh or canned sardine. Sensorial tests revealed an acceptability of 82%.

To identify Bacillus spp. responsible of the fermentation of Hibiscus sabdariffa for production of Bikalga, an alkaline fermented food used as a condiment in Burkina Faso. Seventy bacteria were isolated from Bikalga produced in different regions of Burkina Faso and identified by phenotyping and genotyping using PCR amplification of the 16S-23S rDNA intergenic transcribed spacer (ITS-PCR), repetitive sequence-based PCR (rep-PCR) and DNA sequencing. The isolates were characterized as motile, rod-shaped, endospore forming, catalase positive, Gram-positive bacteria. ITS-PCR allowed typing mainly at species level. Rep-PCR was more discriminative and allowed a typing at ssp. level. The DNA sequencing combined with the Blast search program and fermentation profiles using API 50CHB system allowed an identification of the bacteria as Bacillus subtilis, B. licheniformis, B. cereus, B. pumilus, B. badius, Brevibacillus bortelensis, B. sphaericus and B. fusiformis. B. subtilis were the predominant bacterium (42) followed by B. licheniformis (16). Various species and ssp. of Bacillus are involved in fermentation of H. sabdariffa for production of Bikalga. Selection of starter cultures of Bacillus for controlled production of Bikalga, selection of probiotic bacteria.

Two charred bread-like objects were found in late Neolithic Layer 13 of the pile-dwelling, and are investigated using a novel set of analyses for cereal-based foodstuffs. Tissue remains of barley and wheat were identified, as well as a schizocarp of celery (cf. Apium graveolens), providing the first evidence for the use of bread condiments in the Neolithic. Cereal particle sizes were recorded and used to draw conclusions regarding milling and sieving of the raw material. Gas bubbles in the charred objects were measured in order to evaluate possible leavening of the dough. The outcomes of this research significantly advance the understanding of the production traits of cereal-based food during the Neolithic. The analytical techniques proposed by this study open up new possibilities for systematic and consistent investigations of cereal-based archaeological foodstuffs.

National food fortification: a dialogue with reference to Asia: balanced advocacy.

2008-01-01

The vulnerability of large segments of Asia's population to micronutrient deficiency is more a consequence of cultural evolution and demography than of economic inequities. We evolved in a hunter-gatherer lifestyle with vigorous energy expenditure, wide dietary variety and a nutrient-dense diet (meat, viscera), and wound up 10,000 years ago as agriculturalists cultivating cereal and tuber crops for 70% of our dietary calories. Obtaining rice, maize and wheat is less energy intensive than needed for hunters' fare, while grains are distinctly less rich in available vitamins and minerals. Recurrent infectious episodes, transmitted in crowded societies, further deplete micronutrient nutriture. A fast-track option to address historically unprecedented life conditions includes chemical- or bio-fortification of ubiquitous condiments or widely consumed staples. With little or no change in habitual eating individuals will consume recommended micronutrient intakes and uptakes. Generous intakes of nutrients such as vitamin A and zinc counteract the adverse environmental effects on quality of life and survival in poverty situations. One size may not fit all, and over-consumption of certain micronutrients in heterogeneous societies is to be avoided. For the rice bowl to support the descendants of the caveman in the third millennium requires both imagination and technological ingenuity.

The aims of this study were to investigate the chemical composition and the antioxidant activity and antibacterial activity of the essential oil of Xylopia sericea fruits (OXS). The fruits of this species are popularly used for medicinal purposes, and as a condiment in food preparation. The chemical composition of OXS was analysed by GC/MS. 1,1-Diphenyl-2-picrylhydrazyl (DPPH) scavenging, β-carotene/linoleic acid bleaching and phosphomolybdenum and thiobarbituric acid-reactive substance (TBARS) assays were used to evaluate the antioxidant activity. Antibacterial activity was assessed by minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against bacterial strains of interest to human health and food spoilage. Eighty-four compounds were identified. The sesquiterpenes spathulenol (16.42%), guaiol (13.93%) and germacrene D (8.11%) were the most abundant constituents. OXS presented a significant antioxidant activity and also a high bacteriostatic effect against Staphylococcus aureus, Enterobacter cloacae, Bacillus cereus and Klebsiella pneumoniae. Those results evidenced the potential of OXS to treat human bacterial infections and as an antimicrobial ingredient for food preservation. © 2017 Royal Pharmaceutical Society.

Food and beverage packaging has been identified as a contributing factor to malnutrition among elderly patients in hospitals. The focus of this research was to describe the types of food and beverage packaging used in NSW hospitals, determine the 'problematic' packaging from the users' perspective, investigate the effect of hand strength on the ability to open the packaging and to survey users' (patients and staff) views on the 'accessibility' of the packaging. The study was conducted in the Illawarra region of NSW, Australia. Participants (140 mostly elderly inpatients and 64 staff members) were recruited from four local public hospitals. Data were collected using interviews, questionnaires, observations and grip strength testing. Several food and beverage packages were found difficult to open by at least 40% of patients. These included milk and juices (52%), cereal (49%), condiments (46%), tetra packs (40%) and water bottles (40%). The difficulties were attributed to 'fiddly' packaging, hand strength and vision; however, only tetra packs demonstrated a relationship between time taken to open and hand strength, suggesting other aspects of hand function may be more important than strength when opening food and beverage packages.

Ginger has been widely used as healthy food condiment as well as traditional Chinese medicine since antiquity. Multiple potentials of ginger for treatment of various ailments have been revealed. However, the biological half-life of 6-gingerol (a principal pungent ingredient of ginger) is only 7.23 minutes while taken orally. Delivery of ginger compositions by routes other than oral have scarcely been reported. Therefore, we studied a noninvasive transdermal drug delivery system (TDDS) of ginger to bypass hepatic first pass metabolism, avoid gastrointestinal degradation and achieve long persistent release of effective compositions. After establishment of a HPLC analysis method of 6-gingerol, assays of 6-gingerol were performed to compare two kinds of ginger extracts. Then, the characteristics of transdermal delivery of 6-gingerol in TDDS were exhibited. The results showed that the contents of 6-gingerol in two kinds of ginger extracts were significantly different. The maximal delivery percentage of 6-gingerol across rat skin at 20 h was more than 40% in different TDDS formulations. TDDS may provide long-lasting delivery of ginger compounds.

Epidemiological studies have examined associations between dietary patterns and the risk of type 2 diabetes. However, information on dietary patterns and the risk of type 2 diabetes in Chinese populations is scarce. The aim of the present study was to identify dietary patterns and examine their association with incident hyperglycaemia in Nanjing, China. A community-based prospective cohort study. Dietary assessment was carried out using a validated eighty-seven-item FFQ. Dietary patterns were identified by exploratory factor analysis. Participants were categorized into tertiles of dietary factor score for each dietary pattern. The relationship between dietary patterns and hyperglycaemia risk was analysed using multivariable linear and Cox regression. Seven communities from two urban districts in Nanjing, China. A total of 2900 of Chinese local residents aged 30 years or above, free of hyperglycaemia and other serious diseases, who participated in the baseline survey from June to September 2007 were followed up 3 years later from June to September 2010 for the development of hyperglycaemia. Fasting blood samples were collected at both baseline and 3-year follow-up surveys. Hyperglycaemia was defined as fasting plasma glucose concentration of ≥6·1 mmol/l or already taking oral hyperglycaemia agents for treatment of type 2 diabetes. Five major dietary patterns were identified: (i) the 'condiments' pattern; (ii) the 'animal and plant protein' pattern; (iii) the 'healthy traditional' pattern; (iv) the 'fruits, eggs and juice' pattern; and (v) the 'alcohol, milk and tea' pattern. A total of 2093 (72·2 %) individuals completed the follow-up survey and the 3-year cumulative incidence of hyperglycaemia was 7·5 % (158/2093). A 1-unit increase in the score for the 'healthy traditional' pattern was associated with a decrease of 0·054 mmol/l in fasting plasma glucose (P=0·017), while a 1-unit increase in the 'fruits, eggs and juice' pattern score was associated with an increase of 0·050 mmol/l in fasting plasma glucose (P=0·023) by multivariable linear regression. For men, tertile 3 of the 'fruits, eggs and juice' pattern was associated with an 88 % greater risk (hazard ratio=1·88; 95 % CI 1·04, 3·54) of hyperglycaemia than tertile 1 of this pattern. Being in tertile 3 of the 'alcohol, milk and tea' pattern was associated with a 35 % greater risk (hazard ratio=1·35; 95 % CI 1·04, 2·16) relative to tertile 1 in women, while for the ''healthy traditional' pattern tertile 3 was associated with a 41 % lower risk (hazard ratio=0·59; 95 % CI 0·35, 0·99) compared with tertile 1. The 'condiments' and the 'animal and plant protein' patterns were not independently associated with hyperglycaemia. Our findings suggest that modifying dietary patterns could reduce hyperglycaemia incidence in the mainland Chinese adult population.

The supplementary comparison APMP.QM-S8: determination of mass fraction of benzoic acid, methyl paraben and n-butyl paraben in soy sauce was coordinated by the Health Sciences Authority, Singapore under the auspices of the Organic Analysis Working Group (OAWG) of the Comité Consultatif pour la Quantité de Matière (CCQM). Ten national metrology institutes (NMIs) or designated institutes (DIs) participated in the comparison. All the institutes participated in the comparison for benzoic acid, while six NMIs/DIs participated in the comparison for methyl paraben and n-butyl paraben. The comparison was designed to enable participating institutes to demonstrate their measurement capabilities in the determination of common preservatives in soy sauce, using procedure(s) that required simple sample preparation and selective detection in the mass fraction range of 50 to 1000 mg/kg. The demonstrated capabilities can be extended to include other polar food preservatives (e.g. sorbic acid, propionic acid and other alkyl benzoates) in water, aqueous-based beverages (e.g. fruit juices, tea extracts, sodas, sports drinks, etc) and aqueous-based condiments (e.g. vinegar, fish sauce, etc). Liquid--liquid extraction and/or dilution were applied, followed by instrumental analyses using LC-MS/MS, LC-MS, GC-MS (with or without derivatisation) or HPLC-DAD. Isotope dilution mass spectrometry was used for quantification, except in the case of a participating institute, where external calibration method was used for quantification of all three measurands. The assigned Supplementary Comparison Reference Values (SCRVs) were the medians of ten results for benzoic acid, six results for methyl paraben and six results for n-butyl paraben. Benzoic acid was assigned a SCRV of 154.55 mg/kg with a combined standard uncertainty of 0.94 mg/kg, methyl paraben was assigned a SCRV of 100.95 mg/kg with a combined standard uncertainty of 0.40 mg/kg, and n-butyl paraben was assigned a SCRV of 99.05 mg/kg with a combined standard uncertainty of 1.36 mg/kg. The k-factors for the estimation of the expanded uncertainties of the SCRVs were 2.26, 2.57 and 2.57, respectively. The degree of equivalence (with the SCRV) and its uncertainty were calculated for each result. All the participating institutes (except in one case for benzoic acid) were able to demonstrate or confirm their capabilities in the determination of polar food preservatives in water or aqueous-based beverages/condiments.

Bixa orellana (family Bixaceae) is a neotropical fast growing perennial tree of great agro-industrial value because its seeds have a high carotenoid content, mainly bixin. It has been used since pre-colonial times as a culinary colorant and spice, and for healing purposes. It is currently used as a natural pigment in the food, in pharmaceutical, and cosmetic industries, and it is commercially known as annatto. Recently, several studies have addressed the biological and medical properties of this natural pigment, both as potential source of new drugs or because its ingestion as a condiment or diet supplement may protect against several diseases. The most documented properties are anti-oxidative; but its anti-cancer, hypoglucemic, antibiotic and anti-inflammatory properties are also being studied. Bixin’s pathway elucidation and its regulation mechanisms are critical to improve the produce of this important carotenoid. Even though the bixin pathway has been established, the regulation of the genes involved in bixin production remains largely unknown. Our laboratory recently published B. orellana’s transcriptome and we have identified most of its MEP (methyl-D-erythritol 4-phosphate) and carotenoid pathway genes. Annatto is a potential source of new drugs and can be a valuable nutraceutical supplement. However, its nutritional and healing properties require further study. PMID:27708658

Ricin is a toxic ribosome inactivating protein (RIP-II) present in beans of the castor plant, Ricinus communis. Its potential as a biodefense threat has made the rapid, sensitive detection of ricin in food important to the U.S. Food and Drug Administration. Samples of juice, dairy products, soda, vegetables, bakery products, chocolate, and condiments were spiked with varying concentrations of ricin and analyzed using a 96-well format, electrochemiluminescence (ECL) immunoassay. Assay configurations included the use of a monoclonal capture antibody coupled with either a polyclonal or monoclonal detector antibody. The samples and detector antibodies were either added sequentially or in combination during the capture step. Using the polyclonal antibody, 0.04 ng/mL ricin was detected in analytical samples prepared from several beverages. By simultaneously incubating the sample with detector antibody, it was possible to decrease the assay time to a single 20 min incubation step with a limit of detection <10 ng/mL. Assays run according to this single incubation step exhibited a hook effect (decrease in signal at high concentrations of ricin), but because of the large signal-to-noise ratio associated with the ECL assay, the response remained above background and detectable. Thus, the ECL assay was uniquely suited for the screening of samples for ricin.

Benefits of dietary fiber go beyond its effect on chronic diseases associated with development. Consequently, the pattern of fiber intake has been considered an indicator for diet quality. Young adults are especially vulnerable to a food environment that drives an increase in chronic diseases linked to economic development. The aim of this work was to characterize patterns of fiber intake among university students. A cross-sectional study was conducted on a sample of 730 students enrolled at the University of Castilla-La Mancha (Spain), the University of Carthage (Tunisia), and Florida International University (USA). Mean age was 21.2. Food consumption was self-reported in two 24-h recalls. Mean dietary fiber intake was 17.8 g, not reaching the adequate intake. Contrary to expectations, American participants were the highest consumers ( p < 0.001), and also exhibited the highest BMI. Cereals, legumes, vegetables and fruit were the main food sources of fiber. Fiber from appetizers, prepared and precooked meals, sauces, spices and condiments accounted for 16.7% in American participants, 7.4% in Spanish participants and 2.6% in Tunisian participants. Total fiber intake increased with energy intake but did not depend on smoking habits and physical activity in any country. It is essential to improve consumers' interpretation of guidelines on fiber intake.

Cryogenics and its application with reference to spice grinding: a review.

Cryogenics is the study of very low temperature and its application on different materials including biological products. Cryogenics has numerous applications in space science, electronics, automobiles, the manufacturing industry, sports and musical instruments, biological science and agriculture, etc. Cryogenic freezing finds pivotal application in food, that is, spices and condiments. Although there is a wide range of cryogens to produce the desired low temperature, generally liquid nitrogen (LN₂) is used in food grinding. The application of low temperature shows a promising pathway to produce higher quality end product with higher flavor and volatile oil retention. Cryogenic grinders generally consist of precoolers and grinder with the cryogen distribution system. In such grinding systems, cryogens subject the raw material up to or lower than glass transition temperature before it is ground, thus eliminating much of the material and quality hassles of traditional grinding. At present, the capital investment including cryogen and handling costs escalate the final cost of the product. Thus, for large-scale production, a proper design to optimize and make it feasible is the need of the hour and understanding the behavior of different food materials at these low temperature conditions. This article reviews the scenario and application of cryogenics in different sectors, especially to spice grinding.

Commercial cultivars of garlic, a popular condiment, are sterile, making genetic studies and breeding of this plant challenging. However, recent fertility restoration has enabled advanced physiological and genetic research and hybridization in this important crop. Morphophysiological studies, combined with transcriptome and proteome analyses and quantitative PCR validation, enabled the identification of genes and specific processes involved in gametogenesis in fertile and male-sterile garlic genotypes. Both genotypes exhibit normal meiosis at early stages of anther development, but in the male-sterile plants, tapetal hypertrophy after microspore release leads to pollen degeneration. Transcriptome analysis and global gene-expression profiling showed that >16,000 genes are differentially expressed in the fertile vs. male-sterile developing flowers. Proteome analysis and quantitative comparison of 2D-gel protein maps revealed 36 significantly different protein spots, 9 of which were present only in the male-sterile genotype. Bioinformatic and quantitative PCR validation of 10 candidate genes exhibited significant expression differences between male-sterile and fertile flowers. A comparison of morphophysiological and molecular traits of fertile and male-sterile garlic flowers suggests that respiratory restrictions and/or non-regulated programmed cell death of the tapetum can lead to energy deficiency and consequent pollen abortion. Potential molecular markers for male fertility and sterility in garlic are proposed. PMID:25972879

Umami is a basic tastes, along with sweet, salty, bitter and sour, which is imparted by glutamate, one of the free amino acids in foods. Since its discovery of umami by a Japanese scientist in 1908, umami is now perceived globally a basic taste. Recent collaboration among chefs and researchers on traditional soup stocks showed a difference in taste profiles of Japanese soup stock 'dashi' and Western style soup stock. The free amino acids profile's in dashi and soup stock showed how Japanese have traditionally adopted a simple umami taste. The exchange of knowledge on cooking methods and diverse types of umami rich foods in different countries displays the blending of the culinary arts, food science and technology for healthy and tasty solutions. Since Japanese cuisine 'WASHOKU' was listed in the 'Intangible Heritage of UNESCO' in 2013, many people in the world now have great interest in Japanese cuisine. One of the unique characteristics of this cuisine is that 'dashi' is an indispensable material for cooking a variety of Japanese dishes. Many chefs from Europe, US and South America have come to Japan to learn Japanese cuisine in the last 10 years, and umami has become recognized as a common taste worldwide. Researchers and culinary professionals have begun to pay attention to the traditional seasonings and condiments rich in glutamate available throughout the world.

As many as 120 subjects, directed in 1984-1988 to the Diagnostic-Consultative Family Centre in Szczecin, were studied due to behaviour disorders or penal acts. Thirteen (10.8%) juveniles were exempted from further studies, since they were diagnosed to have mental deficiency or encephalopathy. The rest was studied by means of diagnostic criteria for behaviour disorders according to DSM-III-R. Those complying with the criteria made up a group with Behaviour Distemper Syndrome (BDS)--74 persons (55 boys and 19 girls), while the others formed a group holding Single Behaviour Distemper (SBD)--33 persons (21 boys and 12 girls). Two age subgroups, 7-14 and 15-17 years, were isolated from each of the groups. Use was made of own questionnaire to collect data concerning factors that might induce the revealed behaviour disorders. Groups BDS and SBD were compared with regard to the type and incidence rate of respective signs of behaviour disorders, according to criteria DSM-III-R, and also the age, sex as well as social background, living environment, and hereditary encumberance, course of pregnancy and delivery, former psychophysical development, use of condiments, somatic disorders actually evidenced, parental and school environmental atmosphere and that of peers of the studied group.

The use of essential oils as industrial food additives is notorious, like their medicinal properties. However, their use in household food spicing is for now limited. In this work, we have made a review to reveal the nutrigenomic actions exerted by their bioactive components, to promote awareness of their modulating gene expression ability and the potential that this implies. Also considered is how essential oils can be used as flavoring and seasoning after cooking and before consumption, such as diet components which can improve human health. Genetic mechanisms involved in the medicinal properties of essential oils for food use are identified from literature. These genetic mechanisms reveal nutrigenomic actions. Reviews on the medicinal properties of essential oils have been particularly considered. A wide diversity of nutrigenomic effects from essential oils useful potentially for food spicing is reviewed. General ideas are discussed about essential oils and their properties, such as anti-inflammatory, analgesic, immunomodulatory, anticancer, hepatoprotective, hypolipidemic, anti-diabetic, antioxidant, bone-reparation, anti-depressant and mitigatory for Alzheimer's disease. The essential oils for food use are potentially promoting health agents, and, therefore, worth using as flavoring and condiments. Becoming aware of the modulating gene expression actions from essential oils is important for understanding their potential for use in household dishes as spices to improve health.

Next-generation sequencing (NGS) produces numerous (often millions) short DNA sequence reads, typically varying between 25 and 400 bp in length, at a relatively low cost and in a short time. This revolutionary technology is being increasingly applied in whole-genome, transcriptome, epigenome and small RNA sequencing, molecular marker and gene discovery, comparative and evolutionary genomics, and association studies. The Brassica genus comprises some of the most agro-economically important crops, providing abundant vegetables, condiments, fodder, oil and medicinal products. Many Brassica species have undergone the process of polyploidization, which makes their genomes exceptionally complex and can create difficulties in genomics research. NGS injects new vigor into Brassica research, yet also faces specific challenges in the analysis of complex crop genomes and traits. In this article, we review the advantages and limitations of different NGS technologies and their applications and challenges, using Brassica as an advanced model system for agronomically important, polyploid crops. Specifically, we focus on the use of NGS for genome resequencing, transcriptome sequencing, development of single-nucleotide polymorphism markers, and identification of novel microRNAs and their targets. We present trends and advances in NGS technology in relation to Brassica crop improvement, with wide application for sophisticated genomics research into agronomically important polyploid crops.

Many Lamiaceae species are consumed in the Lebanese cuisine as food or condiment and are largely used in the traditional medicine of Lebanon to treat various diseases, including microbial infections. In this article we report the traditional medicinal uses of eleven Lamiaceae species: Coridothymus capitatus L., Lavandula stoechas L., Lavandula angustifolia Mill., Mentha spicata L. subsp. condensata, Origanum syriacum L., Rosmarinus officinalis, Salvia fruticosa Miller., Satureja cuneifolia Ten., Satureja thymbra L., Thymbra spicata L., and Vitex agnus-castus L. and study the chemical composition and antimicrobial activity of their essential oils (EOs). Our survey showed that Lamiaceae species are mainly used against gastrointestinal disorders and microbial infections. Chemical analysis of the EOs obtained from these plants allowed us to identify seventy-five compounds describing more than 90% of the relative composition of each EO. Essential oils with high amounts of thymol and carvacrol possessed the strongest antimicrobial activity. As expected, these two compounds demonstrated an interesting antifungal efficacy against the filamentous fungus T. rubrum. Our results confirmed that some of the Lamiaceae species used in Lebanon ethnopharmacological practices as antimicrobial agents do possess antibacterial and antifungal potential consistent with their use in alternative or complementary medicine.

Excessive salt intake is known to increase blood pressure and cardiovascular risk. Nevertheless, salt intake exceeds the recommendations in most countries. To face this problem, it is important to identify high consumers as well as the main contributors of salt intake. Overall, data of 2018 adults between 18 and 64 years were analysed to determine the main sources, socio-demographic and anthropometric correlates of salt intake. Dietary intake was assessed from 24-h-recalls, information on socio-demographic characteristics was obtained using a questionnaire and anthropometric data were measured. Salt intake was significantly higher in males than in females. There was a significant positive association between salt intake and body mass index. No significant differences in salt intake were observed for other variables including affluence, educational level, smoking status and physical activity. The main contributor to salt intake were condiments including table salt (32.6%), followed by cereals and cereal products (27.0%), meat and meat products (16.1%) and dairy products (14.0%). These results highlight that specific population groups need to be targeted by public health initiatives and that a reduction in salt intake can only be achieved in tandem with the food producers by the reduction of salt in processed foods.

Bangladesh has experienced rapid economic growth and achieved major health improvements in the past decade, but malnutrition rates remain high. A nationally representative study conducted in 2011 assessed the dietary habits of 841 children 24-59 months old, 1428 children 6-14 years old, and 1412 nonpregnant, nonlactating women. The study's objective was to assess dietary intakes of key micronutrients and the consumption pattern of potentially fortifiable foods, and then to model the potential impact of the fortification of key staple foods. The current intakes of several micronutrients-namely, iron, zinc, folate, vitamin A, and vitamin B12-were found to be insufficient to meet the needs of Bangladesh's children and women. The fortification of rice with iron and zinc and edible oil with vitamin A has the potential to fill a significant part of the nutrient gap, as these are consumed widely and in significant amounts. Wheat flour and sugar are not as promising food vehicles in the Bangladeshi context, as they were consumed by a smaller portion of the population and in smaller amounts. In conclusion, fortification of rice and oil is recommended to address the large gap in micronutrient intakes.

Ginger, which has been widely used for dietary condiment, has been reported to improve memory dysfunction in an animal model of Alzheimer's disease (AD). Recently, a few trials have been carried out to enhance the effects of ginger by improving the bioavailability of its relevant components via fermentation. Some reports have suggested that the fermented ginger has the ability to affect the AD in vitro systems; however, its anti-amnesic effects on an in vivo model still remain to be investigated. In the present study, we aimed to investigate the neuroprotective effects of ginger fermented with Schizosaccharomyces pombe (FG) in the in vivo models of AD. The neuroprotective effects were investigated by employing behavioral, western blotting, and immunohistochemical assays. The administration of FG improved recognition memory, impaired by scopolamine injection, than that of non-fermented ginger. In addition, FG ameliorated memory impairment in amyloid beta 1-42 (Aβ 1-42 ) plaque-injected mice via protecting neuronal cells in the CA3 area of the mouse hippocampus. Moreover, FG reinstated the pre- and postsynaptic protein levels decreased by Aβ 1-42 plaque-toxicity. Overall, these data suggest that FG attenuates memory impairment in Aβ 1-42 plaque-induced AD mice through inhibition of neuronal cell loss and synaptic disruption.

Horseradish ( Armoracia rusticana ) is a perennial crop and its root is used in condiments. Traditionally, horseradish root is used to treat bacterial infections of the respiratory tract and urinary bladder. The antiphlogistic activity, determined in activated primary human peripheral blood mononuclear cells (PBMC), was evaluated for an aqueous extract and its subfractions, separated by HPLC. Compound analysis was done by UHPLC-QToF/MS and GC-MS. The aqueous extract concentration-dependently inhibited the anti-inflammatory response to lipopolysaccharide (LPS) in terms of TNF- α release at ≥37  μ g/mL. Further, the cyclooxygenase as well as lipoxygenase pathway was blocked by the extract as demonstrated by inhibition of COX-2 protein expression and PGE 2 synthesis at ≥4  μ g/mL and leukotriene LTB4 release. Mechanistic studies revealed that inhibition of ERK1/2 and c-Jun activation preceded COX-2 suppression upon plant extract treatment in the presence of LPS. Chemical analysis identified target compounds with a medium polarity as relevant for the observed bioactivity. Importantly, allyl isothiocyanate, which is quite well known for its anti-inflammatory capacity and as the principal pungent constituent in horseradish roots, was not relevant for the observations. The results suggest that horseradish root exerts an antiphlogistic activity in human immune cells by regulation of the COX and LOX pathway via MAPK signalling.

Despite their abundance, Antarctic krill are underutilized because of numerous difficulties in their commercial processing. Ideally, fermentation technology can be applied to transform them into a popular condiment. In addition to the exploration of protease properties, the present study aimed to evaluate proteinase activity, pH, amino nitrogen, and histamine formation during fermentation at different temperatures and salt treatments. Even though the activity of Antarctic krill protease reached a maximum at 40 °C and pH 7, it was stable at 30 °C and pH 7-9. Among the metal ions tested, Ca 2+ , Mg 2+ and K + increased protease activity, in contrast to Zn 2+ and Cu 2+ . Within each treatment, the highest protease activity and amino nitrogen content, as well as the lowest histamine level, were observed on day 12 of fermentation. Treatment at 35 °C with 180 g kg -1 salt led to the production of maximum amino nitrogen (0.0352 g kg -1 ) and low histamine (≤0.0497 g kg -1 ). Krill paste fermented for 12 days at 35 °C with 180 g kg -1 salt exhibited the optimal quality and properties, suggesting an efficient method for fermentation of Antarctic krill and other aquatic resources. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

We examined the associations between sweets, sweetened and unsweetened beverages, and sugars and pancreatic cancer risk. We conducted a population-based case-control study (532 cases, 1,701 controls) and used multivariate logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (CI). Because associations were often different by sex, we present results for men and women combined and separately. Among men, greater intakes of total and specific sweets were associated with pancreatic cancer risk (total sweets: OR = 1.9, 95% CI: 1.0, 3.6; sweet condiments: OR = 1.9, 95% CI: 1.2, 3.1; chocolate candy: OR = 2.4, 95% CI: 1.1, 5.0; other mixed candy bars: OR = 3.3, 95% CI: 1.5, 7.3 for 1 + servings/day versus none/rarely). Sweets were not consistently associated with risk among women. Sweetened beverages were not associated with increased pancreatic cancer risk. In contrast, low-calorie soft drinks were associated with increased risk among men only; while other low-/non-caloric beverages (e.g., coffee, tea, and water) were unassociated with risk. Of the three sugars assessed (lactose, fructose, and sucrose), only the milk sugar lactose was associated with pancreatic cancer risk (OR = 2.0, 95% CI: 1.5, 2.7 comparing extreme quartiles). These results provide limited support for the hypothesis that sweets or sugars increase pancreatic cancer risk.

To determine the influence of 6-n-propylthiouracil (PROP) taster status and food adventurousness on liking of bitter, hot, and pungent foods. Self-reported survey of food likes/dislikes for 70 foods. Subjects were classified as tasters or nontasters of PROP using a standard screening procedure. By their response to a query regarding their perceived frequency of trying unfamiliar foods, subjects were characterized as being more or less adventurous. A convenience sample of 232 healthy adults, 18 to 55 years of age, was recruited from the local community. Statistical analyses Individual foods were grouped using Principal Component Analysis. Analysis of variance was used to assess differences in liking of food groups as a function of PROP status and food adventurousness. PROP tasters who were more food adventurous liked chili peppers and hot sauce, other pungent condiments, strong alcohol, and bitter fruits and vegetables more than tasters who were less food adventurous (P< or =.05-.001). Nontasters liked most foods, and food adventurousness had little influence on food liking for these individuals. Food adventurous PROP tasters liked a wide variety of strong-tasting foods, whereas tasters who were less food adventurous showed the classic dislike of bitter, hot, and pungent foods. Previous studies might have overestimated the influence of PROP taster status on rejection of strong-tasting foods by not distinguishing individuals by food adventurousness.

[New pharmacological activities of garlic and its constituents].

According to the recent pharmacological findings, garlic is a preventive rather than therapeutic. Epidemiological studies in China, Italy and USA showed the inverse relationship between stomach and colon cancer incidences and dietary garlic intake. Anti-carcinogenic activities of garlic and its constituents including sulfides and S-allyl cysteine, have been demonstrated using several animal models. Garlic preparations has been also shown to lower serum cholesterol and triglyceride levels, which are major risk factors of cardiovascular diseases, through inhibition of their bio-synthesis in the liver, and to inhibit oxidation of low density lipoprotein. Furthermore, in vitro and in vivo studies have revealed that aged garlic extract stimulated immune functions, such as proliferation of lymphocyte, cytokine release, NK activity and phagocytosis. More recently, aged garlic extract has been demonstrated to prolong life span of senescence accelerated mice and prevent brain atrophy. Manufacturing processes significantly affect chemical constituents in garlic preparations. Different forms contain different phytochemicals and may have different effects and toxicities. For example, aged garlic extract inhibited t-BuOOH-induced oxidation, whereas raw garlic stimulated the oxidation. Although garlic has been used as a condiment and folklore for a long time, it has been noted to cause adverse reactions, such as stomach ulcer and anemia. Among the garlic preparations, only aged garlic extract has been proven to be safe through toxicological studies. Thus, aged garlic extract could be the most promising garlic preparation for disease prevention.

The global shift towards diets high in sugar-sweetened beverages (SSBs) is linked to higher prevalence of obesity, diabetes and most other non-communicable diseases. In Colombia, one out of every two people was overweight or obese by 2010. This study estimates price-elasticities from a Quadratic Almost Ideal Demand System model, using the 2006-2007 Colombian Income and Expenditure survey. The food groups that were jointly considered were: unsweetened unflavored milks; coffee and tea; sugar sweetened beverages (SSBs); sweets and candies (including sugar); dairy products; meats and animal-based products; grains based staples; fruits and vegetables; and condiments and snacks. We take into account the high proportion of households not purchasing specific food and beverage groups (censored data) and endogeneity on both prices (as unit values) and total expenditure. Unhealthy beverages are price-elastic (-1.61 for SSBs) meaning that the change in consumption is proportionally larger with respect to a change in price. Also, there is a high complementarity among SSBs and major food groups (grains, meats and fruits and vegetables). In Colombia, the design of a meaningful tax to influence healthier diets is a next critical step. This study also shows that a tax of 20% on SSBs should prove to be effective, and can yield revenues of about 1% of the Colombian government's total annual fiscal revenue, which can potentially be directed towards public health promotion and investments.

Fermented soybean foods contain nutritional components including easily digestible peptides, cholesterol-free oils, minerals, and vitamins. Various fermented soybean foods have been developed and are consumed as flavoring condiments in Asian regions. While the quality of fermented soybean foods is largely affected by microorganisms that participate in the fermentation process, our knowledge about the microorganisms in soybean pastes manufactured in Northeast China is limited. The current study used a culture-independent barcoded pyrosequencing method targeting hypervariable V1/V2 regions of the 16S rRNA gene to evaluate Korean doenjang and soybean pastes prepared by the Hun Chinese (SPHC) and Korean minority (SPKM) populations in Northeast China. In total, 63399 high-quality sequences were derived from 16 soybean paste samples collected in Northeast China. Each bacterial species-level taxon of SPHC, SPKM, and Korean doenjang was clustered separately. Each paste contained representative bacterial species that could be distinguished from each other: Bacillus subtilis in SPKM, Tetragenococcus halophilus in SPHC, and Enterococcus durans in Korean doenjang. This is the 1st massive sequencing-based study analyzing microbial communities in soybean pastes manufactured in Northeast China, compared to Korean doenjang. Our results clearly showed that each soybean paste contained unique microbial communities that varied depending on the manufacturing process and location. © 2017 Institute of Food Technologists®.

To determine the contribution of total phenolic content (TPC) in glycation inhibitory activity of common tropical medicinal food and spices with potential antioxidative properties. In vitro glucose-bovine serum albumin (BSA) assay was used. Ethanolic extracts of ten common household condiments/herbs (Allium sativum, Zingiber officinale, Thymus vulgaris, Petroselinum crispum, Murraya koenigii Spreng, Mentha piperita L., Curcuma longa L., Allium cepa L., Allium fistulosum and Coriandrum sativum L.) were evaluated for antioxidative activity by 2,2-diphenyl-2-picrylhydrazyl (DPPH), and ferric reducing antioxidant power (FRAP) and the TPC, flavonoid and tannins content were determined. Findings showed good correlation between TPC/DPPH (r = 0.8), TPC/FRAP (r = 0.8), TPC/anti-glycation (r = 0.9), DPPH/anti-glycation (r = 0.6), FRAP/anti-glycation (r = 0.9), Flavonoid/anti-glycation (r = 0.7) and Tannins/anti-glycation (r = 0.8) and relatively fair correlation for TPC/Flavonoids (r = 0.5) and TPC/Tannins (r = 0.5). Results imply that these plants are potential sources of natural antioxidants which have free radical scavenging activity and might be used for reducing oxidative stress. The positive glycation inhibitory and antioxidative activities of these tropical herbs suggest a possible role in targeting ageing, diabetic complications and oxidative stress related diseases.

Capsicum species are not only cultivated as vegetable and condiment crops but are also incorporated into a number of medicinal preparations in the ancient literature around the world. 'Naga chilli' or 'Bhoot Jolokia' (Capsicum chinense Jacq.) is a chilli variety indigenous to the northeast region of India and has been recognized as the hottest chilli in the world. It has also been used conventionally in treating various human ailments since time immemorial by the indigenous people of the northeast India. Despite being an important crop of the northeast India, the information on the biology and cultivation of Naga chilli is very scanty and scattered. The present article reviews the scientific literature on above aspects with particular emphasis on identifying the key regional issues which need to be addressed urgently by the policy makers in order to harness its potential as an important source of capsaicinoids. Further, an attempt has been made to collate the potential of capsaicinoids in various ethnopharmacological applications such as pain therapy, body temperature regulation, anti-obesity treatments, anticancer therapy and as antioxidant and antimicrobial agent. We anticipate that this literature analysis of traditional medicinal uses and experimental trials of Capsicum using modern scientific approaches shall provide a basis for suggesting important areas where sincere research efforts are warranted to bridge the gap between traditional medicinal knowledge and modern biomedical knowledge.

Chunxiao, Xu; Hong, Liu

The use of plants for life support applications in space is appealing because of the multiple life support functions by the plants. Research on crops that were grown in the life support system to provide food and oxygen, remove carbon dioxide was begun from 1960. To select possible crops for research on the bioregenerative life support systems in China, criteria for the selection of potential crops were made, and selection of crops was carried out based on these criteria. The results showed that 14 crops including 4 food crops (wheat, rice, soybean and peanut) and 7 vegetables (Chinese cabbage, lettuce, radish, carrot, tomato, squash and pepper) won higher scores. Wheat ( Triticum aestivum L.), rice ( Oryza sativa L.), soybean ( Glycine max L.) and peanut ( Arachis hypogaea L.) are main food crops in China. Chinese cabbage ( Brassica campestris L. ssp. chinensis var. communis), lettuce ( Lactuca sativa L. var. longifolia Lam.), radish ( Raphanus sativus L.), carrot ( Daucus carota L. var. sativa DC.), tomato ( Lycopersicon escalentum L.), squash ( Cucurbita moschata Duch.) and pepper ( Capsicum frutescens L. var. longum Bailey) are 7 vegetables preferred by Chinese. Furthermore, coriander ( Coriandum sativum L.), welsh onion ( Allium fistulosum L. var. giganteum Makino) and garlic ( Allium sativum L.) were selected as condiments to improve the taste of space crew. To each crop species, several cultivars were selected for further research according to their agronomic characteristics.

Ginger is an economically important and valuable plant around the world. Ginger is used as a food, spice, condiment, medicine and ornament. There is available information on biochemical aspects of ginger, but few studies have been reported on its molecular aspects. The main objective of this review is to accumulate the available molecular marker information and its application in diverse ginger studies. This review article was prepared by combing material from published articles and our own research. Molecular markers allow the identification and characterization of plant genotypes through direct access to hereditary material. In crop species, molecular markers are applied in different aspects and are useful in breeding programs. In ginger, molecular markers are commonly used to identify genetic variation and classify the relatedness among varieties, accessions, and species. Consequently, it provides important input in determining resourceful management strategies for ginger improvement programs. Alternatively, a molecular marker could function as a harmonizing tool for documenting species. This review highlights the application of molecular markers (isozyme, RAPD, AFLP, SSR, ISSR and others such as RFLP, SCAR, NBS and SNP) in genetic diversity studies of ginger species. Some insights on the advantages of the markers are discussed. The detection of genetic variation among promising cultivars of ginger has significance for ginger improvement programs. This update of recent literature will help researchers and students select the appropriate molecular markers for ginger-related research.

Thymus quinquecostatus Celak is a species of thyme in China and it used as condiment and herbal medicine for a long time. To set up the quality evaluation of T. quinquecostatus , the response surface methodology (RSM) based on its 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity was introduced to optimize the extraction condition, and the main indicator components were found through an UPLC-LTQ-Orbitrap MS n method. The ethanol concentration, solid-liquid ratio, and extraction time on optimum conditions were 42.32%, 1:17.51, and 1.8 h, respectively. 35 components having 12 phenolic acids and 23 flavonoids were unambiguously or tentatively identified both positive and negative modes to employ for the comprehensive analysis in the optimum anti-oxidative part. A simple, reliable, and sensitive HPLC method was performed for the multi-component quantitative analysis of T. quinquecostatus using six characteristic and principal phenolic acids and flavonoids as reference compounds. Furthermore, the chemometrics methods (principal components analysis (PCA) and hierarchical clustering analysis (HCA)) appraised the growing areas and harvest time of this herb closely relative to the quality-controlled. This study provided full-scale qualitative and quantitative information for the quality evaluation of T. quinquecostatus , which would be a valuable reference for further study and development of this herb and related laid the foundation of further study on its pharmacological efficacy.

The prevalence of micronutrient deficiencies in Cambodia is among the highest in Southeast Asia. Fortification of staple foods and condiments is considered to be one of the most cost-effective strategies for addressing micronutrient deficiencies at the population level. The Government of Cambodia has recognized the importance of food fortification as one strategy for improving the nutrition security of its population. This paper describes efforts under way in Cambodia for the fortification of fish sauce, soy sauce, and vegetable oil. Data were compiled from a stability test of Cambodian fish sauces fortified with sodium iron ethylenediaminetetraacetate (NaFeEDTA); analysis of fortified vegetable oils in the Cambodian market; a Knowledge, Attitudes, and Practices (KAP) study of fortified products; and food fortification program monitoring documents. At different levels of fortification of fish sauce with NaFeEDTA, sedimentation and precipitation were observed. This was taken into consideration in the government-issued standards for the fortification of fish sauce. All major brands of vegetable oil found in markets at the village and provincial levels are imported, and most are nonfortified. Fish sauce, soy sauce, and vegetable oil are widely consumed throughout Cambodia and are readily available in provincial and village markets. Together with an effective regulatory monitoring system, the government can guarantee that these commodities, whether locally produced or imported, are adequately fortified. A communications campaign would be worthwhile, once fortified commodities are available, as the KAP study found that Cambodians had a positive perception of fortified sauces.

To examine changes in the Na content of lunch/dinner menu offerings at eight of the leading fast-food restaurants in the USA between 1997/1998 and 2009/2010. Menu offerings and nutrient composition information for the menu items were obtained from archival versions of the University of Minnesota Nutrition Coordinating Center (NCC) Food and Nutrient Database. Nutrient composition information for lunch/dinner menu items sold by the fast-food restaurants included in the present study was updated in the database biannually. Menus were analysed for changes in mean Na content of all menu offerings (except beverages) and specific categories of menu items among all restaurants and for each individual restaurant. Lunch/dinner food menu of eight leading US fast-food restaurants. Between 1997/1998 and 2009/2010 the mean Na content of menu offerings across the eight restaurants increased by 23·4 %. Examining specific food categories, mean Na content of entrées by increased 17·2 % and that of condiments increased by 26·1 %. Only side dishes showed a decrease of 6·6 %. None of the restaurants examined had a decrease in Na across the lunch/dinner menu offerings over the 14 years examined. Results suggest that over the time period studied there has been no meaningful reduction in the Na content of lunch/dinner menu offerings at the leading fast-food restaurants examined in the present study.

The processed food sector in low- and middle-income countries has grown rapidly. Little is understood about its effect on obesity. Using data from 14,976 participants aged two and older in the 2011 China Health and Nutrition Survey, this paper examines patterns of processed food consumption and their impacts on obesity while considering the endogeneity of those who purchase processed foods. A major assumption of our analysis of the impact of processed foods on overweight and obesity was that the consumption of processed foods is endogenous due to their accessibility and urbanicity levels. The results show that 74.5% of participants consumed processed foods, excluding edible oils and other condiments; 28.5% of participants' total daily energy intake (EI) was from processed foods. Children and teenagers in megacities had the highest proportion of EI (40.2%) from processed foods. People who lived in megacities or highly urbanized neighborhoods with higher incomes and educational achievement consumed more processed foods. When controlling for endogeneity, only the body mass index (BMI) and risk of being overweight of children ages two to eighteen are adversely associated with processed foods (+4.97 BMI units, 95% confidence interval (CI): 1.66-8.28; odds ratio (OR) = 3.63, 95% CI: 1.45-9.13). Processed food purchases represent less than a third of current Chinese food purchases. However, processed food purchases are growing at the rate of 50% per year, and we must begin to understand the implications for the future.

Piper has been used for long timelike condiment and food, but also in traditional medicine around of the world. This work resumes the available and up to date work done on members of the Piperaceae family and their uses for therapeutic purposes. Information on Piper genus was gathered via internet using scientific databases such as Scirus, Google Scholar, CAB-abstracts, MedlinePlus, Pubmed, SciFinder, Scopus and Web of Science. The largeleafed perennial plant Piper is used for its spicy aromatic scent and flavor. It has an important presence in the cuisine of different cultures. Another quality of these plants is their known medicinal properties. It has been used as emollient, antirheumatic, diuretic, stimulant, abortifacient, anti-inflammatory, antibacterial, antifungal and antidermatophytic. A survey of the literature shows that the genus Piper is mainly known for its alkaloids with cytotoxic, chemopreventive, antimetastatic and antitumor properties in several types of cancer. Studies of its alkaloids highlight the existence of various potential leads to develop new anti-cancer agents. Modern pharmacology studies have demonstrated that its crude extracts and active compounds possess wide pharmacological activities, especially asantioxidant, anti-depressive, hepatoprotective, antimicrobial, anti-obesity, neuropharmacological, to treat cognitive disorders, anti-hyperlipidemic, anti-feedant, cardioactive, immuno-enhancing, and anti-inflamatory. All this evidence supporting its traditional uses. This review summarizes the up-to-date and comprehensive information concerning the botany, traditional use, phytochemistry and pharmacology of Piper together with its toxicology, and discusses the possible trend and scope for further research on Piper in the future.

Oral cancer is the second most common cancer in women and the third most common in men in Pakistan. Tobacco is smoked and chewed extensively in Pakistan. Paan is a quid of piper betel leaf that contains areca nut, lime, condiment, sweeteners, and sometimes tobacco, which is also used extensively. We did this study to clarify the independent association of paan and oral cancer. Between July 1996 and March 1998, we recruited biopsy-proven, primary cases of oral squamous-cell carcinoma, from 3 tertiary teaching centers in Karachi, Pakistan, and controls pair-matched for age, gender, hospital and time of occurrence, excluding persons with a past or present history of any malignancy. There were 79 cases and 149 controls. Approximately 68% of the cases were men, 49 years old on average, the youngest being 22 years old and the eldest 80. People with oral submucous fibrosis were 19.1 times more likely to develop oral cancer than those without it, after adjusting for other risk factors. People using paan without tobacco were 9.9 times, those using paan with tobacco 8.4 times, more likely to develop oral cancer as compared with non-users, after adjustment for other covariates. This study identifies an independent effect of paan without tobacco in the causation of oral cancer. Its findings may be of significance in South Asian communities where paan is used, and among health-care providers who treat persons from South Asia.

Bariatric surgery is an effective tool in treating severe obesity. It provides significant weight loss in morbidly obese people accompanied by improvement in comorbidities and quality of life. To investigate the weight loss outcomes in the first month after bariatric surgery after introduction of solids three weeks postoperatively. Thirty-two charts of patients who underwent bariatric surgery were analyzed at a private nutritional clinic in São Sebastião do Paraíso, MG, Brazil; 93,75% of the subjects underwent Roux-en-Y gastric bypass, and 6,25% vertical gastrectomy. The subjects were 16 to 60 years. A body mass index of 30 to 69 Kg/m2 was obtained. Patients were instructed to eat small amounts several times a day, eat slowly, chew foods thoroughly, substitute sugar for sweetener, stop drinking gassy beverages, set the utensils down in between meals, drink only in between meals, avoid processed condiments and fried and greasy foods. In the first month after surgery, the mean weight loss was 9,7% and the percentage of excess weight loss was 23,9%. It was found that there was significant statistical difference in relation to initial and final weight (p=0,00; p<0,05). This protocol provides more freedom of choice in health care once one does not have to go on food intake modifications for more than three weeks; more nutritional guidelines is followed and prospective weight loss is presented.

The diarrheal toxin encoding genes cytK-1, cytK-2, hblA, hblC, and hblD were present in 0%, 91% 15%, 34% and 35% of B. cereus isolates, respectively. 9% of them harbored the emetic toxin genetic determinant, cesB. This study is the first to identify the AEFB of Yanyanku and Ikpiru to species level and perform a safety evaluation based on toxin gene detections. We further suggest, that the gyrA gene can be used for differentiating the closely related species Bacillus pumilus and B. safensis. Copyright © 2013 Elsevier B.V. All rights reserved.

Shrimp paste is a type of condiments with high nutritional value. However, the flavors of shrimp paste, particularly the non-uniformity flavors, have limited its application in food processing. In order to identify the characteristic flavor compounds in Chinese traditional shrimp pastes, five kinds of typical commercial products were evaluated in this study. The differences in the volatile composition of the five products were investigated. Solid phase micro-extraction method was employed to extract the volatile compounds. GC-MS and electronic nose were applied to identify the compounds, and the data were analyzed using principal component analysis (PCA). A total of 62 volatile compounds were identified, including 8 alcohols, 7 aldehydes, 3 ketones, 7 ethers, 7 acids, 3 esters, 6 hydrocarbons, 12 pyrazines, 2 phenols, and 7 other compounds. The typical volatile compounds contributing to the flavor of shrimp paste were found as follows: dimethyl disulfide, dimethyl tetrasulfide, dimethyl trisulfide, 2, 3, 5-trimethyl-6-ethyl pyrazine, ethyl-2, 5-dimethyl-pyrazine, phenol and indole. Propanoic acid, butanoic acid, furans, and 2-hydroxy-3-pentanone caused unpleasant odors, such as pungent and rancid odors. Principal component analysis showed that the content of volatile compounds varied depending on the processing conditions and shrimp species. These results indicated that the combinations of multiple analysis and identification methods could make up the limitations of a single method, enhance the accuracy of identification, and provide useful information for sensory research and product development.

Diabetic patients may find it difficult to achieve recommended nutrient intakes embedded within dietary guidelines. The objective of this analysis was to document total sodium, saturated fat, and added sugar intake as well as the main food sources of these nutrients in Canadian adults with type 2 diabetes before and after an intervention focused on healthy eating. Participants were enrolled in a single-arm dietary intervention trial designed to improve glycemic control and adherence to dietary recommendations. A 4-week menu plan and recipes were provided for participants along with a 6-week educational curriculum. Three repeated 24-h dietary recalls were collected at baseline and 3 months. Food sources of sodium, saturated fat, and added sugar were a secondary outcome derived from the dietary recalls. After 3 months, there was a reduction (p < 0.05) in sodium intake of 561 mg/day, which was mainly due to reduced consumption of processed meats, soups, and condiments. Significantly lower intake of processed meat contributed to -2.9 g/day saturated fat intake (p < 0.1) while added sugar intake declined by 7 g/day (p < 0.1), which was due to lower consumption of baked goods/desserts and chocolate (both p < 0.05). The intervention was beneficial for type 2 diabetes patients in terms of changing dietary habits. However, the majority of the participants still exceeded the dietary guidelines for sodium and saturated fat. In addition to the efforts of individuals and their healthcare providers, strategies to increase the nutritional quality of prepared foods could provide widespread benefits.

When, how much and what foods are eaten are related to total daily food intake.

Intake in the morning is associated with a reduction in the total intake for the day, while intake at night is associated with greater overall daily intake. These associations are macronutrient specific, with morning carbohydrate intake associated with reduced daily carbohydrate intake, morning fat intake associated with reduced daily fat intake and morning protein intake associated with reduced daily protein intake. Since different types of foods contain differing proportions of macronutrients, the present study investigated the associations of different types of foods ingested at various times of day with total daily and macronutrient intakes. The intakes of 388 male and 621 female free-living individuals reported in 7 d diet diaries were reanalysed. The intakes of twenty-four different types of foods and seven different drinks occurring during the morning (04.00-10.29 hours), afternoon (10.30-16.59 hours) and evening (17.00-02.00 hours) were identified and related to overall daily intakes. Dairy foods, ice cream, beef, other meats, potatoes, pastry, nuts, chips and snacks, condiments, alcohol and soda were significantly associated with higher total intake over the day, while fruit, soup, breakfast cereal, pasta, pizza, water, coffee/tea and diet soda were either not associated or were associated with lower overall intake. Dietary energy density appeared to mediate the associations between particular foods and beverages and overall energy intake. This suggests that eating low-density foods in the morning and avoiding high-density foods at night might aid in reducing overall intake and may be useful in dietary interventions for overweight and obesity.

Background We compare traditional knowledge and use of wild edible plants in six rural regions of the northwest of the Iberian Peninsula as follows: Campoo, Picos de Europa, Piloña, Sanabria and Caurel in Spain and Parque Natural de Montesinho in Portugal. Methods Data on the use of 97 species were collected through informed consent semi-structured interviews with local informants. A semi-quantitative approach was used to document the relative importance of each species and to indicate differences in selection criteria for consuming wild food species in the regions studied. Results and discussion The most significant species include many wild berries and nuts (e.g. Castanea sativa, Rubus ulmifolius, Fragaria vesca) and the most popular species in each food-category (e.g. fruits or herbs used to prepare liqueurs such as Prunus spinosa, vegetables such as Rumex acetosa, condiments such as Origanum vulgare, or plants used to prepare herbal teas such as Chamaemelum nobile). The most important species in the study area as a whole are consumed at five or all six of the survey sites. Conclusion Social, economic and cultural factors, such as poor communications, fads and direct contact with nature in everyday life should be taken into account in determining why some wild foods and traditional vegetables have been consumed, but others not. They may be even more important than biological factors such as richness and abundance of wild edible flora. Although most are no longer consumed, demand is growing for those regarded as local specialties that reflect regional identity. PMID:17555572

Goshtaba is a restructured meat product of Kashmiri wazwan prepared from meat emulsion with added fat (20 %), salt, spices and condiments and cooked in the curd. The present study was undertaken for the development of low fat goshtaba with the addition of xanthan gum as a fat replacer and was evaluated for proximate composition, pH, colour, lipid and protein oxidation, texture, microstructure and sensory properties. Low fat goshtaba formulations containing xanthan gum were higher in protein and moisture contents but, lower in fat content and pH value than the high fat control (p < 0.05). Colour evaluation revealed that high fat goshtaba had significantly higher L* value, but lower a* value than its low fat counterparts (p < 0.05). The significant decrease of TBARS values, protein carbonyls and loss of protein sulphydryl groups in low fat goshtaba formulations reflects the potential antioxidant activity of xanthan gum (p < 0.05). Hardness was significantly higher in high fat control but, cohesiveness, gumminess, and chewiness did not show any significant difference. Springiness increased with the increasing concentration of xanthan gum (0.5-1.5 %) and was higher in low fat product containing 1.5 % xanthan gum. SEM results indicate that xanthan gum lead to formation of an additional gel network which holds more water. Sensory evaluation revealed that goshtaba product with 0.5 % xanthan gum had quality characteristics that were similar to the control product containing 20 % fat.

Ten important plant parts routinely used in South Indian ethnic food preparation as spices and condiments were investigated for their potential antidyslipidemic properties. The aim of the study was to characterize the biochemical properties of the polyherbal formulation (nutritional supplement) and evaluate its use to control dyslipidemia in patients. Phytochemical evaluation, in vitro α-amylase inhibitory assay, and high performance thin layer chromatography (HPTLC) fingerprinting were carried out with alcoholic extracts of all 10 individual plants and with the nutritional supplement. Investigation in human volunteers was conducted to evaluate the effect on dyslipidemia as measured by serum lipid biomarkers. Sixty-five volunteers were recruited for this study. Biomarker values at baseline and at 6th visit (end of review, 8/9 months) were compared to assess the usefulness of the nutritional supplement in the normalization of lipid biomarkers. In the qualitative analysis of metabolites, the results revealed the presence of various bioactive primary and secondary metabolites that might be responsible for their medicinal attributes. In human volunteers, after supplement intake along with standard therapy, we observed significant decrease in serum cholesterol, triglyceride, low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) levels. High-density lipoprotein (HDL) level did not change in test patient volunteers. Reductions in hemoglobin A1C (HBA1C) and postprandial blood sugar levels were observed; the difference was not statistically significant. We believe that the polyherbal formulation of 10 medicinal plants has potent antidyslipidemic activity. Our results contribute for the first time toward documentation of augmented dyslipidemia control by use of the formulation.

Ethnobotany is an adequate tool to identify the most import wild edible plants used by local people and to develop strategies for its sustainable use and policy making. This research records the wild edible plants used by the inhabitants of the Sierra la Laguna Biosphere Reserve, in Mexico, and identified priority species for sustainable development. The employed quantitative approach included the application of a food-oriented index named Food Significance Index (FSI), which integrated cultural, agricultural and food parameters; moreover, it used multivariate analysis to identify priority edible species for use and/or conservation. Fifty taxa were identified as the most important wild edible plants in the reserve, integrated into five priority groups. Foods in priority group 1 had the highest culinary diversity by grouping three fruits (Ficus petiolaris, Stenocereus thurberi, and Cyrtocarpa edulis), one almond-like seed (Cnidoscolus maculatus), one vegetable (Matelea cordifolia), and one condiment (Capsicum annuum). Priority groups 2-5 were selective for one or two types of food, such as fruits, teas, or seeds. Since group 1 was the most diverse, the FSI and the employed strategy permitted to identify the priority wild edible plant species with the highest potential for food security. The selected six species should be included in the future management program of the reserve as the priority wild edible plants to develop strategies for conservation, sustainable use, and improvement of the local population income. General policies to manage the selected six species are outlined. Copyright © 2017 Elsevier Ltd. All rights reserved.

Shimatogarashi (Capsicum frutescens) is a typical chili pepper domesticated in southern Japan. Important traits of Shimatogarashi peppers, such as color; proportion of organic acids, capsaicinoids, and aromatic compounds; and antioxidant activity in three stages of maturity (green (immature), orange (turning), and red (mature) stages) were characterized. The results indicated that the concentration of organic acids, including ascorbic, citric, and malic acid, increased during ripening. In addition, the amount of capsaicinoids, which are responsible for the pungent taste of chili peppers, increased as the fruit matured to the orange and red stages. The volatile compound profile of Shimatogarashi was dominated by the presence of esters, which mainly contributed to fruity notes. The total amount of volatile compounds analyzed by gas chromatography-headspace solid-phase microextraction (GC-HS-SPME), especially esters, decreased as the fruit changed in color from green to red. This was in contrast to the amount of terpenoids, especially limonene, which increased at the red stage, denoting a change in flavor from fruity to a more citrus-like aroma. Based on the total phenolic content (TPC), the oxygen radical absorbance capacity (ORAC) and the diphenylpicrylhydrazyl (DPPH) free radical method, the antioxidant capacity of Shimatogarashi showed an increase at the mature red stage. However, while the red stage showed higher pungency and antioxidant capacity as well as an attractive color, the results of aromatic compound analysis revealed that the immature green stage had the advantages of having pleasant fruity smell, making it suitable for use in condiments.

Background Within the past decade there has been increasing attention to the role of fast food in the American diet, including a rise in legislative and media-based efforts that address the healthfulness of fast food. However, no studies have been undertaken to evaluate changes in the energy content of fast-food chain restaurant menu items during this period. Purpose To examine changes in the energy content of lunch/dinner menu offerings at eight of the leading fast-food chain restaurants in the U.S. between 1997/1998 and 2009/2010. Methods Menu offerings and nutrient composition information were obtained from archival versions of the University of Minnesota Nutrition Coordinating Center Food and Nutrient Database. Nutrient composition information for items was updated biannually. Changes in median energy content of all lunch/dinner menu offerings and specific categories of menu items among all restaurants and for individual restaurants were examined. Data were collected between 1997 and 2010 and analysis was conducted in 2011. Results Spanning 1997/1998 and 2009/2010, the number of lunch/dinner menu items offered by the restaurants in the study increased by 53%. Across all menu items, the median energy content remained relatively stable over the study period. Examining specific food categories, the median energy content of desserts and condiments increased, the energy content of side items decreased, and energy content of entrees and drinks remained level. Conclusions While large increases in the number of menu items were observed, there have been few changes in the energy content of menu offerings at the leading fast-food chain restaurants examined in this study.

Vinegar is a traditional fermented condiment, and the microbial diversity of DaQu makes the quality of vinegar products. Recently, turbidity spoilage of vinegar sharply tampered with the quality of vinegar. In this study, the relation between the microbial diversity of DaQu and turbidity spoilage of vinegar was analyzed by plating technique, PCR-denaturing gradient gel electrophoresis (DGGE), and high-performance liquid chromatography (HPLC). The 16S rRNA sequencing and DGGE analysis indicated that Bacillus (Bacillus subtilis, Bacillus amyloliquefaciens, and Bacillus thuringiensis) and Lactobacillus (including Lactobacillus acidipiscis and Lactobacillus pobuzihii) species were the dominant contaminants in vinegar products. Meanwhile, DGGE analysis showed that the dominant bacteria in DaQu belonged to genera Bacillus, Lactobacillus, Pseudomonas, Weissella, Saccharopolyspora, Enterobacter, and Pantoea. However, only two yeast species (Pichia kudriavzevii and Saccharomycopsis fibuligera) and seven mold species including Aspergillus oryzae, Aspergillus niger, Aspergillus candidus, Rhizopus microspores, Eurotium herbariorum, Absidia corymbifera, and Eupenicillium javanicum were detected in the DaQu. The population level of fungi was below 5 log CFU/g in DaQu. The chemical and physical properties of vinegar and sediments were also determined. On the basis of a combined microbial diversity-chemical analysis, we demonstrated that turbidity spoilage of vinegar was a result of cooperation among the low population level and abundance of fungal species in DaQu, the suitable climate conditions, and the contaminants in vinegar. This is the first report to analyze the relation between the microbial diversity of DaQu and turbidity spoilage of vinegar.

Role of life-style and dietary habits in risk of cancer among seventh-day adventists.

Phillips, R L

The Seventh-Day Adventist population abstains from smoking and drinking; about 50% follow a lacto-ovo-vegetarian diet; and most avoid the use of coffee, tea, hot condiments, and spices. Existing data on cancer mortality in Seventh-Day Adventists clearly document mortality rates that are 50 to 70% of general population rates for most cancer sites that are unrelated to smoking and drinking. Several approaches to determining whether this reduced risk is due to the unique Seventh-Day Adventist life-style or selective factors related to who choses to become and remain a Seventh-Day Adventist are described. A comparison of the mortality experience of Seventh-Day Adventist and non-Seventh-Day Adventist physicians shows equal cancer mortality, which is consistent with the hypothesis that the apparent reduced risk of cancer death in all Adventists may be due to selective factors. However, the results of a small case-control study of colon and breast cancer among Adventists show statistically significant relative risks for colon cancer of 2.8 for past use of meat. For current food use, the significant relative risks are 2.3 for beef, 2.7 for lamb, and 2.1 for a combined group og highly saturated fat foods. This strongly suggests that the lacto-ovo-vegetarian diet may protect against colon cancer. However, the evidence linking diet to breast cancer is less clear. Because of the marked variability in dietary habits within the Seventh-Day Adventist population, they will be a productive group for further study of diet and cancer.

There has been no data on population based dietary patterns during the Ramadan fasting month. The purpose of this study was to detect Ramadan major dietary patterns among those who fast in Tehran. This cross-sectional study included 600 subjects, aged 18-65 with body mass index (BMI) of 18.5-40, who had decided to fast during Ramadan. Anthropometric measurements, usual physical activity level and educational status were collected two weeks before Ramadan. Information on Ramadan dietary intakes was obtained using a food frequency questionnaire and factor analysis was used to identify major dietary patterns. We identified four major dietary patterns: 1) Western-like pattern; high in fast foods, salty snacks, nuts, potato, fish, poultry, chocolates, juices; 2) high cholesterol and high sweet junk food pattern; high in pickles, sweets and condiments, butter and cream, canned fish, visceral meats and eggs; 3) Mediterranean-like pattern; high in vegetables, olive oil, dates, dairy, dried fruits, fruits, red meats, tea and coffee and 4) Ramadan-style pattern; large consumption of Halim, soups, porridges, legumes and whole grains, soft drinks, Zoolbia and Bamieh. Age was positively and inversely associated with Mediterranean-like (P = 0.003; r = 0.17) and Ramadan style (P = 0.1; r = -0.13) dietary pattern, respectively. Pre-Ramadan physical activity level was associated with a Mediterranean-like dietary pattern (P < 0.0001; r = 0.20). This study showed a Ramadan-specific dietary pattern has unique characteristics, which has not yet been identified as a model of dietary pattern. Also, among identified dietary patterns, Mediterranean-like was the healthiest.

Petroselinum crispum (English parsley) is a common herb of the Apiaceae family that is cultivated throughout the world and is widely used as a seasoning condiment. Studies have shown its potential as a medicinal herb. In this study, P. crispum leaf and stem extracts were evaluated for their antioxidant properties, protection against DNA damage in normal 3T3-L1 cells, and the inhibition of proliferation and migration of the MCF-7 cells. The dichloromethane extract of P. crispum exhibited the highest phenolic content (42.31 ± 0.50 mg GAE g(-1) ) and ferric reducing ability (0.360 ± 0.009 mmol g(-1) ) of the various extractions performed. The extract showed DPPH radical scavenging activity with an IC50 value of 3310.0 ± 80.5 µg mL(-1) . Mouse fibroblasts (3T3-L1) pre-treated with 400 µg mL(-1) of the extract showed 50.9% protection against H2 O2 -induced DNA damage, suggesting its potential in cancer prevention. The extract (300 µg mL(-1) ) inhibited H2 O2 -induced MCF-7 cell migration by 41% ± 4%. As cell migration is necessary for metastasis of cancer cells, inhibition of migration is an indication of protection against metastasis. Petroselinum crispum has health-promoting properties with the potential to prevent oxidative stress-related diseases and can be developed into functional food. © 2015 The Authors.

Vitamin and mineral premix is one of the most significant recurring input costs for large-scale food fortification programs. A number of barriers exist to procuring adequate quality premix, including accessing suppliers, volatile prices for premix, lack of quality assurance and monitoring of delivered products, and lack of funds to purchase premix. To develop and test a model to procure premix through a transparent and efficient process in which an adequate level of quality is guaranteed and a financial mechanism is in place to support countries or specific target groups when there are insufficient resources to cover the cost of premix. Efforts focused on premixes used to fortify flour, such as wheat or maize (iron, zinc, B vitamins, and vitamin A), edible oils (vitamins A and D), and other food vehicles, such as fortified complementary foods, complementary food supplements, and condiments. A premix procurement model was set up with three distinct components: a certification process that establishes industry-wide standards and guidelines for premix, a procurement facility that makes premix more accessible to countries and private industry engaged in fortification, and a credit facility mechanism that helps projects finance premix purchases. After three years of operation, 15 premix suppliers and 29 micronutrient manufacturers have been certified, and more than US$23 million worth of premix that met quality standards has been supplied in 34 countries in Africa, Central and Southern Asia, and Eastern Europe, reaching an estimated 242 million consumers. The Premix Facility demonstrated its effectiveness in ensuring access to high-quality premixes, therefore enabling the success of various fortification programs.

2012-02-01

The 'Smart Choices' programme was an industry-driven, front-of-package (FOP) nutritional labelling system introduced in the USA in August 2009, ostensibly to help consumers select healthier options during food shopping. Its nutritional criteria were developed by members of the food industry in collaboration with nutrition and public health experts and government officials. The aim of the present study was to test the extent to which products labelled as 'Smart Choices' could be classified as healthy choices on the basis of the Nutrient Profile Model (NPM), a non-industry-developed, validated nutritional standard. A total of 100 packaged products that qualified for a 'Smart Choices' designation were sampled from eight food and beverage categories. All products were evaluated using the NPM method. In all, 64 % of the products deemed 'Smart Choices' did not meet the NPM standard for a healthy product. Within each 'Smart Choices' category, 0 % of condiments, 8·70 % of fats and oils, 15·63 % of cereals and 31·58 % of snacks and sweets met NPM thresholds. All sampled soups, beverages, desserts and grains deemed 'Smart Choices' were considered healthy according to the NPM standard. The 'Smart Choices' programme is an example of industries' attempts at self-regulation. More than 60 % of foods that received the 'Smart Choices' label did not meet standard nutritional criteria for a 'healthy' food choice, suggesting that industries' involvement in designing labelling systems should be scrutinized. The NPM system may be a good option as the basis for establishing FOP labelling criteria, although more comparisons with other systems are needed.

Despite wild food plants' potential nutritional and economic value, their knowledge and consumption is quickly decreasing throughout the world. We examine how the consideration that a wild plant use is within the cultural tradition of a given area relates to its consumption by analysing 1) current perception and 2) past and present use of six wild plants' food-uses, of which only three are locally perceived as being part of the local tradition. Research was conducted in Gorbeialdea, an area in the Basque Country with a clearly marked Basque identity opposed to the Spanish identity. Overall, there is a clear decrease in the knowledge and consumption of the selected uses and especially of the three uses acquired from local sources (i.e., the consumption of the raw leaves of Fagus sylvatica and Rumex acetosa and of the fruits of Pyrus cordata). The trend is likely driven by the disappearance of the traditional agrarian lifestyle. Among the uses not acquired from local sources, the use recently adopted from another Basque-speaking area (i.e., macerating the fruits of Prunus spinosa to elaborate a liqueur) is now considered part of the local tradition by young generations, whereas the use acquired from southern Spanish migrants (i.e., using Laurus nobilis leaves as condiments) is not. While lifestyle changes largely explain overall trends in wild edibles consumption, other cultural aspects -in our case study the stigmatization of a given source of information associated to cultural identity- might help shape which new uses of wild plants become embedded in local traditions.

Schlepütz, Tino; Büchs, Jochen

2014-04-01

As an important food preservative and condiment, vinegar is widely produced in industry by submerged acetic acid bacteria cultures. Although vinegar production is established on the large scale, up to now suitable microscale cultivation methods, e.g. using microtiter plates, are missing to enable high-throughput cultivation and to optimize fermentation conditions. In order to minimize evaporation losses of ethanol and acetic acid in a 48-well microtiter plate during vinegar production a new custom-made lid was developed. A diffusion model was used to calculate the dimensions of a hole in the lid to guarantee a suitable oxygen supply and level of ventilation. Reference fermentation was conducted in a 9-L bioreactor to enable the calculation of the proper cultivation conditions in the microtiter plate. The minimum dissolved oxygen tensions in the microtiter plate were between 7.5% and 23% of air saturation and in the same range as in the 9-L bioreactor. Evaporation losses of ethanol and acetic acid were less than 5% after 47 h and considerably reduced compared to those of microtiter plate fermentations with a conventional gas-permeable seal. Furthermore, cultivation times in the microtiter plate were with about 40 h as long as in the 9-L bioreactor. In conclusion, microtiter plate cultivations with the new custom-made lid provide a platform for high-throughput studies on vinegar production. Results are comparable to those in the 9-L bioreactor.

Raphanus sativus seeds are used as condiment and to treat hypogonadism, various ailments of liver and kidneys. The aim of this study was to evaluate the potential protective effects of methanol extract of R. sativus seeds (RSME) against hypogonadism induced with carbon tetrachloride (CCl 4 ) in Sprague-Dawley male rats. Thirty six rats were divided in to six groups with six animals in each. Animals of Group I were control and treated with saline, Group II, III and IV were given orally CCl 4 (1 ml/kg bw; 10% in corn oil). Rats of Group III and IV were also simultaneously given RSME at 100 mg/kg bw and 200 mg/kg bw respectively. However, Group V and VI received RSME (100; 200 mg/kg bw, respectively) alone. All treatments were given at alternate days for 15 days. Treatment of CCl4 to rats decreased (P < 0.001) the level of CAT, POD, SOD, GST, GSH-Px and GSR antioxidant enzymes in testes of rat. Concentration of lipid peroxides (TBARS) was increased (P < 0.001) whereas concentration of GSH was decreased (P < 0.001) in testes of CCl4 treated animals. Concentration of testosterone, FSH and LH in serum was decreased (P < 0.001) while the level of estradiol and prolactin was increased (P < 0.001) in CCl4 treated rats. Injuries in seminiferous tubules were determined in histopathology of testes. Administration of RSME, dose dependently, markedly ameliorated the oxidative stress of CCl4 thereby restoring the level of antioxidant enzymes, lipid peroxides, reduced glutathione, male hormones and alterations in histopathology.

Dietary patterns derived by statistical procedures is a way to identify overall dietary habits in specific populations. The aim of this study was to identify and characterise dietary patterns in Swedish adults using data from the national dietary survey Riksmaten adults 2010-11 (952 women, 788 men). Principal component analyses were used and two patterns were identified in both sexes: a healthy pattern loading positively on vegetables, fruits, fish and seafood, and vegetable oils, and negatively on refined bread and fast food, and a Swedish traditional pattern loading positively on potatoes, meat and processed meat, full-fat milk products, sweet bakery products, sweet condiments and margarine. In addition, a light-meal pattern was identified in women with positive loadings on fibre-rich bread, cheese, rice, pasta and food grain dishes, substitute products for meat and dairy products, candies and tea. The healthy pattern was positively correlated to dietary fibre (r 0·51-0·58) and n-3 (r 0·25-0·31) (all P<0·0001), and had a higher nutrient density of folate, vitamin D and Se. The Swedish traditional and the light-meal pattern were positively correlated to added sugar (r 0·20-0·25) and the Swedish traditional also to SFA (r 0·13-0·21) (all P<0·0001); both patterns were in general negatively correlated to micronutrients. Dietary pattern scores were associated with, for example, age, physical activity, education and income. In conclusion, we identified three major dietary patterns among Swedish adults. The patterns can be further used for examining the association between whole diet and health outcomes.

Fe fortification of centrally manufactured and frequently consumed condiments such as bouillon cubes could help prevent Fe deficiency in developing countries. However, Fe compounds that do not cause sensory changes in the fortified product, such as ferric pyrophosphate (FePP), exhibit low absorption in humans. Tetra sodium pyrophosphate (NaPP) can form soluble complexes with Fe, which could increase Fe bioavailability. Therefore, the aim of this study was to investigate Fe bioavailability from bouillon cubes fortified with either FePP only, FePP+NaPP, ferrous sulphate (FeSO4) only, or FeSO4+NaPP. We first conducted in vitro studies using a protocol of simulated digestion to assess the dialysable and ionic Fe, and the cellular ferritin response in a Caco-2 cell model. Second, Fe absorption from bouillon prepared from intrinsically labelled cubes (2·5 mg stable Fe isotopes/cube) was assessed in twenty-four Fe-deficient women, by measuring Fe incorporation into erythrocytes 2 weeks after consumption. Fe bioavailability in humans increased by 46 % (P<0·005) when comparing bouillons fortified with FePP only (4·4 %) and bouillons fortified with FePP+NaPP (6·4 %). Fe absorption from bouillons fortified with FeSO4 only and with FeSO4+NaPP was 33·8 and 27·8 %, respectively (NS). The outcome from the human study is in agreement with the dialysable Fe from the in vitro experiments. Our findings suggest that the addition of NaPP could be a promising strategy to increase Fe absorption from FePP-fortified bouillon cubes, and if confirmed by further research, for other fortified foods with complex food matrices as well.

Dietary factors in the aetiology of stomach cancer were investigated using data from a case-control study conducted in Northern Italy on 206 histologically confirmed carcinomas and 474 control subjects in hospital for acute, non-digestive conditions, unrelated to any of the potential risk factors for gastric cancer. Dietary histories concerned the frequency of consumption per week of 29 selected food items (including the major sources of starches, proteins, fats, fibres, vitamins A and C, nitrates and nitrites in the Italian diet) and subjective scores for condiments and salt intake. Pasta and rice (the major sources of starch), polenta (a porridge made of maize) and ham were positively related with gastric cancer risk, whereas green vegetables and fresh fruit as a whole (and specifically citrus fruit) and selected fibre-rich aliments (such as whole-grain bread or pasta) showed protective effects on gastric cancer risk. Allowance for major identified potential distorting factors (chiefly indicators of socio-economic status) reduced the positive association with pasta or rice consumption, but did not appreciably modify any of the other risk estimates. When a single logistic model was fitted including all food items significant in univariate analysis, the 3 items remaining statistically significant were green vegetables (relative risk, RR = 0.27 for upper vs. lower tertile), polenta (RR = 2.32) and ham (RR = 1.60). Indices of beta-carotene and ascorbate intake were negatively and strongly related with gastric cancer risk, but the association with these micronutrients was no longer evident after simultaneous allowance for various food items. An approximately 7-fold difference in risk was found between extreme quintiles of a scale measuring major positive and negative associations.

Areca nut/quid chewing is a habit that is commonly practiced in the Indian subcontinent and this age-old social habit is still being practiced by the Indians in South Africa. The areca nut/quid is prepared in a variety of ways. The quid may be prepared with or without tobacco. This habit is said to be associated with the development of oral submucous fibrosis (OSF), a premalignant lesion, oral leukoplakia and oral cancer. The aim of the present study was to investigate the prevalence of areca nut/quid chewing (with or without tobacco), associated habits (smoking and alcohol consumption) as well as the awareness of the risks. The study was cross-sectional in design and used administered questionnaires and semi-structured interviews to collect the data. A convenience sample of 101 respondents was interviewed. More than three quarter were born in South Africa and the rest were migrant communities from Pakistan, India and Dubai. All respondents from the migrant community were males. Slightly more females than maleschewed areca nut/quid. Popular ingredients that were chewed included areca nut, betel leaf, lime and paan masala. Enjoyment and special functions were the most important reasons for chewing areca nut. Family influence was a reason for chewing. Nearly 60% did not know whether areca nut chewing is harmful to their health. The majority have not attempted to give up the habit. It is recommended that aggressive awareness programmes on the hazardous effects of areca nut/quid chewing be developed similar to those for smoking cessation. Government health warnings need to be written on paan packaging. Taxes need to be imposed on the areca nut and condiments. Age restrictions need to be imposed on purchasing of the areca nut/quid thus making access difficult for the children.

Background: It has been hypothesized that monosodium glutamate (MSG), a flavor enhancer, is positively associated with weight gain, which influences energy balance through the disruption of the hypothalamic signaling cascade of leptin action. Objective: The objective was to examine the longitudinal association between MSG consumption and incidence of overweight. Design: Data were collected from the China Health and Nutrition Survey (CHNS), a prospective open-cohort, ongoing nationwide health and nutrition survey, consisting of 10,095 apparently healthy Chinese adults aged 18–65 y at entry from 1991 to 2006. Diet, including MSG and other condiments, was assessed with a weighed food inventory in combination with three 24-h recalls. Incident overweight was defined as a body mass index (BMI; in kg/m2) ≥ 25 or ≥23 based on World Health Organization recommendations for Asian populations. Multilevel mixed-effects models were constructed to estimate change in BMI, and Cox regression models with gamma shared frailty were used to determine the incidence of overweight. Results: The mean follow-up was 5.5 y. The cumulative mean (±SD) MSG intake of 2.2 ± 1.6 g/d was positively associated with BMI after adjustment for potential confounders and cluster effects at different levels (individual, household, and community). The adjusted hazard ratio of overweight was 1.33 (95% CI: 1.01, 1.75; P for trend < 0.01) for participants in the highest quintile of MSG intake compared with those in the lowest quintile after adjustment for age, physical activity, total energy intake, and other major lifestyle factors. Conclusions: MSG consumption was positively, longitudinally associated with overweight development among apparently healthy Chinese adults. Additional studies are needed to elucidate mechanisms of action and to establish causal inference. PMID:21471280

Good nutrition is a prerequisite for a healthy and active life, especially for agriculture-dependent households. However, diets in most households in Tanzania lack diversity because the intake of meat, poultry, fish, and vegetables and fruits is low. This study estimates factors influencing dietary diversity of the household, children under five years, and women using primary survey data. It qualitatively assesses male dietary patterns and men’s potential role in improving the nutritional status of the entire household. The findings show that the most consumed foods within the household are cereals, vegetables, oils and fats, spices, condiments and beverages. Children (d = 0.4; p<0.05) and women (d = 0.5; p<0.01) in female-headed households have low dietary diversity compared to those in male-headed households. Women and children access less diverse diets since 46% and 26%, achieved minimum dietary diversity respectively. Production of vegetables (coef. 0.34; p<0.05) play an important role in improving the dietary diversity of women. Gender (coef. 0.05; p<0.10) and education of the household head (coef. 0.02; p<0.01), food preparation and nutrition training (coef. 0.10; p<0.05) are important factors influencing dietary diversity of the members of a household. Results suggest that there is a need to support community-based programs to provide information on food and the importance of vegetables, their preparation, consumption and utilization to address food and nutrition challenges. Men can contribute towards improving household nutrition security by reducing consumption of food away from the home, especially during periods of food shortages. We recommend the use of complementary quantitative research to determine the patterns and dynamics of men’s dietary diversity and compare it with that of other household members. PMID:29232413

Background This study characterized the botanical knowledge of artisanal fishers of the Lami community, Porto Alegre, southern Brazil based on answers to the following question: Is the local botanical knowledge of the artisanal fishers of the rural-urban district of Lami still active, even since the district’s insertion into the metropolitan region of Porto Alegre? Methods This region, which contains a mosaic of urban and rural areas, hosts the Lami Biological Reserve (LBR) and a community of 13 artisanal fisher families. Semi-structured interviews were conducted with 15 fishers, complemented by participatory observation techniques and free-lists; in these interviews, the species of plants used by the community and their indicated uses were identified. Results A total of 111 species belonging to 50 families were identified. No significant differences between the diversities of native and exotic species were found. Seven use categories were reported: medicinal (49%), human food (23.2%), fishing (12.3%), condiments (8%), firewood (5%), mystical purposes (1.45%), and animal food (0.72%). The medicinal species with the highest level of agreement regarding their main uses (AMUs) were Aloe arborescens Mill., Plectranthus barbatus Andrews, Dodonaea viscosa Jacq., Plectranthus ornatus Codd, Eugenia uniflora L., and Foeniculum vulgare Mill. For illness and diseases, most plants were used for problems with the digestive system (20 species), followed by the respiratory system (16 species). This community possesses a wide botanical knowledge, especially of medicinal plants, comparable to observations made in other studies with fishing communities in coastal areas of the Atlantic Forest of Brazil. Conclusions Ethnobotanical studies in rural-urban areas contribute to preserving local knowledge and provide information that aids in conserving the remaining ecosystems in the region. PMID:23898973

The ability of various species of Bacillus from fermented seeds of Parkia biglobosa known as African locust bean (Soumbala) and fermented seeds of Hibiscus sabdariffa (Bikalga) was investigated. The study included screening of the isolates by haemolysis on blood agar, detection of toxins in broth and during the fermentation of African locust bean using the Bacillus cereus Enterotoxin Reverse Passive Latex Agglutination test kit (BCET-RPLA) and the Bacillus Diarrhoeal Enterotoxin Visual Immunoassay (BDEVIA). Detection of genes encoding cytotoxin K (CytK), haemolysin BL (Hbl A, Hbl C, Hbl D), non-hemolytic enterotoxin (NheA, NheB, NheC) and EM1 specific of emetic toxin producers was also investigated using PCR with single pair and multiplex primers. Of 41 isolates, 29 Bacillus belonging to the species of B. cereus, Bacillus subtilis, Bacillus licheniformis and Bacillus pumilus showed haemolysis on blood agar. Using RPLA, enterotoxin production was detected for three isolates of B. cereus in broth and all B. cereus (9) in fermented seeds. Using BDEVIA, enterotoxin production was detected in broth as well as in fermented seeds for all B. cereus isolates. None of the isolates belonging to the other Bacillus species was able to produce enterotoxins either by RPLA or BDEVIA. Nhe genes were detected in all B. cereus while Hbl and CytK genes were detected respectively in five and six B. cereus strains. A weak presence of Hbl (A, D) and CytK genes was detected in two isolates of B. subtilis and one of B. licheniformis but results were inconsistent, especially for Hbl genes. The emetic specific gene fragment EM1 was not detected in any of the isolates studied.

Among young Samoan children, diet may not be optimal: in 2015, 16·1 % of 24-59-month-olds were overweight/obese, 20·3 % stunted and 34·1 % anaemic. The present study aimed to identify dietary patterns among 24-59-month-old Samoan children and evaluate their association with: (i) child, maternal and household characteristics; and (ii) nutritional status indicators (stunting, overweight/obesity, anaemia). A community-based, cross-sectional study. Principal component analysis on 117 FFQ items was used to identify empirical dietary patterns. Distributions of child, maternal and household characteristics were examined by factor score quintiles. The regression of nutritional status indicators v. these quintiles was performed using logistic regression models. Ten villages on the Samoan island of Upolu. A convenience sample of mother-child pairs (n 305). Two dietary patterns, modern and neo-traditional, emerged. The modern pattern was loaded with 'westernized' foods (red meat, condiments and snacks). The neo-traditional pattern included vegetables, local starches, coconuts, fish and poultry. Following the modern diet was associated with urban residence, greater maternal educational attainment, higher socio-economic status, lower vitamin C intake and higher sugar intake. Following the neo-traditional diet was associated with rural residence, lower socio-economic status, higher vitamin C intake and lower sugar intake. While dietary patterns were not related to stunting or anaemia, following the neo-traditional pattern was positively associated with child overweight/obesity (adjusted OR=4·23, 95 % CI 1·26, 14·17, for the highest quintile, P-trend=0·06). Further longitudinal monitoring and evaluation of early childhood growth and development are needed to understand the influences of early diet on child health in Samoa.

Irritable bowel syndrome (IBS) in the outpatient with chronic inflammatory bowel disease (IBD) is a difficult but important challenge to recognize and treat. It is very helpful to have effective treatment approaches for IBS that are practical and use minimal medications. Because of the underlying chronic inflammation in IBD, IBS symptoms occur with increased frequency and severity, secondary to increased hypersensitivity to foods and beverages that stimulate the gastrointestinal tract. This paper discusses how to treat IBS in the IBD outpatient, with emphasis on using a food and beverage intolerance, avoidance diet. The adverse effects of many foods and beverages are amount dependent and can be delayed, additive, and cumulative. The specific types of foods and beverages that can induce IBS symptoms include milk and milk containing products; caffeine containing products; alcoholic beverages; fruits; fruit juices; spices; seasonings; diet beverages; diet foods; diet candies; diet gum; fast foods; condiments; fried foods; fatty foods; multigrain breads; sourdough breads; bagels; salads; salad dressings; vegetables; beans; red meats; gravies; spaghetti sauce; stews; nuts; popcorn; high fiber; and cookies, crackers, pretzels, cakes, and pies. The types of foods and beverages that are better tolerated include water; rice; plain pasta or noodles; baked or broiled potatoes; white breads; plain fish, chicken, turkey, or ham; eggs; dry cereals; soy or rice based products; peas; applesauce; cantaloupe; watermelon; fruit cocktail; margarine; jams; jellies; and peanut butter. Handouts that were developed based upon what worsens or helps IBS symptoms in patients are included to help patients learn which foods and beverages to avoid and which are better tolerated.

Within the past decade, there has been increasing attention to the role of fast food in the American diet, including a rise in legislative and media-based efforts that address the healthfulness of fast food. However, no studies have been undertaken to evaluate changes in the energy content of fast-food chain restaurant menu items during this period. To examine changes in the energy content of lunch/dinner menu offerings at eight of the leading fast-food chain restaurants in the U.S. between 1997-1998 and 2009-2010. Menu offerings and nutrient composition information were obtained from archival versions of the University of Minnesota Nutrition Coordinating Center Food and Nutrient Database. Nutrient composition information for items was updated biannually. Changes in median energy content of all lunch/dinner menu offerings and specific categories of menu items among all restaurants and for individual restaurants were examined. Data were collected between 1997 and 2010 and analysis was conducted in 2011. Spanning 1997-1998 and 2009-2010, the number of lunch/dinner menu items offered by the restaurants in the study increased by 53%. Across all menu items, the median energy content remained relatively stable over the study period. Examining specific food categories, the median energy content of desserts and condiments increased, the energy content of side items decreased, and energy content of entrées and drinks remained level. Although large increases in the number of menu items were observed, there have been few changes in the energy content of menu offerings at the leading fast-food chain restaurants examined in this study.

Dietary habits established in early childhood and maternal socioeconomic status (SES) are important, complex, interrelated factors that influence a child's growth and development. The aim of this study was to define the major dietary patterns in a cohort of young US children, construct a maternal SES index, and evaluate their associations. The diets of 190 children from a randomized, controlled trial of prenatal supplementation of docosahexaenoic acid (DHA) were recorded at 6-mo intervals from 2-4.5 years by 24-h dietary recall. Hierarchical cluster analysis of age-adjusted, average daily intake of 24 food and beverage groups was used to categorize diet. Unrotated factor analysis generated an SES score from maternal race, ethnicity, age, education, and neighborhood income. We identified two major dietary patterns: "Prudent" and "Western." The 85 (45%) children with a Prudent diet consumed more whole grains, fruit, yogurt and low-fat milk, green and non-starchy vegetables, and nuts and seeds. Conversely, those with a Western diet had greater intake of red meat, discretionary fat and condiments, sweet beverages, refined grains, French fries and potato chips, eggs, starchy vegetables, processed meats, chicken and seafood, and whole-fat milk. Compared to a Western diet, a Prudent diet was associated with one standard deviation higher maternal SES (95% CI: 0.80 to 1.30). We found two major dietary patterns of young US children and defined a single, continuous axis of maternal SES that differed strongly between groups. This is an important first step to investigate how child diet, SES, and prenatal DHA supplementation interact to influence health outcomes. NCT00266825 .

The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger, is one of the most widely used spice and condiment. It is also an integral part of many traditional medicines and has been extensively used in Chinese, Ayurvedic, Tibb-Unani, Srilankan, Arabic, and African traditional medicines, since antiquity, for many unrelated human ailments including common colds, fever, sore throats, vomiting, motion sickness, gastrointestinal complications, indigestion, constipation, arthritis, rheumatism, sprains, muscular aches, pains, cramps, hypertension, dementia, fever, infectious diseases, and helminthiasis. The putative active compounds are nonvolatile pungent principles, namely gingerols, shogaols, paradols, and zingerone. These compounds are some of the extensively studied phytochemicals and account for the antioxidant, anti-inflammatory, antiemetic, and gastroprotective activities. A number of preclinical investigations with a wide variety of assay systems and carcinogens have shown that ginger and its compounds possess chemopreventive and antineoplastic effects. A number of mechanisms have been observed to be involved in the chemopreventive effects of ginger. The cancer preventive activities of ginger are supposed to be mainly due to free radical scavenging, antioxidant pathways, alteration of gene expressions, and induction of apoptosis, all of which contribute towards decrease in tumor initiation, promotion, and progression. This review provides concise information from preclinical studies with both cell culture models and relevant animal studies by focusing on the mechanisms responsible for the chemopreventive action. The conclusion describes directions for future research to establish its activity and utility as a human cancer preventive and therapeutic drug. The above-mentioned mechanisms of ginger seem to be promising for cancer prevention; however, further clinical studies are warranted to assess the efficacy and safety of ginger.

Onion is used widely as a condiment for meat and other types of food in Iran. Because of the high sensitivity of this product to storage conditions and having not enough storage under controlled atmosphere (CA), the effects of drying method, packaging, and temperature during storage on thin slices of fried red Azershahr variety onion were investigated. To prepare this processed food with excellent organoleptic properties and useful in the food service industry onions were sliced (2 mm), deep-fried with corn frying oil in a batch fryer at 150 degrees C, and dried to a water content of 3-4% in a hot-air dryer at 70 degrees C for 24 h and a microwave system. Samples were packed in aluminum foil, which was purged by nitrogen gas, and cellophane-sealed with thermal sewing. Then these samples were kept for one year at laboratory temperature and in a freezer at -18 degrees C. During the storage time the moisture content, peroxide value, vitamin C content, total microbial count (TMC), and organoleptic characteristics of the samples were analyzed every 2 mo. The results of microbial analyses indicated that after 6 mo all of the samples had higher TMCs than the permission limits so the expiration date was set before that. The moisture contents and peroxide values showed a noticeable increase, probably due to seal failure, whereas vitamin C decreased up to 66% during storage. The loss of sensory properties was parallel to the microbial and chemical results. The findings revealed that the best sample was oven-dried, packed in aluminum foil under inert gas, and kept in a freezer (OAF) up to 6 mo.

A reduced incidence of different types of cancer has been linked to consumption of Brassica vegetables, and there is evidence that glucosinolates (GSLs) and their hydrolysis products play a role in reducing cancer risk. Wasabi (Wasabia japonica) and horseradish (Armoracia rusticana), both Brassica vegetables, are widely used condiments both in Japanese cuisine and in the United States. Desulfosinigrin (DSS) (1) was isolated from a commercially available wasabi powder and from fresh wasabi roots. Sinigrin (2) was isolated from horseradish roots. DSS and sinigrin were evaluated for their inhibitory effects on cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, on lipid peroxidation, and on the proliferation of human colon (HCT-116), breast (MCF-7), lung (NCIH460), and central nervous system (CNS, SF-268) cancer cell lines. DSS did not inhibit COX enzymes or lipid peroxidation at 250 microg/ml. Sinigrin inhibited lipid peroxidation by 71% at 250 microg/ml. However, DSS promoted the growth of HCT-116 (colon) and NCI H460 (lung) human cancer cells as determined by the MTT assay in a concentration-dependent manner. At 3.72 microg/ml, a 27% increase in the number of viable human HCT-116 colon cancer cells was observed; the corresponding increases at 7.50 and 15 microg/ml were 42 and 69%, respectively. At 60 microg/ml, DSS doubled the number of HCT-16 colon cancer cells. For NCI H460 human lung cancer cells, DSS at 60 microg/ml increased the cell number by 20%. Sinigrin showed no proliferating effect on the tumor cells tested. This is the first report of the tumor cell-proliferating activity by a desulfoglucosinolate, the biosynthetic precursor of GSLs found in Brassica spp.

Rhizoma Alpinia officinarum (Hance) Farw, Zingiberaceae (AO), a ginger family herb exhibiting stimulant and a carminative bioactivity, is widely used in European and Asian countries as spicy condiment and medicinal uses. Allyl isothiocyanate (AITC) is the main pungent taste of native Wasabi (Wasabia japonica). The cytotoxicity of AITC has been implicated in thymus, adrenals, and white blood cells. Considering food safety, apparently a safer substitute for wasabi is worthy commercialized. Previously, we found AO crude paste to be rather feasible for use as a "Wasabi-substitute" in fresh meat and cold salads. A process linking cold ethyl acetate (EtAc) extraction with silica gel adsorption and reversed phase high-performance liquid chromatography (RP-HPLC) (mobile phase, 75% methanol) was used to isolate galangal acetate, the Wasabi-like taste constituent. AO contained abundant galangal acetate (3.84 ± 0.07%) compared to A. galangal (0.57 ± 0.16%), and as already confirmed by thin layer chromatography (TLC), gas chromatography (GC)/mass spectrometry (MS)/MS and Nuclear Magnetic Resonance Spectroscopy (NMR), galangal acetate was particularly thermally labile. The steam distilled essential oil (SDEO) of AO (0.14% on wet basis) contained 80 compounds (number of component, %): monoterpene hydrocarbon (21, 13.83%); oxygenated monoterpene (17, 27.08%); sesquiterpene hydrocarbon (20, 31.03%), and oxygenated sesquiterpene (20, 21.85%), respectively. However, no spicy wasabi-like constituent remained in SDEO. Alternatively, n-hexane, EtAc, and methanol extracts of AO all showed potent DPPH- and superoxide anion-scavenging activity. Conclusively, SDEO although contains 80 volatiles, galangal acetate is absent due to thermal instability. Galangal acetate exhibits pleasant "Wasabi-like taste" for which we have successively developed an integrated process for mass production. © 2016 Institute of Food Technologists®

Using Fish Sauce as a Substitute for Sodium Chloride in Culinary Sauces and Effects on Sensory Properties.

PubMed

Historically, fish sauce has been a standard condiment and ingredient in various Southeast Asian cuisines. Moreover, fish sauce imparts umami taste, which may enhance perceived saltiness in food. This quality suggests that fish sauce may be used as a partial substitute for sodium chloride (NaCl) in food preparation, which may present a valuable option for health-conscious and salt-restricted consumers. However, the degree to which NaCl can be decreased in food products without compromising taste and consumer acceptance has not been determined. We hypothesized that NaCl content in food may be reduced by partial replacement with fish sauce without diminishing palatability and consumer acceptance. Preparations of 3 types of food were assessed to test this hypothesis: chicken broth (n = 72); tomato sauce (n = 73); and coconut curry (n = 70). In the first session, the percentage of NaCl that could be replaced with fish sauce without a significant change in overall taste intensity was determined for each type of food using the 2-Alternative Forced Choice method. In the second session, subjects rated 5 samples for each food with varying NaCl and/or fish sauce content on 3 sensory attributes: deliciousness; taste intensity; and saltiness. Our results demonstrate that NaCl reduction was possible in chicken broth, tomato sauce, and coconut curry at 25%, 16%, and 10%, respectively, without a significant loss (P < 0.05) in deliciousness and overall taste intensity. These results suggest that it is possible to replace NaCl in foods with fish sauce without reducing overall taste intensity and consumer acceptance. © 2015 Institute of Food Technologists®

The aim of this study was to determine the intake and food sources of potassium and the molar sodium:potassium (Na:K) ratio in a sample of Australian pre-school children. Mothers provided dietary recalls of their 3.5 years old children (previous participants of Melbourne Infant Feeding Activity and Nutrition Trial). The average daily potassium intake, the contribution of food groups to daily potassium intake, the Na:K ratio, and daily serves of fruit, dairy, and vegetables, were assessed via three unscheduled 24 h dietary recalls. The sample included 251 Australian children (125 male), mean age 3.5 (0.19) (SD) years. Mean potassium intake was 1618 (267) mg/day, the Na:K ratio was 1.47 (0.5) and 54% of children did not meet the Australian recommended adequate intake (AI) of 2000 mg/day for potassium. Main food sources of potassium were milk (27%), fruit (19%), and vegetable (14%) products/dishes. Food groups with the highest Na:K ratio were processed meats (7.8), white bread/rolls (6.0), and savoury sauces and condiments (5.4). Children had a mean intake of 1.4 (0.75) serves of fruit, 1.4 (0.72) dairy, and 0.52 (0.32) serves of vegetables per day. The majority of children had potassium intakes below the recommended AI. The Na:K ratio exceeded the recommended level of 1 and the average intake of vegetables was 2 serves/day below the recommended 2.5 serves/day and only 20% of recommended intake. An increase in vegetable consumption in pre-school children is recommended to increase dietary potassium and has the potential to decrease the Na:K ratio which is likely to have long-term health benefits.

Obesity is a growing problem in India, the dietary determinants of which have been studied using an 'individual food/nutrient' approach. Examining dietary patterns may provide more coherent findings, but few studies in developing countries have adopted this approach. The present study aimed to identify dietary patterns in an Indian population and assess their relationship with anthropometric risk factors. FFQ data from the cross-sectional sib-pair Indian Migration Study (IMS; n 7067) were used to identify dietary patterns using principal component analysis. Mixed-effects logistic regression was used to examine associations with obesity and central obesity. The IMS was conducted at four factory locations across India: Lucknow, Nagpur, Hyderabad and Bangalore. The participants were rural-to-urban migrant and urban non-migrant factory workers, their rural and urban resident siblings, and their co-resident spouses. Three dietary patterns were identified: 'cereals-savoury foods' (cooked grains, rice/rice-based dishes, snacks, condiments, soups, nuts), 'fruit-veg-sweets-snacks' (Western cereals, vegetables, fruit, fruit juices, cooked milk products, snacks, sugars, sweets) and 'animal-food' (red meat, poultry, fish/seafood, eggs). In adjusted analysis, positive graded associations were found between the 'animal-food' pattern and both anthropometric risk factors. Moderate intake of the 'cereals-savoury foods' pattern was associated with reduced odds of obesity and central obesity. Distinct dietary patterns were identified in a large Indian sample, which were different from those identified in previous literature. A clear 'plant food-based/animal food-based pattern' dichotomy emerged, with the latter being associated with higher odds of anthropometric risk factors. Longitudinal studies are needed to further clarify this relationship in India.

Spices and herbs are recognized sources of natural antioxidants that can protect from oxidative stress, thus play an important role in chemoprevention of liver diseases. Ginger is used worldwide primarily as a spicy condiment. This study evaluated the ability of ginger extract (GE) to ameliorate oxidative-hepatic toxicity induced by lead acetate (PbAc) in rats. Five groups of animals were used: group I kept as control; groups II, IV, and V received PbAc (1 ppm in drinking water daily for 6 weeks, and kept for an additional 2 weeks without PbAc exposure); group III treated orally with GE (350 mg/kg body weight, 4 d per week) for 6 weeks; group IV (protective) received GE for 2 weeks before and simultaneously with PbAc; and group V (treatment) received GE for 2 weeks after PbAc exposure. GC-MS analysis of GE revealed its content of gingerol (7.09%), quercetin (3.20%), dl-limonene (0.96%), and zingiberene (0.18%). Treatment of PbAc-treated rats with GE has no effect on hepatic Pb concentrations. However, it maintained serum aspartate aminotransferase level, increased hepatic glutathione (157%), glutathione S-transferase (GST) (228%), glutathione peroxidase (GPx) (138%) and catalase (CAT) (112%) levels, and reduced hepatic malondialdehyde (80%). Co-treatment of PbAc group with GE upregulated mRNA expression of antioxidant genes: GST-α1 (1.4-fold), GPx1 (1.8-fold), and CAT (8-fold), while post-treatment with GE upregulated only mRNA expression of GPx1 (1.5-fold). GE has an antioxidant protective efficacy against PbAc-induced hepatotoxicity, which appears more effective than its therapeutic application. However, the changes in antioxidant gene expression were not reflected at the protein level.

The aim of this study was to determine the intake and food sources of potassium and the molar sodium:potassium (Na:K) ratio in a sample of Australian pre-school children. Mothers provided dietary recalls of their 3.5 years old children (previous participants of Melbourne Infant Feeding Activity and Nutrition Trial). The average daily potassium intake, the contribution of food groups to daily potassium intake, the Na:K ratio, and daily serves of fruit, dairy, and vegetables, were assessed via three unscheduled 24 h dietary recalls. The sample included 251 Australian children (125 male), mean age 3.5 (0.19) (SD) years. Mean potassium intake was 1618 (267) mg/day, the Na:K ratio was 1.47 (0.5) and 54% of children did not meet the Australian recommended adequate intake (AI) of 2000 mg/day for potassium. Main food sources of potassium were milk (27%), fruit (19%), and vegetable (14%) products/dishes. Food groups with the highest Na:K ratio were processed meats (7.8), white bread/rolls (6.0), and savoury sauces and condiments (5.4). Children had a mean intake of 1.4 (0.75) serves of fruit, 1.4 (0.72) dairy, and 0.52 (0.32) serves of vegetables per day. The majority of children had potassium intakes below the recommended AI.

Background Among the naturally occurring compounds, turmeric from the dried rhizome of the plant Curcuma longa has long been used extensively as a condiment and a household remedy all over Southeast Asia. Turmeric contains essential oil, yellow pigments (curcuminoids), starch and oleoresin. The present study was designed for investigating the neuroprotective efficacy and the time window for effective therapeutic use of Curcuma oil (C. oil). Method In the present study, the effect of post ischemic treatment of C.oil after ischemia induced by occlusion of the middle cerebral artery in the rat was observed. C.oil (500 mg/kg body wt) was given 4 hrs post ischemia. The significant effect on lesion size as visualized by using diffusion-weighted magnetic resonance imaging and neuroscore was still evident when treatment was started 4 hours after insult. Animals were assessed for behavioral deficit scores after 5 and 24 hours of ischemia. Subsequently, the rats were sacrificed for evaluation of infarct and edema volumes and other parameters. Results C.oil ameliorated the ischemia induced neurological functional deficits and the infarct and edema volumes measured after 5 and 24 hrs of ischemia. After 24 hrs, immunohistochemical and Western blot analysis demonstrated that the expression of iNOS, cytochrome c and Bax/Bcl-2 were altered after the insult, and antagonized by treatment with C.oil. C.oil significantly reduced nitrosative stress, tended to correct the decreased mitochondrial membrane potential, and also affected caspase-3 activation finally apoptosis. Conclusion Here we demonstrated that iNOS-derived NO produced during ischemic injury was crucial for the up-regulation of ischemic injury targets. C.oil down-regulates these targets this coincided with an increased survival rate of neurons. PMID:18826584

In this study, mixed hemimicelles solid-phase extraction (MHSPE) based on sodium dodecyl sulfate (SDS) coated nano-magnets Fe3O4 was investigated as a novel method for the extraction and separation of four banned cationic dyes, Auramine O, Rhodamine B, Basic orange 21 and Basic orange 22, in condiments prior to HPLC detection. The main factors affecting the extraction of analysts, such as pH, surfactant and adsorbent concentrations and zeta potential were studied and optimized. Under optimized conditions, the proposed method was successful applied for the analysis of banned cationic dyes in food samples such as chili sauce, soybean paste and tomato sauce. Validation data showed the good recoveries in the range of 70.1-104.5%, with relative standard deviations less than 15%. The method limits of determination/quantification were in the range of 0.2-0.9 and 0.7-3μgkg(-1), respectively. The selective adsorption and enrichment of cationic dyes were achieved by the synergistic effects of hydrophobic interactions and electrostatic attraction between mixed hemimicelles and the cationic dyes, which also resulted in the removal of natural pigments interferences from sample extracts. When applied to real samples, RB was detected in several positive samples (chili powders) within the range from 0.042 to 0.177mgkg(-1). These results indicate that magnetic MHSPE is an efficient and selective sample preparation technique for the extraction of banned cationic dyes in a complex matrix. Copyright © 2016 Elsevier B.V.

Evidence that diet is associated with breast cancer risk is inconsistent. Most studies have examined risks associated with specific foods and nutrients, rather than measures of overall diet. This study aimed to evaluate dietary patterns and their relation to breast cancer risk in a large cohort of women. Data from 91,779 women in the California Teachers Study cohort were analyzed, including data from 4140 women with a diagnosis of invasive breast cancer made between 1995 and 2009. Five predominant dietary patterns were identified by using principal components factor analysis: a plant-based diet, high in fruit and vegetables; a high-protein, high-fat diet, high in meats, eggs, fried foods, and high-fat condiments; a high-carbohydrate diet, high in convenience foods, pasta, and bread products; an ethnic diet, high in legumes, soy-based foods, rice, and dark-green leafy vegetables; and a salad and wine diet, high in lettuce, fish, wine, low-fat salad dressing, and coffee and tea. The plant-based pattern was associated with a reduction in breast cancer risk (RR: 0.85; 95% CI: 0.76, 0.95 for the highest compared with the lowest consumption quintile; P-trend = 0.003); risk reduction was greater for estrogen receptor-negative progesterone receptor-negative (ER-PR-) tumors (RR: 0.66; 95% CI: 0.48, 0.91; P-trend = 0.03). The salad and wine pattern was associated with an increased risk of estrogen receptor-positive progesterone receptor-positive tumors (RR: 1.29; 95% CI: 1.12, 1.49); this effect was only slightly attenuated after adjustment for alcohol consumption. The finding that greater consumption of a plant-based dietary pattern is associated with a reduced breast cancer risk, particularly for ER-PR- tumors, offers a potential avenue for prevention.

Alert for an epidemic of oral cancer due to use of the betel quid substitutes gutkha and pan masala: a review of agents and causative mechanisms.

In south-east Asia, Taiwan and Papua New Guinea, smoking, alcohol consumption and chewing of betel quid with or without tobacco or areca nut with or without tobacco are the predominant causes of oral cancer. In most areas, betel quid consists of a mixture of areca nut, slaked lime, catechu and several condiments according to taste, wrapped in a betel leaf. Almost all habitual chewers use tobacco with or without the betel quid. In the last few decades, small, attractive and inexpensive sachets of betel quid substitutes have become widely available. Aggressively advertised and marketed, often claimed to be safer products, they are consumed by the very young and old alike, particularly in India, but also among migrant populations from these areas world wide. The product is basically a flavoured and sweetened dry mixture of areca nut, catechu and slaked lime with tobacco (gutkha) or without tobacco (pan masala). These products have been strongly implicated in the recent increase in the incidence of oral submucous fibrosis, especially in the very young, even after a short period of use. This precancerous lesion, which has a high rate of malignant transformation, is extremely debilitating and has no known cure. The use of tobacco with lime, betel quid with tobacco, betel quid without tobacco and areca nut have been classified as carcinogenic to humans. As gutkha and pan masala are mixtures of several of these ingredients, their carcinogenic affect can be surmised. We review evidence that strongly supports causative mechanisms for genotoxicity and carcinogenicity of these substitute products. Although some recent curbs have been put on the manufacture and sale of these products, urgent action is needed to permanently ban gutkha and pan masala, together with the other established oral cancer-causing tobacco products. Further, education to reduce or eliminate home-made preparations needs to be accelerated.

Regulatory Monitoring of Fortified Foods: Identifying Barriers and Good Practices

Rowe, Laura A; Vossenaar, Marieke; Garrett, Greg S

2015-01-01

While fortification of staple foods and condiments has gained enormous global traction, poor performance persists throughout many aspects of implementation, most notably around the critical element of regulatory monitoring, which is essential for ensuring foods meet national fortification standards. Where coverage of fortified foods is high, limited nutritional impact of fortification programs largely exists due to regulatory monitoring that insufficiently identifies and holds producers accountable for underfortified products. Based on quality assurance data from 20 national fortification programs in 12 countries, we estimate that less than half of the samples are adequately fortified against relevant national standards. In this paper, we outline key findings from a literature review, key informant interviews with 11 fortification experts, and semi-quantitative surveys with 39 individuals from regulatory agencies and the food fortification industry in 17 countries on the perceived effectiveness of regulatory monitoring systems and barriers to compliance against national fortification standards. Findings highlight that regulatory agencies and industry disagree on the value that enforcement mechanisms have in ensuring compliance against standards. Perceived political risk of enforcement and poorly resourced inspectorate capacity appear to adversely reinforce each other within an environment of unclear legislation to create a major hurdle for improving overall compliance of fortification programs against national standards. Budget constraints affect the ability of regulatory agencies to create a well-trained inspector cadre and improve the detection and enforcement of non-compliant and underfortified products. Recommendations to improve fortification compliance include improving technical capacity; ensuring sustained leadership, accountability, and funding in both the private and the public sectors; and removing political barriers to ensure consistent detection of underfortified products and enforcement of applicable fortification standards. Only by taking concrete steps to improve the entire regulatory system that is built on a cooperative working relationship between regulatory agencies and food producers will a nutrition strategy that uses fortification see its intended health effects.

Soybeans which had initially been dehulled by either boiling (boiled/dehulled) or roasting (roasted/dehulled) before peeling, were cooked and fermented into dawadawa, a traditional food condiment. The micropopulation, enzymatic activities, proximate composition, amino acid, and aroma profiles of the two types of soybean dawadawa were evaluated during fermentation. Only minor differences were found in the microbial profiles of the two types of soy-dawadawa. Although boiled/dehulled soy-dawadawa initially had lower microbial counts, it recorded higher counts at the advanced stages of fermentation. Proteolytic and amylolytic Bacillus species including Bacillus subtilis, Bacillus pumilus, Bacillus licheniformis, Bacillus cereus, and Bacillus firmus dominated the micropopulation of the two types of soy-dawadawa with Bacillus subtilis accounting for about 50% of the Bacillus species in all samples. Lactic acid bacteria and yeasts occurred in low numbers in the two types of soy-dawadawa. The proximate composition of the two types of soy-dawadawa were similar, and their contents of moisture and protein increased whilst fat and ash decreased during fermentation. Both types of fermenting soy-dawadawa recorded similar levels of alpha-amylase activity, but boiled/dehulled soy-dawadawa showed slightly higher protease activity. The levels of isoleucine, leucine, lysine, phenylalanine, arginine and proline increased significantly with fermentation time in both types of soy-dawadawa. With respect to differences in their aroma profiles, hexanodecanol, octadecyl acetate, 1,2-dimethyl benzene, tetradecene, (E)-5-eicosene, cyclohexadecane, and hexacosane were found only in the roasted/dehulled samples, whilst 1,2-ethanediol, ethyl acetate, dimethyl disulfide, cyclotetradecane, decene, indole , 2 butyl-octenal, acetophenone, and toluene were found only in the boiled/dehulled samples. A market focus group showed preference for roasted/dehulled soy-dawadawa over boiled/dehulled soy-dawadawa. Apart from the volatile aroma compounds, the biochemical and microbiological profiles of the two types of soy-dawadawa showed only minor differences and were also similar to the profiles reported for African locust bean dawadawa.

The most popular form of utilization of African locust bean (ALB) is in its traditional fermentation food condiment (iru/dawadawa), which adds protein to a protein-poor diet and also as medicine. In view of the nutritive values of ALB, the present study therefore aimed at investigating the effect of germination and fermentation on the nutritional quality of ALB flour. The ALB was obtained from a local market in Akure, Nigeria. The seeds were divided into three portions, and treated as raw African locust bean (RALB), germinated African locust bean (GALB) and fermented African locust bean (FALB) respectively. Each of the samples was milled, sieved and analysed for chemical, functional properties and nutritional qualities using standard methods. Some most important results of the chemical analysis were as follows: protein content range between 33.64 ±0.41 - 41.49 ±1.89 g/100 g, while the energy value was between 442.79 ±2.32 - 457.20 ±2.15 kcal. The P/Ca and Na/K ratio of the RALB were higher than other fl our samples respectively. Total essential amino acid was between 29.960-27.514 mg/100 g. Protein efficiency ratio (PER) was between 1.78-1.87; essential amino acid index 31.43-34.75%; while biological values were 22.56-26.18%. The dominant fatty acid (FA) composition of the samples was linoleic with 33.687%, 31.578% and 28.7% for RALB, GALB and FALB respectively; while the least was lauric acid. The polyunsaturated/saturated FA ratio ranges between 0.589-0.718. The antinutrient concentration of fermented flour sample was significantly reduced than other food samples. The present study investigated the effect of germination and fermentation on the nutritional quality of ALB flour. The finding showed that fermentation technique significantly reduced antinutrient concentration and also improved the nutrient composition, particularly amino acid profile of ALB flour.

Garlic is cultivated and consumed worldwide as a popular condiment and green vegetable with medicinal and neutraceutical properties. Garlic cultivars do not produce seeds, and therefore, this plant has not been the subject of either classical breeding or genetic studies. However, recent achievements in fertility restoration in a number of genotypes have led to flowering and seed production, thus enabling genetic studies and breeding in garlic. A transcriptome catalogue of fertile garlic was produced from multiplexed gene libraries, using RNA collected from various plant organs, including inflorescences and flowers. Over 32 million 250-bp paired-end reads were assembled into an extensive transcriptome of 240,000 contigs. An abundant transcriptome assembled separately from 102,000 highly expressed contigs was annotated and analyzed for gene ontology and metabolic pathways. Organ-specific analysis showed significant variation of gene expression between plant organs, with the highest number of specific reads in inflorescences and flowers. Analysis of the enriched biological processes and molecular functions revealed characteristic patterns for stress response, flower development and photosynthetic activity. Orthologues of key flowering genes were differentially expressed, not only in reproductive tissues, but also in leaves and bulbs, suggesting their role in flower-signal transduction and the bulbing process. More than 100 variants and isoforms of enzymes involved in organosulfur metabolism were differentially expressed and had organ-specific patterns. In addition to plant genes, viral RNA of at least four garlic viruses was detected, mostly in the roots and cloves, whereas only 1-4% of the reads were found in the foliage leaves. The de novo transcriptome of fertile garlic represents a new resource for research and breeding of this important crop, as well as for the development of effective molecular markers for useful traits, including fertility and seed production, resistance to pests and neutraceutical characteristics.

To study the rates of infection and physicochemical characteristics of the third stage Anisakis simplex larvae among marine fish caught in Zhoushan Fishery. Fish were dissected to detect Anisakis larvae and identified morphologically. The survival tolerance of the third stage Anisakis simplex larvae in various medium, anthelmintic drug, temperature were studied in laboratory. The total infection rate of Anisakis simplex larvae in fish was 49.10%. High rates of Anisakis infection were observed in hairtails, Pneumatophorus japonicus, Miichthys milky, Argyrosomus argentatus and Muraenesox cinereus (infection rates > 90 percent). The infection intensity of Anisakis per fish varied from 1 to 114. The mean intensity of Anisakis larvae was 15.20 per fish. 3314 Anisakis were detected in 218 marine fish. The survival tolerance of the third stage Anisakis simplex larvae in various Medium, anthelmintic drug, temperature were observed in laboratory condition. The third stage Anisakis simplex larvae showed a strong endurance to stock condiment. The anisakicidal effects of the high purity wine were more effective than that of the low purity wine. The anisakicidal effects of 6.25 g/L mebendazole composite were more effective than that of 18.75 g/L and also more effective than those of other drugs. The third stage Anisakis simplex larvae could survive with length up to 9 h and 12 h in condition of -20°C, -10°C and very sensitive to high temperature treatment. However, they could barely survive in more than 11 s and 1 s under the temperature of 50°C and 60°C. The percentage of infection was fairly high for Anisakis larvae of marine fish caught in Zhoushan Fishery. The third stage Anisakis simplex larvae was shown to have a fairly good tolerance to the external environments. The marine fish were frozen under -20°C beyond 24 h before they were sold on market and cooked with high temperature seemed to be helpful for preventing and controlling effectively the infection of Anisakis.

Major multinational food and beverage companies and informal sector contributions to global food consumption: implications for nutrition policy.

In recent years, 10 major multinational food and beverage companies have worked together within the International Food and Beverage Alliance (IFBA) to increase their commitments to public health. Current IFBA commitments include initiatives to improve the nutrition quality of products and how these products are advertised to children. The impact and magnitude of IFBA member contributions to the total market share of packaged foods and beverages consumed remain incompletely understood, however. In order to evaluate this impact, we examined packaged food and soft drink company shares provided by Euromonitor, an international independent market analysis company. Packaged foods include baby food, bakery, canned/preserved food, chilled/processed food, confectionery, dairy, dried processed food, frozen processed food, ice cream, meal replacement, noodles, oils and fats, pasta, ready meals, sauces, dressings and condiments, snack bars, soup, spreads, and sweet and savoury snacks. Soft drinks include carbonates, packaged fruit/vegetable juice, bottled water, functional drinks, concentrates, ready-to-drink tea, ready-to-drink coffee and Asian specialty drinks. We calculated the market shares for IFBA companies, globally and within nine countries--the US, China, India, Egypt, South Africa, Brazil, Mexico, Turkey and the UK. Worldwide, the top ten packaged food companies account for 15.2% of sales, with each individual company contributing less than 3.3%. The top ten soft drink companies account for 52.3% of sales worldwide; Coca-Cola and PepsiCo lead with 25.9% and 11.5% of sales, respectively. Although the top ten soft drink companies account for half of global sales, the top ten packaged food companies account for only a small proportion of market share with most individual companies contributing less than 3.3% each. Major multinational companies need to be joined by the myriad of small- and medium-sized enterprises in developing and implementing programs to improve the health of the public, globally. Without full participation of these companies, the impact of commitments made by IFBA members and other major multinational food and beverage companies will remain limited.

In 2010, as part of a national sodium reduction strategy, Canada published sodium reduction benchmark targets for packaged foods; however, no evaluation of this policy has occurred. The objective was to evaluate changes in the sodium content of packaged foods, identify categories reduced in sodium and determine the proportion meeting Health Canada’s sodium reduction benchmarks. This was a cross-sectional analysis of Canadian packaged foods in 2010 and 2013 (n=10,487 and n=15,394, respectively). Sodium content was obtained from the Nutrition Facts table. Overall, 16.2% of food categories had significantly reduced sodium levels. The greatest shifts in the distribution of sodium within food categories occurred in (mean ± standard deviation, mg/100g) imitation seafood (602±50 to 444±81, 26.2%, p=0.002), condiments (1309±790 to 1048±620, 19.9%, p=0.005), breakfast cereals (375±26 to 301±242, 19.7%, p=0.001), canned vegetables/legumes (269±156 to 217±180, 19.3%, p<0.001), plain chips (462±196 to 376±198, 18.6% p=0.004), hot cereals (453±141 to 385±155, 15.0%, p=0.011), meat analogues (612±226 to 524±177, 14.4%, p=0.003), canned condensed soup (291±62 to 250±57, 14.1%, p=0.003), and sausages and wieners (912±219 to 814±195, 10.7%, p=0.012). The proportion of foods meeting at least one of the three phases of the sodium reduction benchmark targets slightly increased (51.4% to 58.2%) and the proportion exceeding maximum benchmark levels decreased (25.2% to 20.8%). These data provide a critical evaluation of changes in sodium levels in the Canadian food supply. Although progress in reducing sodium in packaged foods is evident, the food industry needs to continue efforts in reducing the sodium in the foods they produce. PMID:27113326

The Gunion (garlic and onion) dehydration plant, owned and operated by Integrated Ingredients, a Division of Burns Philp Food, Incorporated, uses geothermal fluids at a temperature of 306{degrees}F to dehydrate 50 to 70-thousand pounds per day of garlic and onions. The geothermal fluids are provided by Empire Farms, who has the rights for development of the resource and is the lease holder of fee land known as the Kosmos Lease. The San Emidio KGRA is located in northern Washoe County, 90 miles north-northeast of Reno, Nevada and 20 miles south of Gerlach, Nevada. Geothermal fluids exit the plant at 242{degrees}Fmore » and are piped to an injection well located 3,000 feet south-southwest of the plant. The plant location was selected not only for the geothermal resource, but also for the area`s low relative humidity. Currently, 1100-1200 gpm of geothermal fluids, at an inlet temperature of 302{degrees}F, are sufficient to provide the dryer line with ample BTU`s. Three geothermal wells drilled to depths ranging from 493 to 1817 feet produce fluids ranging in temperature from 266 to 306{degrees}F. One well can easily provide the heat required by the dryer line and will be capable of providing heat for a planned three-fold expansion of the facility. The remaining two wells are used as backup, or may be used for other applications such as soil sterilization. The fluid exiting the plant at 242{degrees}F may be cascaded and used for greenhouses and soil warming in the future. Geothermal heat is also used to dehumidify onions placed in the cold storage facility. The dehydration process takes 5-6 hours to dry the product to a 4.5% moisture content. The dried product is then milled to various sizes from powder to granules. The dehydration plant operates 24 hours/day 7 days a week. Currently 80 people are employed full-time at the plant. The dehydrated onion and garlic are used in condiments, soups, sauces and salad dressing.« less

Background The 2000 Vietnamese National Nutrition Survey showed that the population's dietary intake had improved since 1987. However, inequalities were found in food consumption between socioeconomic groups. As no national data exist on the prevalence of micronutrient deficiencies, a survey was conducted in 2010 to assess the micronutrient status of randomly selected 1526 women of reproductive age and 586 children aged 6–75 mo. Principal Findings In women, according to international thresholds, prevalence of zinc deficiency (ZnD, 67.2±2.6%) and vitamin B12 deficiency (11.7±1.7%) represented public health problems, whereas prevalence of anemia (11.6±1.0%) and iron deficiency (ID, 13.7±1.1%) were considered low, and folate (<3%) and vitamin A (VAD, <2%) deficiencies were considered negligible. However, many women had marginal folate (25.1%) and vitamin A status (13.6%). Moreover, overweight (BMI≥23 kg/m2 for Asian population) or underweight occurred in 20% of women respectively highlighting the double burden of malnutrition. In children, a similar pattern was observed for ZnD (51.9±3.5%), anemia (9.1±1.4%) and ID (12.9±1.5%) whereas prevalence of marginal vitamin A status was also high (47.3±2.2%). There was a significant effect of age on anemia and ID prevalence, with the youngest age group (6–17 mo) having the highest risk for anemia, ID, ZnD and marginal vitamin A status as compared to other groups. Moreover, the poorest groups of population had a higher risk for zinc, anemia and ID. Conclusion The prevalence of anemia and ID in Vietnam has been markedly reduced over the last decade, but a large part of the population is still at risk for other deficiencies such as zinc, vitamin A, folate and vitamin B12 especially the youngest children aged 6–17 mo. Consequently specific interventions to improve food diversity and quality should be implemented, among them food fortification of staple foods and condiments and improvement of complementary feeding.

Major multinational food and beverage companies and informal sector contributions to global food consumption: implications for nutrition policy

PubMed Central

2011-01-01

Background In recent years, 10 major multinational food and beverage companies have worked together within the International Food and Beverage Alliance (IFBA) to increase their commitments to public health. Current IFBA commitments include initiatives to improve the nutrition quality of products and how these products are advertised to children. The impact and magnitude of IFBA member contributions to the total market share of packaged foods and beverages consumed remain incompletely understood, however. Methods In order to evaluate this impact, we examined packaged food and soft drink company shares provided by Euromonitor, an international independent market analysis company. Packaged foods include baby food, bakery, canned/preserved food, chilled/processed food, confectionery, dairy, dried processed food, frozen processed food, ice cream, meal replacement, noodles, oils and fats, pasta, ready meals, sauces, dressings and condiments, snack bars, soup, spreads, and sweet and savoury snacks. Soft drinks include carbonates, packaged fruit/vegetable juice, bottled water, functional drinks, concentrates, ready-to-drink tea, ready-to-drink coffee and Asian specialty drinks. We calculated the market shares for IFBA companies, globally and within nine countries--the US, China, India, Egypt, South Africa, Brazil, Mexico, Turkey and the UK. Results Worldwide, the top ten packaged food companies account for 15.2% of sales, with each individual company contributing less than 3.3%. The top ten soft drink companies account for 52.3% of sales worldwide; Coca-Cola and PepsiCo lead with 25.9% and 11.5% of sales, respectively. Conclusions Although the top ten soft drink companies account for half of global sales, the top ten packaged food companies account for only a small proportion of market share with most individual companies contributing less than 3.3% each. Major multinational companies need to be joined by the myriad of small- and medium-sized enterprises in developing and implementing programs to improve the health of the public, globally. Without full participation of these companies, the impact of commitments made by IFBA members and other major multinational food and beverage companies will remain limited. PMID:21806827

The dietary sodium-to-potassium ratio (Na:K) is shown to be more strongly associated with an increased risk of cardiovascular disease (CVD) and CVD-related mortality than either sodium or potassium intake alone. The aim was to estimate the Na:K in the diet of US adults. Among US adults from the 2011-2012 NHANES (≥20 y; 2393 men and 2337 women), the National Cancer Institute method was used to estimate sodium and potassium intakes, Na:K, and the percentage of individuals with Na:K <1.0 utilizing the complex, stratified, multistage probability cluster sampling design. Overall, women had a significantly lower Na:K than men (mean ± SE: 1.32 ± 0.02 compared with 1.45 ± 0.02). Non-Hispanic whites had a significantly lower Na:K than non-Hispanic blacks and non-Hispanic Asians (1.34 ± 0.02 compared with 1.54 ± 0.03 and 1.49 ± 0.04, respectively). Only 12.2% ± 1.5% of US adults had a Na:K < 1.0. The Na:K decreased linearly as age increased. Most adults (90% ± 0.8%) had sodium intakes >2300 mg/d, whereas <3% had potassium intakes >4700 mg/d. Grains and vegetables were among the highest contributors to sodium intakes for adults with Na:K < 1.0, compared with protein foods and grains for those with Na:K ≥ 1.0. Vegetables and milk and dairy products constituted the primary dietary sources of potassium for individuals with Na:K < 1.0, whereas mixed dishes and protein foods contributed the most potassium for individuals with ratios ≥1.0. Individuals with a Na:K < 1.0 were less likely to consume mixed dishes and condiments and were more likely to consume vegetables, milk and dairy products, and fruit than those with a Na:K ≥ 1.0. Only about one-tenth of US adults have a Na:K consistent with the WHO guidelines for reduced risk of mortality. Continued efforts to reduce sodium intake in tandem with novel strategies to increase potassium intake are warranted. © 2016 American Society for Nutrition.

Soy sauce is a traditional condiment manufactured by natural inoculation and mixed culture fermentation. As is well known, it is the microbial community that plays an important role in the formation of its flavors. However, to date, its dynamic changes during the long period of fermentation process are still unclear, intensively constraining the improvement and control of the soy sauce quality. In this work, we revealed the dynamic changes of the microbial community by combining a cultured dependent method and a cultured independent method of polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis. Results indicated that the two methods verified and complemented each other in profiling microbial community, and that significant dynamics of the microbial community existed during the fermentation process, especially the strong inhibition of the growth of most of the microbes when entering into the mash stage from the koji stage. In the analysis of bacterial community, Staphylococcus and Bacillus were found to be the dominant bacteria and detected in the whole fermentation process. Kurthia and Klebsiella began to appear in the koji stage and then fade away in the early stage of the mash fermentation. In the analysis of fungal community, Aspergillus sojae and Zygosaccharomyces rouxii were found to be the dominant fungi in the koji and mash fermentation, respectively. It was clearly shown that when A. sojae decreased and disappeared in the middle stage of the mash fermentation, Z. rouxii appeared and increased at the meantime. Aspergillus parasiticus, Trichosporon ovoides and Trichosporon asahii also appeared in the koji and the early period of the mash fermentation and disappeared thereafter. Similar to Z. rouxii, Millerozyma farinosa and Peronospora farinosa were also found spontaneously which appeared in the mid-late period of the mash fermentation. The principal component analysis suggested that the microbial community underwent significant changes in the early period of the fermentation and, thereafter, tended to the stabilization in the mid-late periods. This study gave us important clues to understand the fermentation process and can serve as a foundation for improving the quality of soy sauce in the future.

As the concern over the safety of bisphenol A (BPA) continues to grow, this compound is gradually being replaced, in industrial applications, with compounds such as bisphenol F (BPF) and bisphenol S (BPS). Occurrence of bisphenols, including BPA and BPS, has been reported in paper products and in environmental matrices. Information on the occurrence of bisphenols, other than BPA, in foodstuffs, however, is scarce. In this study, several bisphenol analogues, including BPA, BPF, and BPS, were analyzed in foodstuffs (N = 267) collected from Albany, NY, USA, using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Foodstuffs were divided into nine categories of beverages, dairy products, fats and oils, fish and seafood, cereals, meat and meat products, fruits, vegetables, and "others". Bisphenols were found in the majority (75%) of the food samples, and the total concentrations of bisphenols (ΣBPs: sum of eight bisphenols) were in the range of below the limit of quantification (LOQ) to 1130 ng/g fresh weight, with an overall mean value of 4.38 ng/g. The highest overall mean concentration of ΣBPs was found in the "others" category, which included condiments (preserved, ready-to-serve foods). A sample of mustard (dressing) and ginger, placed in the category of vegetables, contained the highest concentrations of 1130 ng/g for bisphenol F (BPF) and 237 ng/g for bisphenol P (BPP). Concentrations of BPs in beverages (mean = 0.341 ng/g) and fruits (0.698 ng/g) were low. The predominant bisphenol analogues found in foodstuffs were BPA and BPF, which accounted for 42 and 17% of the total BP concentrations, respectively. Canned foods contained higher concentrations of individual and total bisphenols in comparison to foods sold in glass, paper, or plastic containers. On the basis of measured concentrations and daily ingestion rates of foods, the daily dietary intakes of bisphenols (calculated from the mean concentration) were estimated to be 243, 142, 117, 63.6, and 58.6 ng/kg body weight (bw)/day for toddlers, infants, children, teenagers, and adults, respectively.

In 2010, as part of a national sodium reduction strategy, Canada published sodium reduction benchmark targets for packaged foods; however, no evaluation of this policy has occurred. The objective was to evaluate changes in the sodium content of packaged foods, identify categories reduced in sodium, and determine the proportion meeting Health Canada's sodium reduction benchmarks. This was a cross-sectional analysis of Canadian packaged foods in 2010 and 2013 (n = 10 487 and n = 15 394, respectively). Sodium content was obtained from the Nutrition Facts table. Overall, 16.2% of food categories had significantly reduced sodium levels. The greatest shifts in the distribution of sodium within food categories occurred in imitation seafood (mean ± SD, mg/100 g; 602 ± 50 to 444 ± 81, 26.2%, p = 0.002), condiments (1309 ± 790 to 1048 ± 620, 19.9%, p = 0.005), breakfast cereals (375 ± 26 to 301 ± 242, 19.7%, p = 0.001), canned vegetables/legumes (269 ± 156 to 217 ± 180, 19.3%, p < 0.001), plain chips (462 ± 196 to 376 ± 198, 18.6% p = 0.004), hot cereals (453 ± 141 to 385 ± 155, 15.0%, p = 0.011), meat analogues (612 ± 226 to 524 ± 177, 14.4%, p = 0.003), canned condensed soup (291 ± 62 to 250 ± 57, 14.1%, p = 0.003), and sausages and wieners (912 ± 219 to 814 ± 195, 10.7%, p = 0.012). The proportion of foods meeting at least 1 of the 3 phases of the sodium reduction benchmark targets slightly increased (51.4% to 58.2%) and the proportion exceeding maximum benchmark levels decreased (25.2% to 20.8%). These data provide a critical evaluation of changes in sodium levels in the Canadian food supply. Although progress in reducing sodium in packaged foods is evident, the food industry needs to continue efforts in reducing the sodium in the foods they produce.

This paper aims to present the author's field research data on wild food plant use in Tibetan regions. It provides a general perspective on their significance in past and present Tibet, and examines the concept of wild edible plants as medicinal plants. The fieldwork was conducted in Dhorpatan (Nepal, May-August 1998), Lithang town and surroundings (Sichuan, China, April-September 1999, May-August 2000); Southern Mustang District (Nepal, July-August 2001); and Sapi (Ladakh, Jammu and Kashmir, India, July 1995, August 2005). The research was conducted with 176 informants. The methodology included ethnographic research techniques: participant observation, open-ended conversations, semi-structured interviews, and studies of Tibetan medical texts. The author worked in the field with Tibetan colloquial and written language. The 75 total wild food plants and mushrooms belong to 36 genera and 60 species. 44 specimens are used as vegetables, 10 as spices\\condiments, 15 as fruits, 3 as ferments to prepare yoghurt and beer, 5 as substitutes for tsampa (roasted barley flour, the traditional staple food of Tibetan people), 4 as substitutes for tea, and 3 to prepare other beverages. Data from Lithang, which are more representative, show that among 30 wild food plant species exploited, 21 are consumed as vegetables, 5 as spices, 4 as fruits, 3 represent substitutes for roasted barley flour, 2 substitutes for tea, and 1 is used as fermentation agent. Tibetans have traditionally exploited few wild food plants. These mainly compensate for the lack of vegetables and fruit in traditional Tibetan diet, notably among pastoralists, and are far more important during famines as substitutes for roasted barley flour. Today few wild food plants are regularly consumed, less in the main towns and villages and moreso in remote areas and among pastoralists. Younger generations from towns have almost lost traditional botanical knowledge. Owing to modernisation and globalisation processes, many local people have specialised in collecting natural products increasingly demanded in China and abroad. Tibetan people strongly benefit from these activities. Tibetan medicine sees diet as a way of curing diseases and medical treatises describe therapeutic properties of several wild food plants that Tibetans nowadays consume.

The present study examined temporality in the representation of food in two popular British women's magazines between 1950 and 1998. A quantitative content analysis of (i) prevalence of cooking, slimming, nutrition advice in articles; (ii) prevalence of food advertising by food type; and (iii) likelihood of various nutrition and consumer messages in advertising was performed on a sample comprising 200 magazines, with 3045 advertisements and 88 articles. The prevalence of food advertisements decreased (P < 0.001), whereas food articles increased, across decades (P < 0.001). Cooking tips dominated 1950s food writing (100%), contrasting with miniscule coverage in the 1990s (5%). Slimming advice was not represented in 1950s articles and was most common in 1970s articles (55% of articles). Food advertising for all food types decreased in the 1990s decade. There were greater bread and cereals (P < 0.001), protein foods (P = 0.001) and dairy (P < 0.001) advertising in later decades; advertising for sugar- and fat-rich foods (P < 0.001), condiments and baking ingredients (P < 0.001) and beverages (P < 0.001) was greater in earlier decades. Odds of advertising claims for energy, easy digestion, nourishment, general health, economy, good for family (all P < 0.01), pleased others (P = 0.017) and convenience (P = 0.031) were greater in the 1950s and decreased thereafter. Claims around taste and quality were highest in the 1960s (all P < 0.01). Mineral, additive-free, and protein claims were most likely to be invoked in 1970s advertising (all P < 0.01). Low-fat, low-calorie and fibre claims peaked in the 1980s (all P < 0.01), whereas the odds of specific fat claims was greatest in the 1990s (P = 0.015). Representation of food resonated with prevailing food culture but was not always congruent with nutrition policy. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Initiatives to reduce sodium in packaged foods have been launched in the United States, yet corresponding changes in the amount of sodium that US households obtain from packaged foods have not been evaluated, to our knowledge. To assess 15-year changes in the amount of sodium that US households acquire from packaged food purchases, the sodium content of purchases, and the proportion of households that have purchases with optimal sodium density. Longitudinal study of US households in the 2000 to 2014 Nielsen Homescan Consumer Panel, a population-based sample of households that used barcode scanners to record all packaged foods purchased throughout the year. Time-varying brand- and product-specific nutrition information was used for 1 490 141 products. Sociodemographic-adjusted changes in mean sodium per capita (mg/d) and sodium content (mg/100 g), overall and for top food group sources of sodium, and the proportion of households that have total purchases with sodium density of 1.1 mg/kcal or less. In a nationwide sample of 172 042 US households (754 608 year-level observations), the amount of sodium that households acquired from packaged food and beverage purchases decreased significantly between 2000 and 2014 by 396 mg/d (95% CI, -407 to -385 mg/d) per capita. The sodium content of households' packaged food purchases decreased significantly during this 15-year period by 49 mg/100 g (95% CI, -50 to -48 mg/100 g), a 12.0% decline; decreases began in 2005 and continued through 2014. Moreover, the sodium content of households' purchases decreased significantly for all top food sources of sodium between 2000 and 2014, including declines of more than 100 mg/100 g for condiments, sauces, and dips (-114 mg/100 g; 95% CI, -117 to -111 mg/100 g) and salty snacks (-142 mg/100 g; 95% CI, -144 to -141 mg/100 g). However, in all years, less than 2% of US households had packaged food and beverage purchases with sodium density of 1.1 mg/kcal or less. In this nationwide study, significant reductions in sodium from packaged food purchases were achieved in the past 15 years. Nonetheless, most US households had food and beverage purchases with excessive sodium density. Findings suggest that more concerted sodium reduction efforts are needed in the United States.

In Colombia, ethnobotanical studies regarding plant cultural significance (CS) in tropical dry forests are scarce and mainly focused on the Caribbean region. Different authors have indicated that the plants with the most uses are those of greater cultural importance. Additionally, gender differences in knowledge and interest in natural resources has been widely recorded. This study evaluated the cultural significance of plants in the Doche community, in the Department of Huila. Furthermore, it evaluates the richness of plant knowledge among local inhabitants, looking for testing the hypothesis that the CS of plants positively correlates to the number of uses people inform about, and that there are significant differences on the richness of ethnobotanical knowledge between men and women in this community. The ethnobotanical categories: "food," "condiment," "economy," "fodder," "firewood," "timber", "medicine," and "others" were established to carry out semi-structured interviews, social cartography, and ethnobotanical walks. The frequency of mention was calculated as a measure of CS. The richness of knowledge of each collaborator was obtained. Non-parametric tests were performed to determine whether differences between the numbers of mentioned species existed between genders and ethnobotanical categories. Finally, Pearson correlation tests determined the relationship between CS and the number of ethnobotanical categories. A hundred useful species were registered in crops and forests. The most abundant categories were medicinal (45 species), firewood (30), and fodder (28). The most culturally significant species according to frequency of mention were Pseudosamanea guachapele, Guazuma ulmifolia, Manihot esculenta, and Musa balbisiana. The species with the most registered uses (five) were Guazuma ulmifolia and Gliricidia sepium. We found a correlation between CS and the number of uses per ethnobotanical category, but no significant difference between genders regarding ethnobotanical knowledge. Frequency of mention provides relevant information about the CS of species. Furthermore, it aids to establish sustainable use of tropical dry forests without loss of resources parting from strategies designed from within the Doche community and based on their ethnobotanical knowledge. We found that the number of uses of a plant is correlated with its degree of cultural importance. On the other hand, no significant differences were found between genders regarding ethnobotanical knowledge; that is, both men and women have similar roles in the community, which allows them to recognize the same uses per species.

Micronutrients in Pregnancy in Low- and Middle-Income Countries

Pregnancy is one of the more important periods in life when increased micronutrients, and macronutrients are most needed by the body; both for the health and well-being of the mother and for the growing foetus and newborn child. This brief review aims to identify the micronutrients (vitamins and minerals) likely to be deficient in women of reproductive age in Low- and Middle-Income Countries (LMIC), especially during pregnancy, and the impact of such deficiencies. A global prevalence of some two billion people at risk of micronutrient deficiencies, and multiple micronutrient deficiencies of many pregnant women in LMIC underline the urgency to establishing the optimal recommendations, including for delivery. It has long been recognized that adequate iron is important for best reproductive outcomes, including gestational cognitive development. Similarly, iodine and calcium have been recognized for their roles in development of the foetus/neonate. Less clear effects of deficiencies of zinc, copper, magnesium and selenium have been reported. Folate sufficiency periconceptionally is recognized both by the practice of providing folic acid in antenatal iron/folic acid supplementation and by increasing numbers of countries fortifying flours with folic acid. Other vitamins likely to be important include vitamins B12, D and A with the water-soluble vitamins generally less likely to be a problem. Epigenetic influences and the likely influence of micronutrient deficiencies on foetal origins of adult chronic diseases are currently being clarified. Micronutrients may have other more subtle, unrecognized effects. The necessity for improved diets and health and sanitation are consistently recommended, although these are not always available to many of the world’s pregnant women. Consequently, supplementation programmes, fortification of staples and condiments, and nutrition and health support need to be scaled-up, supported by social and cultural measures. Because of the life-long influences on reproductive outcomes, including inter-generational ones, both clinical and public health measures need to ensure adequate micronutrient intakes during pregnancy, but also during adolescence, the first few years of life, and during lactation. Many antenatal programmes are not currently achieving this. We aim to address the need for micronutrients during pregnancy, the importance of micronutrient deficiencies during gestation and before, and propose the scaling-up of clinical and public health approaches that achieve healthier pregnancies and improved pregnancy outcomes.

To evaluate the feasibility of implementing 3 specific prompting methods among students in the first and fourth grades (mean age = 7.2 and 10.1 years, respectively), to validate recall accuracy of first- and fourth-grade students against observation, to develop a single measure of inaccuracy that cumulated errors in reporting food items and amounts without allowing underreporting and overreporting to cancel each other, and to establish information regarding the measure of inaccuracy for use in future studies. Children were interviewed the morning after they were observed eating lunch provided by the school. Interviews included free recall, nonsuggestive prompted recall, and specific prompted recall (either preference, food category, or visual). Ninety-six children (48 students per grade) were studied--32 per the specific prompting method--stratified by grade, sex, and ethnicity (African-American or white). Specific prompting method was randomly assigned to children within strata. Food items were categorized and weighted as: combination entree = 2, condiments = 1/3, and other = 1. To calculate inaccuracy of recall, absolute differences between amounts reported and observed eaten were calculated for each item and then multiplied by each item's weight; these values were then summed across all items for each child. Inaccuracy of recall was determined before specific prompting and after specific prompting and for the difference (inaccuracy after specific prompting minus inaccuracy before specific prompting). Before specific prompting, median inaccuracy was 2.7 servings for the 48 first-grade students and 1.7 servings for the 48 fourth-grade students. The median difference in inaccuracy from before to after specific prompting was 0 for both grades. Specific prompting increased recall accuracy for 9 first-graders and 12 fourth-graders, but decreased recall accuracy for 21 first-graders and 7 fourth-graders, and did not change recall accuracy for 18 first-graders and 29 fourth-graders. Among children whose recall accuracy increased after specific prompting, 5 first-graders and 8 fourth-graders received prompting for food category. Among first-grade students, specific prompting (either preference, food category, or visual) may hurt more than help recall accuracy. Among fourth-grade students, prompting for food category yields small gains in recall accuracy with minimal losses. Validation studies are needed with larger sample sizes to determine prompting methods that produce more accurate dietary recalls from children of various socioeconomic status groups, other racial/ethnic groups, and at other meals.

The seeds of Parkia clappertoniana Keay (Family: Fabaceae) are extensively used in food in the form of a local condiment called 'Dawadawa' in Ghana and consumed by all class of people including sensitive groups such as pregnant women and children. Also, crudely pounded preparations of P. clappertoniana seeds are used as labor inducing agent in farm animals by local farmers across northern Ghana where nomadism is the livelihood of most indigenes. Ecologically, P. clappertoniana is extensively distributed across the savannah ecological zone of many African countries where just like Ghana it enjoys ethnobotanical usage. Although, many studies have investigated some aspects of the pharmacological activity of P. clappertoniana, none of these studies focused on the reproductive system, particularly its effects on reproductive performance and toxicity. To contribute, this study assessed the effect of aqueous seed extract of P. clappertoniana (PCE) on reproductive performance and toxicity in Sprague-Dawley rats and ICR mice. After preparation of PCE, it was then tested on rodents at different gestational and developmental windows (1-7, 8-14, and 15-term gestational days) to assess the following: mating behavior, implantation rate, maternal and developmental toxicities. Generally, animals were randomly grouped into five and treated as follows: normal saline group (5ml/kg po), cytotec (misoprostol) group (200mg/kg po), folic acid group (5mg/kg po), and PCE groups (100, 200, and 500mg/kg po), however, these groupings were varied to suit the specific requirements of some parameters. For acute toxicity, animals were orally administered PCE (3 and 5g/kg for mice and rats respectively). PCE-treated rats showed improved mating behavior compared to control rats. PCE improved implantation rate compared to misoprostol-treated rats. On the average, PCE-treated rats delivered termed live pubs at 21 days compared to that of folic acid-treated rats at 23 days. Also, PCE-treated rats showed no observable maternal and developmental toxicities compared to folic acid and control rats. PCE (3-5g/kg po) was orally tolerated in rodents. Oral administration of Parkia clappertoniana seed extract improves reproductive performance in rodents with no observable maternal and developmental toxicity. Copyright © 2016 Elsevier Ireland Ltd.

Ginger (Zingiber officinale Roscoe) is a common condiment for various foods and beverages and widely used worldwide as a spice. Its extracts are used extensively in the food, beverage, and confectionary industries in the production of products such as marmalade, pickles, chutney, ginger beer, ginger wine, liquors, biscuits, and other bakery products. In Ethiopia, it is among the important spices used in every kitchen to flavor stew, tea, bread and local alcoholic drinks. It is also chiefly used medicinally for indigestion, stomachache, malaria, fevers, common cold, and motion sickness. The literature survey revealed that there is no study conducted on the determination of metals in ginger cultivated in Ethiopia. Hence it is worthwhile to determine the levels of essential and non-essential metals in ginger cultivated in Ethiopia. The levels of essential (Ca, Mg, Fe, Zn, Cu, Co, Cr, Mn, and Ni) and non-essential (Cd and Pb) metals in ginger (Zingiber officinale Roscoe) cultivated in four different regions of Ethiopia and the soil where it was grown were determined by flame atomic absorption spectrometry. 0.5 g of oven dried ginger and soil samples were digested using 3 mL of HNO3 and 1 mL of HClO4 at 210°C for 3 h and a mixture of 6 mL aqua-regia and 1.5 mL H2O2 at 270°C for 3 h, respectively. The mean metal concentration (μg/g dry weight basis) ranged in the ginger and soil samples, respectively, were: Ca (2000-2540, 1770-3580), Mg (2700-4090, 1460-2440), Fe (41.8-89.0, 21700-46900), Zn (38.5-55.2, 255-412), Cu (1.1-4.8, 3.80-33.9), Co (2.0-7.6, 48.5-159), Cr (6.0-10.8, 110-163), Mn (184-401, 1760-6470), Ni (5.6-8.4, 14.1-79.3) and Cd (0.38-0.97, 0.24-1.1). The toxic metal Pb was not detected in both the ginger and soil samples. There was good correlation between some metals in ginger and soil samples while poor correlation between other metals (Fe, Ni, Cu). This study revealed that Ethiopian gingers are good source of essential metals and free from toxic metal Pb while containing negligible amount of Cd.

Maari is a spontaneously alkaline fermented food condiment made from baobab tree seeds. Due to the spontaneous nature of maari fermentations growth of the opportunistic human pathogen Bacillus cereus is occasionally observed. Bacillus subtilis strains are important for alkaline seed fermentations because of their enzymatic activities contributing to desirable texture, flavor and pH development. Some B. subtilis strains have antimicrobial properties against B. cereus. In the present work, three bacteriocin producing B. subtilis strains (B3, B122 and B222) isolated from maari were tested. The production of antimicrobial activity by the three strains was found to be greatly influenced by the substrate. All three B. subtilis strains produced antimicrobial activity against B. cereus NVH391-98 in BHI broth as determined by the agar well diffusion assay, whereas no antimicrobial activity was detected in whole cooked baobab seeds and in 10% (w/v) grinded baobab seeds. Incorporation of BHI with up to 5% (w/w) grinded baobab seeds enhanced the antimicrobial activity of B. subtilis compared with pure BHI in a strain dependent manner. Incorporation of BHI with 50% (w/w) baobab grinded seeds decreased the antimicrobial activity. Addition of the inorganic salts FeCl₃, MgSO₄ and MnSO₄ has previously been reported to increase bacteriocin production of B. subtilis, but the addition of these salts to 10% (w/v) grinded baobab seed broth did not cause antimicrobial activity. Survival of B. cereus NVH391-98 in co-culture with B. subtilis was tested in BHI broth, 10% (w/v) grinded baobab seed based broth and during baobab seed fermentation to produce maari. B. cereus NVH391-98 grew well in all three substrates in mono-culture. All the 3 B. subtilis strains were able to decrease B. cereus NVH391-98 to levels below the detection limit (<10 CFU/ml) in BHI, but not in baobab seed based substrates, even though the outgrowth of B. cereus NVH391-98 was delayed by up to 40 h. In conclusion, production of antimicrobial activity by the investigated B. subtilis strains is highly substrate-specific and strain-specific. The three B. subtilis strains delayed but did not prevent B. cereus outgrowth during baobab seed fermentations. Maari is produced through mixed microbial population fermentations. B. subtilis co-starter culture candidates originating from maari which are able to prevent pathogen outgrowth remain to be identified. Copyright © 2012 Elsevier B.V. All rights reserved.

The objectives for this experiment were to determine the effects of gamma irradiation on 1) the palatability of vacuum-packaged frozen ground beef patties by trained sensory panel and 2) consumer evaluation of the taste of hamburgers made with those patties. Boxes (4.5 kg) of frozen (-28 degrees C) ground beef patties (113.4 g/patty, 19% fat) from a commercial supplier were irradiated at a commercial gamma irradiation facility at one of three levels (0, 3.0, or 4.5 kGy). All boxes were stored at 28 degrees C for 27 to 29 d after irradiation before evaluation by a trained descriptive attribute sensory panel and for 62 to 104 d after irradiation before consumer evaluation. The trained panel evaluated grilled patties for ground beef aroma intensity, off-aroma, and off-flavor on 4-point scales (4 = intense, none, and none; 1 = none, intense, and intense, respectively) and ground beef flavor intensity, tenderness, and juiciness on 8-point scales (8 = extremely intense, tender, or juicy; 1 = extremely bland, tough, or dry). Control patties had more intense (P<.05) ground beef aroma (3.1 vs 2.6), less off-aroma (3.3 vs 2.6), and more intense ground beef flavor (4.9 vs. 4.3) than irradiated patties. However, there were no differences (P>.05) in any sensory trait between frozen ground beef patties treated with 3.0 or 4.5 kGy of gamma irradiation. There were no differences (P>.05) among treatments for tenderness (6.3, 6.6, and 6.7) or juiciness ratings (5.7, 5.9, and 5.9), respectively, for 0, 3.0, and 4.5 kGy. The consumers evaluated taste of a hamburger that included their choice of condiments on a 10-point scale (10 = excellent; 1 = terrible). Hamburgers made with patties treated with 4.5 kGy were rated lower (P<.05) in taste than hamburgers made with either control patties or those treated with 3.0 kGy (6.5, 6.6, and 6.2, respectively, for 0, 3.0, and 4.5 kGy); however, all doses were rated at some level of "fair." These results imply that hamburgers made from ground beef patties irradiated under the conditions of this experiment would encounter little, if any, consumer acceptance problems at the 3.0 kGy dose and only slightly greater problems at the 4.5 kGy dose.

Normalization can be understood as the establishing measures against repetitive situations through the development, dissemination, and application of technical design documents called standards. In Andalusia there are 45 public hospitals with 14,606 beds, and in which 11,700 full pensions / day are served. The Working Group on Hospital Food Standardization of the Andalusian Society for Clinical Nutrition and Dietetics, started in 2010, working on the certification of suppliers, product specifications, and meals technical card. - Develop a specific tool to help improving food safety through the certification of their suppliers. - Develop a standardized technical specifications of foodstuffs necessary for the development of menus established codes diets Andalusian hospitals document. - Develop a catalog of data sheets plates of hospital meals, to homogenize menus, respecting local and unifying criteria for qualitative and quantitative ingredients. - Providing documentation and studying of several public hospitals in Andalusia: • Product specifications and certification of suppliers. • International standards certification and distribution companies. • Legislation. • Data sheets for the menu items. • Specifications of different product procurement procedures. - Development of the draft standard HOSPIFOOD®, and approval of the version “0.0”. - Training course for auditors to this standard. - Development of a raw materials catalog as technical cards. - Meals Technical cards review and election of the ones which will be part of the document. After nearly three years of work, we have achieved the following products: - Standardized database of technical specifications for the production of food dietary codes for: fish, seafood, meat and meat products, meats and pates, ready meals, bread and pastries, preserves, milk and dairy products, oils, cereals, legumes , vegetables, fruits, fresh and frozen vegetables, condiments and spices. - Standardized database of technical cards for meals containing the following data: SAS Code, Province, Hospital, name plate, ingredients (g), edible ingredients (g) kcal, Proteins, HC, Fat and Fiber. - HOSPIFOOD® standard certification for food providers in hospitals, school cafeterias and other institutions of social restoration. Patients expect food that is offered during the stay in the hospital, meet basic standards of quality and safety, and therefore it is necessary to design and develop control systems from the award and / or acquisition of food (raw materials and finished) products which subsequently become part of the menu that is offered as part of their treatment. To avoid the effect of fraudulent practice in public health, it’s needed to ensure the quality and safety of the food from the origin and establish the standards for acquisition and subsequent use of it.

(-)-Hydroxycitric acid (HCA), a natural extract from the dried fruit rind of Garcinia cambogia (family Guttiferae), is a popular supplement for weight management. The dried fruit rind has been used for centuries as a condiment in Southeastern Asia to make food more filling and satisfying. A significant number of studies highlight the efficacy of Super CitriMax (HCA-SX, a novel 60% calcium-potassium salt of HCA derived from Garcinia cambogia) in weight management. These studies also demonstrate that HCA-SX promotes fat oxidation, inhibits ATP-citrate lyase (a building block for fat synthesis), and lowers the level of leptin in obese subjects. Acute oral, acute dermal, primary dermal irritation and primary eye irritation toxicity studies have demonstrated the safety of HCA-SX. However, no long-term safety of HCA-SX or any other (-)-hydroxycitric acid extract has been previously assessed. In this study, we have evaluated the dose- and time-dependent effects of HCA-SX in Sprague-Dawley rats on body weight, hepatic and testicular lipid peroxidation, DNA fragmentation, liver and testis weight, expressed as such and as a % of body weight and brain weight, and histopathological changes over a period of 90 days. The animals were treated with 0, 0.2, 2.0 and 5.0% HCA-SX as feed intake and the animals were sacrificed on 30, 60 or 90 days of treatment. The feed and water intake were assessed and correlated with the reduction in body weight. HCA-SX supplementation demonstrated a reduction in body weight in both male and female rats over a period of 90 days as compared to the corresponding control animals. An advancing age-induced marginal increase in hepatic lipid peroxidation was observed in both male and female rats as compared to the corresponding control animals. However, no such difference in hepatic DNA fragmentation and testicular lipid peroxidation and DNA fragmentation was observed. Furthermore, liver and testis weight, expressed as such and as a percentage of body weight and brain weight, at 30, 60 and 90 days of treatment, exhibited no significant difference between the four groups. Taken together, these results indicate that treatment of HCA-SX over a period of 90 days results in a reduction in body weight, but did not cause any changes in hepatic and testicular lipid peroxidation, DNA fragmentation, or histopathological changes.

R. officinalis L. is an aromatic plant commonly used as condiment and for medicinal purposes. Biological activities of its extract were evaluated in this study, as antimicrobial effect on mono- and polymicrobial biofilms, cytotoxicity, anti-inflammatory capacity, and genotoxicity. Monomicrobial biofilms of Candida albicans, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans and Pseudomonas aeruginosa and polymicrobial biofilms composed of C. albicans with each bacterium were formed in microplates during 48 h and exposed for 5 min to R. officinalis L. extract (200 mg/mL). Its cytotoxic effect was examined on murine macrophages (RAW 264.7), human gingival fibroblasts (FMM-1), human breast carcinoma cells (MCF-7), and cervical carcinoma cells (HeLa) after exposure to different concentrations of the extract, analyzed by MTT, neutral red (NR), and crystal violet (CV) assays. The anti-inflammatory activity was evaluated on RAW 264.7 non-stimulated or stimulated by lipopolysaccharide (LPS) from Escherichia coli and treated with different concentrations of the extract for 24 h. Interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were quantified by ELISA. Genotoxicity was verified by the frequency of micronuclei (MN) at 1000 cells after exposure to concentrations of the extract for 24 h. Data were analyzed by T-Test or ANOVA and Tukey Test (P ≤ 0.05). Thus, significant reductions in colony forming units per milliliter (CFU/mL) were observed in all biofilms. Regarding the cells, it was observed that concentrations ≤ 50 mg/mL provided cell viability of above 50%. Production of proinflammatory cytokines in the treated groups was similar or lower compared to the control group. The MN frequency in the groups exposed to extract was similar or less than the untreated group. It was shown that R. officinalis L. extract was effective on mono- and polymicrobial biofilms; it also provided cell viability of above 50% (at ≤ 50 mg/mL), showed anti-inflammatory effect, and was not genotoxic. Impact statement Rosmarinus officinalis L. extract effectively contributed to in vitro control of important species of microorganisms such as Candida albicans, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans, and Pseudomonas aeruginosa in mono- and polymicrobial biofilms that are responsible for several infections in oral cavity as in other regions of the body. Furthermore, this extract promoted also cell viability above 50% at concentrations ≤ 50 mg/mL, excellent anti-inflammatory effect, showing inhibition or reduction of the synthesis of proinflammatory cytokines, being also non-genotoxic to cell lines studied. Thus, this extract may be a promising therapeutic agent that can be added in some medical and dental formulations such as toothpastes, mouthwashes, irrigating root canals, ointments, soaps, in order to control pathogenic microorganisms and biofilms, with anti-inflammatory effect and absence of cytotoxic and genotoxic.

The ethnographic data presented here which demonstrate the economic role of women in exploitation of the natural environment and in the distribution of the products obtained were collected between 1978-80 in a riverine village in the state of Pahang, western Malaysia. The majority of the 64 households derive their income from traditional agriculture combined with rubber cultivation. Land in the village context is the most valued possession as a source of wealth and a basis of prestige. Only 4 households lack land; they are considered very poor. Women own 67.75 of the 166 acres devoted to rubber and 29 of the 55 plots allotted to gardening. Women, unlike men, have access to economic reserves in the form of jewelry. Women have a role in each of the principal agricultural activities of the village: kitchen gardening, exploitation of fruit trees, plantation agriculture, and rice growing. Raising of legumes and condiments in the house lot is a female activity in which men have little part. Over 1/2 of the households had an enclosed garden plot in 1978 but the size and number of cultigens varied widely, as did the skill and application of the gardeners. Fruit trees planted around the house lot were most often planted at the initiative of women, and small orchards providing fruit for sale were the responsibility of couples or of women alone. Women participated in all work in the rubber plantations except maintenance. Among the 25 households deriving most of their income from rubber culture, the work was done exclusively by women in 11 cases, by men in 10 cases, and by couples in 4 cases. Of the 10 women working alone, 6 were widowed or divorced, 1 was single, and 2 were married to invalids. Work on rubber plantations was done out of necessity by the poorest of the villagers. Rice culture, the most prestigious activity, is distinguished by the generally collective character of the work. Women predominate in the phases requiring the heaviest time investments, and of the 25 households participating, the work was done by a couple in 18 cases, by a woman alone in 6 cases, and by a man aided by other relatives in 1 case. The role of women in rice culture is evident when extra labor is needed: it is women who recruit extra workers, who are always women despite the number of idle male adolescents in the village. Until very recently the recruitment of extra workers depended more on social and personal factors than on economic needs. The circulation of cooked food is organized according to principles analogous to those of exchanges of manpower, and it is women who control the distribution. The economic role of Malaysian women is changing greatly with urbanization and the spread of plantation agriculture, and their relatively privileged position may suffer modification.

Dietary patterns (DPs) in India are heterogenous. To date, data on association of indigenous DPs in India with risk factors of nutrition-related noncommunicable diseases (cardiovascular disease and diabetes), leading causes of premature death and disability, are limited. We aimed to evaluate the associations of empirically-derived DPs with blood lipids, fasting glucose and blood pressure levels in an adult Indian population recruited across four geographical regions of India. We used cross-sectional data from the Indian Migration Study (2005-2007). Study participants included urban migrants, their rural siblings and urban residents and their urban siblings from Lucknow, Nagpur, Hyderabad and Bangalore (n = 7067, mean age 40.8 yrs). Information on diet (validated interviewer-administered, 184-item semi-quantitative food frequency questionnaire), tobacco consumption, alcohol intake, physical activity, medical history, as well as anthropometric measurements were collected. Fasting-blood samples were collected for estimation of blood lipids and glucose. Principal component analysis (PCA) was used to identify major DPs based on eigenvalue> 1 and component interpretability. Robust standard error multivariable linear regression models were used to investigate the association of DPs (tertiles) with total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides, fasting-blood glucose (FBG), systolic and diastolic blood pressure (SBP and DBP) levels. Three major DPs were identified: 'cereal-savoury' (cooked grains, rice/rice-based dishes, snacks, condiments, soups, nuts), 'fruit-vegetable-sweets-snacks' (Western cereals, vegetables, fruit, fruit juices, cooked milk products, snacks, sugars, sweets) and 'animal food' (red meat, poultry, fish/seafood, eggs) patterns. High intake of the 'animal food' pattern was positively associated with levels of TC (β = 0.10 mmol/L; 95% CI: 0.02, 0.17 mmol/L; p-trend = 0.013); LDL-C (β = 0.07 mmol/L; 95% CI: 0.004, 0.14 mmol/L; p-trend = 0.041); HDL-C (β = 0.02 mmol/L; 95% CI: 0.004, 0.04 mmol/L; p-trend = 0.016), FBG: (β = 0.09 mmol/L; 95% CI: 0.01, 0.16 mmol/L; p-trend = 0.021) SBP (β = 1.2 mm/Hg; 95% CI: 0.1, 2.3 mm/Hg; p-trend = 0.032); DBP: (β = 0.9 mm/Hg; 95% CI: 0.2, 1.5 mm/Hg; p-trend = 0.013). The 'cereal-savoury' and 'fruit-vegetable-sweets-snacks' patterns showed no association with any parameter except for a positive association with diastolic blood pressure for high intake of 'fruits-vegetables-sweets-snacks' pattern. Our results indicate positive associations of the 'animal food' pattern with cardio-metabolic risk factors in India. Further longitudinal assessments of dietary patterns in India are required to validate the findings.

The rhizome of Alpinia conchigerahas been used as a condiment in the northern states of Peninsular Malaysia and occasionally in folk medicine in the east coast to treat fungal infections. In some states of Peninsular Malaysia, the rhizomes are consumed as a post-partum medicine and the young shoots are prepared into a vegetable dish. This study aimed to investigate the chemical constituents of the pseudostems and rhizomes of Malaysian Alpinia conchigera and to evaluate the antimicrobial activity of the dichloromethane (DCM) extracts of the pseudostems, rhizomes and the isolated compounds against three selected fungi and five strains of Staphylococcus aureus. The dried and ground pseudostems (0.8kg) and rhizomes (1.0kg) were successively extracted in Soxhlet extractor using n-hexane, dichloromethane (DCM) and methanol. The n-hexane and DCM extracts of the pseudostem and rhizome were subjected to isolation and purification using column chromatography on silica gel using a stepwise gradient system (n-hexane to methanol). Briefly, a serial two fold dilutions of the test materials dissolved in DMSO were prepared prior to addition of 100μl overnight microbial suspension (108 cfu/ml) followed by incubation at 37°C (bacteria) or 26°C (dermatophytes and candida) for 24h. The highest concentration of DMSO remaining after dilution (5%, v/v) caused no inhibition to bacterial/candida/dermatophytes' growth. Antibiotic cycloheximide was used as reference for anticandidal and antidermatophyte comparison while oxacilin was used as reference for antibacterial testing. DMSO served as negative control. Turbidity was taken as indication of growth, thus the lowest concentration which remains clear after macroscopic evaluation was taken as the minimum inhibitory concentration (MIC). The isolation of n-hexane and DCM extracts of the rhizomes and pseudostems of Alpinia conchigera via column chromatography yielded two triterpenes isolated as a mixture of stigmasterol and β-sitosterol: caryophyllene oxide, chavicol acetate 1, p-hydroxy cinnamaldehyde 2, 1'S-1'-acetoxychavicol acetate 3, trans-p-coumaryl diacetate 4, 1'S-1'-acetoxyeugenol acetate 5, 1'-hydroxychavicol acetate 6, p-hydroxycinnamyl acetate 7 and 4-hydroxybenzaldehyde. The DCM extract of the rhizome of Alpinia conchigera indicated potent antifungal activity against Candida albicans, Microsporum canis and Trycophyton rubrum with MIC values of 625μg/ml, 156μg/ml and 156μg/ml, respectively. It also showed significant inhibitory activity with MIC values between 17.88 and 35.75μg/ml against the mutant Staphylococci isolates MSSA, MRSA and Sa7. Amongst the isolated compounds, the lowest inhibition observed were of 1'S-1'-acetoxyeugenol against the dermatophytes (MIC 313μg/ml) followed by trans-p-coumaryl diacetate against both dermatophytes and candida (MIC 625μg/ml). The compound p-hydroxycinnamyl acetate strongly inhibited Staphylococcusaureus strain VISA (MIC 39μg/ml) followed by trans-p-coumaryl diacetate and 1'-hydroxychavicol acetate with MIC value of 156μg/ml. In conclusion, the observed antibacterial, anticandidal and antidermatophyte activity of the extracts and compounds obtained from the rhizome confirm the traditional use of Alpinia cochigera rhizome in the treatment of skin infection.

Gary Jordan (Host): Houston we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center, episode 4, Space Food. I'm Gary Jordan and I'll be your host today. So this is the podcast where we bring in the experts, NASA scientists, engineers, astronauts, all the coolest people that tell you all the coolest parts about NASA. So today we're talking about space food with Takiyah Sirmons, she's a food scientist here at the NASA Johnson Space Center in Houston, Texas. And we had a great discussion about the science behind what astronauts eat, what it is, how they make it and how they have a long shelf life and what happens to an astronaut's palate after living in space for several months. So with no further delay let's go light speed and jump right ahead to our talk with Dr. Takiyah Sirmons, enjoy. [ Music ] Host: Okay, well Takiyah thank you so much for taking the time to come here today and talk about space food. This is one of my favorite topics because it's space food, right. Right, when you think about astronauts you think about what do they eat in space and then you have all these preconceived notions about what they eat in space. And so I thought first of all I think we should start the episode before we even get into anything by just debunking a couple of myths, right. Takiyah Sirmons: Let's debunk those myths. Host: Let's debunk it right off the bat, did NASA invent Tang? Takiyah Sirmons: NASA did not invent Tang. Tang was already in existence, it was created in the late 50s by a company called Mission Foods and we flew it in the early 60s when we were trying to figure out our food system. So John Glenn tasted Tang in space and it boosted its popularity and ever since then it's been synonymous with the space program but we did not create it, we just purchased it, repackaged it and then sent it into space. Host: See I feel like that's just always one of those things people always bring up though. They say oh Tang that's such a NASA thing and I guess they just got tied together for whatever reason. But they did use Tang. Takiyah Sirmons: We did use Tang, we still use Tang. We still use Tang until today but we did not invent it, we did not. Host: It's just because of that rehydratable, the idea that you don't have to ship up these bags of water, you can just ship up bags of powder. Takiyah Sirmons: Yah, powder flavored essentially so it's already convenient, you just put it into the beverage, package and you add water to it and you have a great flavored beverage. And it worked we don't try to reinvent the wheel here and we had a product that was on the market that was great so we just sent it. Host: All right, cool, all right there's one more that at least comes to the top of my head and you might be able to add a couple more but astronaut ice cream. Takiyah Sirmons: Oh, astronaut ice cream, that's been plaguing the crew for a long time now. So the ice cream that you see in the novelty stores with the strawberry, vanilla, chocolate swirl. We have never sent anything that is remotely like that. Host: That's what I thought, yeah. Takiyah Sirmons: Back in the Apollo days we sent ice cream one time and it was the cube form, so if you think back to tube and cube days it was a pressed food substance that was coated so it didn't have a lot of crumbs. Host: Interesting. Takiyah Sirmons: And it flew one time at the request of an astronaut and it hasn't flown since, no one else has requested it after that. From time to time the astronauts get ice cream if there is a science experiment that requires refrigeration or a freezer on the way back. We will load up the empty unit with ice cream or if it's plugged in, if it's powered up. And they'll get ice cream single serve ice cream every once in a while but it's very, very rare. Only other time that they may have had ice cream was during the sky lab days and that's because we had refrigeration and a freezer on that particular vessel. Host: That makes sense, okay. Well, I feel like those astronauts should consider themselves real lucky because they are the few that actually get to have it sometimes. >> Every once in a while. Host: Ice cream in space, so cool. Okay so it's nice to see you again after the super bowl thing that we did. Takiyah Sirmons: Yeah, that was the last time we got together. Host: Exactly, it was so fun, so they had super bowl live downtown and NASA just came up and did like a culinary event and we talked about food science. Takiyah Sirmons: Yeah. Host: We talked about you know, what we have to do different because it wasn't really a cooking show, it was like this is what NASA does even though we were preparing meals and having everyone sample them, it was pretty cool. And there is, you're not considered chefs right, you're considered food scientists because there's a whole different mindset when it comes to food in space, right? Takiyah Sirmons: Yeah, so you're taking a product that everyone is used to, everyone is familiar with food, food is very important, our emotions are tied to food and you're getting it to last for an extended period. And so I think that's where the beauty of this profession comes in, you're solving problems with an everyday product that you need, you need for life. Host: So is that kind of the main purpose of space food is your job to make the food las as long as possible or is there more to that? Takiyah Sirmons: Well, there's a nutrition component obviously so it's a prepackaged food system so imagine if you were on a diet plan and the only thing that you could have is what a company sent you in a box. You know you need to make sure it is nutritionally sound, that the calories are balanced and that it tastes good. Because if you've eaten the same product for over I want to say six months or so you're going to get tired of it. So that's where we come in to play is we want to have foods that are nutritious, that offer a wide variety but they're also appetizing at the same point. And it's a really delicate balance, a lot of people think that oh it's just food, you can just make it but it's a lot of moving parts that go into making space food. Host: Yeah, yeah, there really are so like let's just go right into it, right so space food, why are we talking now about space food versus just -- do they have a kitchen up in the International Space Station right now, what is different about space food? Like the overall concept of it? Takiyah Sirmons: The difference is that it's already prepared for you, so most of the food that they have it's a prepackaged food system like I said before so we do all of the cooking and all of the processing here on earth. We send it up and they can either reheat it in the case of thermal stabilized products that I'll guess we'll get into in a minute. Host: Sure. Takiyah Sirmons: And then they'll add water to our rehydratable products. And so all of the cooking and all of the preparation has been done for them they just need to prepare it in that moment how they're going to eat it and then if they want to remix the foods in any ways, then they have the opportunity to do that. But there's no room for a kitchen, they have a food preparation area where they can make the meals and then eat them on the go and they are also very limited in the amount of time that they have. So anything that we give them they have to be able to heat up in about 15 minutes or so and then go onto the next task. So it's not enough time in the day for them to actually cook foods. Host: Right, they have like -- what do they allot, like an hour for like lunch but they don't even allot too much time, they allot sometime in the beginning and at the end of the day but not really like -- I think they allot like an hour for lunch. Takiyah Sirmons: Yeah, yeah. Host: So that's pretty much it. Takiyah Sirmons: It's a really tight window, so I mean if you want just eat and relax during that time you don't have the time to actually prepare the food. Host: Makes sense, okay so it's not ingredients based packaging, it's meal based packaging. Takiyah Sirmons: It is meal based packaging, so we package entrees separately and then we have a number of side dishes, a number of snacks, a number of deserts and they can pick and choose from any menu of items that they want or any variety that they want. Host: So they pick and choose all the time or do they have like specific like for on this day you're going to eat this for lunch, so they don't like have meal planning. Takiyah Sirmons: No, so we put together what's called a standard menu and it's basically a suggested menu that would get them to the amount of calories that they need per day. But when they eat it's prepared pantry style, so we'll send up a container that has x amount of side dishes, x amount of entrees, x amount of vegetables and they can pick from those containers. We only as that they open one container at a time and so that's how we know if the inventory is getting low, we just assume that they've eaten everything in that container once it's opened. Host: Got it, you have to keep track so -- Takiyah Sirmons: We don't mandate that they eat according to a certain menu, we've tried that in the past and we've seen that it doesn't necessarily work. The only time that they have to eat according to a specific menu is if they are participating in a nutritional study. So they're tracking actual foods that they have and how their bodies react to that. That's the only time but that's never the entire duration of their stay. Host: Yeah, they have experiments like that, right where they're actually doing sort of like meal planning. Takiyah Sirmons: Correct they have shorter duration experimenting, during that time we'll track exactly what they eat and have to eat according to that menu but outside of that they just kind of grab what they want. Host: Okay, so that's what they do for the most part. Takiyah Sirmons: For the most part. Host: Yeah, they're just going in and having whatever they feel like having that day. I know so Peggy she got her mission extended and she's starting to get to that point where she's out there for a long time and starting to you know, the menu can only be so big, so -- what was her favorite that she just mentioned, chicken, was it chicken fajitas that was her favorite. Yeah, but you obviously have your favorites and things that are good but then you're going to have -- you can't please everyone right. It's just like any food at home right. So everyone has their preferences. Takiyah Sirmons: Everyone has their preference and after a while they start remixing meals, we make a mac and cheese product and we make a chili product and you can mix them together and make chili mac and cheese. And they do that all the time, eating the same thing for six months, you're like okay I got to find a new way to develop this product. Host: Okay, so you open up some containers and like you said they're pantry based organizations so you have like you're snacks, pet package and you have like everything, so how are the meals and you hinted at this before, like thermostabilized is one way of packaging a meal, right, so. Takiyah Sirmons: It's one way of preserving a food product, so everything that we send to the International Space Station has to be shelf-stable. We don't have refrigerators, we don't have freezers, we only have that for a short period of time during sky lab days and that was like our early stab at a space station type vehicle. Right now we don't have the power to support those type of preservations so refrigerators or freezers so everything is shelf-stable meaning that we have to preserve the foods before we send them out of earth. So the primary methods are thermostabilized which is essentially canning but in a flexible pouch. So if you've seen MRE pouches that the military uses. Host: Yeah, meals ready to eat, they're just like these brown rectangular packages. Takiyah Sirmons: Yeah, so we use the same technology, basically a canning system. So a giant pressure cooker you kill any bacteria using heat as well as pressure and -- Host: Thermostabilized [cross-talk]. Takiyah Sirmons: And so about half of our foods are produced that way and then other foods are produced the freeze drying and I think most people are familiar with freeze dried foods. You basically pull all the moisture out of a food product so that nothing can grow. And both products are great because they're light-weight, where we can pack more into our containers because they don't weigh as much and all they have to do is add the water back when they get to the space station. Host: Nice, is there a benefit to doing one versus the other for particular foods? Takiyah Sirmons: So, it depends on the foods product some can't withstand the processing for thermal processing so say if you have a product that has a lot of cheese in it you have a lot of negative effects when you apply that high of a temperature to it so those do better when you freeze dry them. And so sometimes we can try the foods both ways and you'll see which ever one comes out better. It just depends on the food product. Host: Nice, okay for the rehydratable ones, I'm guessing so since the thermostabilized, MRE you can technically just rip open the package and start eating, right. Takiyah Sirmons: You can heat them up and eat them. Host: Oh, so they do have the ability to heat them up. Takiyah Sirmons: Yeah, they have a small food warmer on station that they can put their pouches into, they don't get terribly hot but I mean it's warm enough so that you can enjoy it. Host: Okay, so it's like the space version of I guess a microwave but just not as fast maybe. Takiyah Sirmons: Yeah, exactly. Host: And then so for the freeze dried ones that one they actually have to rehydrate, right, they have to stick it in the machine that gives it water and then what do they let it sit for a while? Takiyah Sirmons: Correct, they have a rehydration station on [inaudible] and on all of our food products we tell them how much water they need to add, whether or not it's room temperature or has to be warm water. They'll inject the product and it rehydrates within 10 to 15 minutes. Again, they don't have a lot of time to wait for their products to rehydrate and then they can put it in the food warmer if they want it warmer or they could put it into a small chiller if they want it cool. And then they're able to enjoy the product that way. Host: Nice. Takiyah Sirmons: It takes a little bit longer to prepare than the thermal stabilized products but I think the quality sometimes is a lot better. Host: Interesting, okay yeah because it goes through -- okay I guess the process of that makes it actually taste better. Takiyah Sirmons: Well, the texture is preserved a little bit, if you imagine just cooking something, basically cooking it to death versus something where you pull the water out and then you add it back into the same place, it's a slightly better texture. Host: Oh, okay, see these are things I'm thinking like regular food, like cooking over a pan you know, you don't normally think about this stuff. Okay so I've seen that machine before that they use to rehydrate their meals. They have a dial like you said they can put a certain amount of liquid into it, so however many milliliters it takes to rehydrate that particular food. Takiyah Sirmons: Yes. Host: So, what foods take a little bit more water than others and why? Takiyah Sirmons: It depends, products that have obviously if you have more of a food product in the package it's going to take slightly more water. Depending on if there's sugar in the product or not that may not require as much water to rehydrate. They also adjust the amount of water that they put in so we may be do our testing on earth and say hey you need 75 milliliters, they may not like their food that watery so they'll just dial it back a little bit. So it just really depends on the product and preferences once they get into space. Host: Yeah, so I guess they just learn from experience in that kind of instance whereas it's just like oh that one was a little bit too watery for me, maybe next time I'll use the same thing because it was good but just a little bit less water. Takiyah Sirmons: Yeah, and it takes a couple of times to I guess learn the product. Host: Nice. So you work in the food lab so I'm assuming you've tried a bunch of the different meals so. Takiyah Sirmons: I like food. Host: Yeah, so what are some of your favorites? Takiyah Sirmons: I really like the meatloaf, I think it's really flavorful, it's better than the meatloaf that I make at home, I don't know if that's saying a lot. I'm really fond of anything sweet so the dessert category I'm always dipping in a dessert category, we have chocolate pudding cake, lemon carrot cake, cherry blueberry cobbler so those are probably some of my favorites. Host: I've tried the cherry blueberry cobbler. Takiyah Sirmons: Do you like that? Host: That one is really good, yes. Takiyah Sirmons: Anything sweet I think is [inaudible]. Host: So, I know in space I think it's a little bit different because I guess there's something where the astronauts over time start to lose a little bit of their taste sensitivity, so they start to enjoy spicier foods but is there a reason for that? Takiyah Sirmons: So the perception of taste changes a little bit. Number one they're in microgravity so there's a fluid shift and so it's kind of like eating with a head cold. There's still flavor there but everything is muted and so the preference for spicy foods is because you can always taste spicy food it gives you a little bit more kick. And so we always provide a variety of condiments. They have pepper on station, not in the powder form but -- not in the granulated form I'm sorry, it's dissolved in an oil so they can squeeze a drop and touch it to the product and they can spice up their foods. We have a number of hot sauce, hot sauce is always on the menu, different kinds of hot sauce. Host: I love hot sauce, I would bring so much hot sauce if I went up to orbit. Takiyah Sirmons: Well, you live in Texas [cross-talk] so a lot of hot sauce to spice up their foods. One of the favorites is shrimp cocktail because it has a spicy kick in it and I guess anything, yeah spicy food. Host: Anything spicy, yeah so how about sweet, is sweet a little bit enhanced or is the sweetness muted so they add more sugar or something like that? Takiyah Sirmons: You know, I've not heard that they add more sugar, I haven't had very many complaints about sweet products, I think it comes down to a preference if you like sweet products before you go into space you'll still have a sweet tooth when you go into space and vice-versa. Host: Okay, does preference change at all? Takiyah Sirmons: I've heard that preference does change so before any crew member goes into space they sit down with our dietician and we have one dietician on staff who essentially shows them the entire menu, so they'll work their way through all 200 different menu items. Host: Sounds like a great day, a great day. Takiyah Sirmons: They do it over several days, maybe four different times they have lunch with us and it's just so they know what to expect and they understand how the food is going to taste when they get into space. Or hopefully how it's going to taste when they get into space. They rate all the products and then items that are scored pretty high, we add those to their crew specific container which is essentially like a bonus container, it's separate from the standard menu so it's just for that particular crew member. And we do that in case they really like one item and we don't provide enough of it in the standard menu, they can have some just for themselves. Host: All right. Takiyah Sirmons: So we've heard that they come into evaluate food and they score it really high and then when they get into space they say oh I don't want this product anymore, so it's really hard to accommodate that. Host: Wow, that would stink if you had to -- if you really enjoyed one item and you're like for example the cherry blueberry cobbler and you're like oh that's my favorite dessert I'm going to have a bunch of that and then you put it in your personal and you take up all this space then you're like I really don't want it, I've had too much cherry blueberry cobbler. Takiyah Sirmons: You know what I mean, you live and you learn. Host: Yeah, I guess. Takiyah Sirmons: They trade a lot of foods on space station, so if you said you wanted one product and it doesn't taste the same when you get into space, I'm sure someone else would like that product. So it works out usually. Host: So I mean beyond preparing specifically for the International Space Station because that's where we're flying right now. You sit them down and you go through the whole menu to select what they're going to have aboard but is there any other, are there any other processes before they go up where you are preparing in a sense? Takiyah Sirmons: Preparing them for -- Host: Preparing either the meals or like how do you get ready for that, so do you sit down with the dietician and then select your meals and then you are busy preparing that food for the next couple months, like what other steps are there? Takiyah Sirmons: You mean in the lab where we prepare? Host: Yeah in the lab, yeah. Takiyah Sirmons: Oh, so we keep inventory, so like I said before all the food is packed according to category and we ask that they just open one container at a time per category. So once they've opened it, they'll scan it and we'll get a message saying hey they've opened their breakfast items which means that that is no longer in inventory. So we'll at that point go and prepare more breakfast items in the lab and have them available for the next shipment. Host: So yeah, yeah so it's more like you're watching what everyone is doing in orbit. It's not necessarily like you know, they sit down, like this is what I want and then you're preparing their meals for their orbit specifically. Takiyah Sirmons: No, no, no, no we don't do it that way because they eat according to a standard menu, no for their crew specific containers if it's something that we don't have on the menu, so say we send up granola bars, a generic form of granola bar. If you have a certain brand that you're loyal to we will go to the store and buy that brand for you as long as it's flight compatible. Meaning that it doesn't have a lot of crumbs, it's not very liquidy. It's not going to produce a lot of free liquid in space. We'll repackage it and send it into space for you so those items we will do on a case by case basis. If you say you know, I really like this brand of chocolate granola bar we will go and get that for you and package it. Host: All right, okay, I'm trying to think of other things that I would probably want to package but I'm thinking of a lot of crumby stuff so that's one thing they have to be wary of right, is because crumbs are not good to have on orbit because I guess they fly around. Takiyah Sirmons: Yeah, I mean it's a closed environment, if you don't eat it in space it's going to float around and it's going to stick somewhere. It may get stuck in your eye, it's going to get stuck in equipment, we just don't know where it's going to land to we try to avoid that we don't send chips into space for that reason but you can have crackers. Host: Oh, okay because they're less crumby, okay that makes a lot of sense. So I know another one is bread, right you can't ship bread up because bread is crumby and instead they use tortillas. Takiyah Sirmons: Right, they have tortillas and we have one type of bread product that we send up and it's extended shelf life bread and we purchase that and then we send it into space. But primarily when they want to have a sandwich or something on the go they use tortillas because it's just really convenient. Host: Yeah. Takiyah Sirmons: Yeah, so traditional bread that you find on the shelf we can't send that up, the shelf life isn't long enough and then it produces too many crumbs. Host: All right, so what else has the food lab learned just from, now that you've been flying space, flying food to space for so long, what have you sort of learned along the way. Like bread for example, thinking about crumbs, what other things have you learned along the way and kind of adapted to the menu that you have now. Takiyah Sirmons: Gees, lessons learned from flying in space. I'd like to say that the hardest thing to control is the human factor of eating in space. So like I said before we don't dictate what they eat in space because we've tried that in the past and it doesn't necessarily work. Host: Because they want to eat what they want to eat. Takiyah Sirmons: Yeah, and I mean that's a human factor that you can't control for. So you have people who are very brilliant people that are going into space but there's a psychological component that goes along with eating and when you eat something it reminds you of home, there's comfort foods that you have, you can't always mandate what someone does or doesn't want to eat. And so I think that's been one of our, I guess our biggest lessons learned. Host: So I guess it's a lot of planning then is really what the lessons come down to as you're trying to plan something diverse or if someone wants something you can deliver [inaudible]. Takiyah Sirmons: Right and that's been the driving force behind the food lab here at JSC, we started from tube and cube days and we were providing nutrition but it was very good, it wasn't very appetizing and we learned quickly that you had to provide something that at least mimicked or resembled food here on earth. And so that's what we've been doing sense the beginning of the space program when we were allowing humans to eat in space is just trying to improve it. And get something that's closer to what you normally have here on earth. Host: So I mean working with space food and designing food that has to be nutritionally balanced for the astronauts, what have you learned that you've taken into your personal life about food. Little tips and tricks that maybe us at home can take into account. Just like maybe I should have you know, I know there's a lot of fad diets out there right, so people are eliminating carbohydrates starting to eat more proteins. Or something like that, is there anything that you've learned just from creating food for astronauts on board? Takiyah Sirmons: I would say that seasonings go a very long way. Prior to coming into the food lab I seasoned everything with salt and pepper. And we had a large sodium reduction initiative in our food lab a couple years ago, we were finding that the astronauts, some of the astronauts were having vision problems from having high blood pressure in space [cross-talk]. So we reduced the sodium to reduce blood pressure and a long with that you had to reformulate a lot of your products and figure out different ways to season them. And don't under estimate the power of good seasoning, with herbs and spices and so now in my personal life I season a lot more with those. They're slightly more expensive but they go a further way than just salt and pepper. Host: So it's eliminating sodium from your or at least reducing sodium. Takiyah Sirmons: We're not eliminating it. Host: Reducing and then seasoning them with different things other than salt. Takiyah Sirmons: Yes, in my personal life I've learned how to do that. Host: Okay, all right, that's a good one, I'm going to take that one back and I'm the same way I like putting salt and pepper on everything. Because it's a good neutral seasoning and it enhances the flavor of whatever you're eating without necessarily changing it and yeah but I guess that's a bummer because I really like salt. Takiyah Sirmons: You can have your salt. Host: Okay so up on board they're going to have their preferences, right, we've been talking about this but do they share meals, right and this in an International space station, so do they share internationally? Takiyah Sirmons: So the U.S. provides about half of the food for the International Space Station and then our international partners, primarily Russia provides the other half of the foods. The astronauts that come and evaluate foods in house, they are U.S. astronauts but it's not uncommon once they get into space to begin trading food with the Russians and vice-versa. So it's a lot of trading that goes on it just kind of depends on their preference, if they see something they like then they'll try it and then they can request Russian food in their crew specific containers if they really like an item. So the next time we have a vehicle go up we can send those foods. But very common for them to trade foods amongst themselves. Because we get curious after a while. Host: Yeah, what are you guys eating, I want to know what that is, so. And they package theirs differently right, so you're talking about in the U.S. we package, thermostabilized, we do the dehydrated or what did you say, freeze dried. Takiyah Sirmons: Freeze dried foods. Host: Freeze dried foods and they do theirs in cans. Takiyah Sirmons: Yeah, they still use a can system which means that their food warmer is slightly different so they have a -- their food warmer allows you to drop the cans into a slot and they warm it that way. And our foods obviously don't fit in that particular configurations. So it's very different, the one advantage to moving to a flexible pouch which we use is that it's a light lighter so you can send more food up. Host: Oh, okay, nice yeah I do like -- it's something you have to think about right especially when you're launching things to space you got to make sure that weight is money right. Takiyah Sirmons: Yeah weight is money. Host: Yeah, so you got to reduce that and that makes a lot of sense. So going back to the lab, you know, when you're talking about sharing but you do have to prepare it and you said you're preparing -- you realize the inventory of what's on board and then prepare it that way. What's that like, what does preparing entail, like are you making dish by dish and putting them into packages. Like what's the process to get from a meal here on the ground packaged and ready to go, shipped up to the International Space Station? Takiyah Sirmons: So it's kind of a batch process, we will make maybe 100 pounds of food, 80 to 100 pounds of food depending on the process we'll determine how long it takes so with thermal stabilized foods you'll make a large kettle and then you'll put the food into individual servings sizes and so one of those collectable pouches is a serving of food. So say you take 160 grams, you'll package it, you'll seal it and then you'll put the entire batch into a retort, which is basically a giant pressure cooker. And that retort will run at a high temperature, high pressure for say an hour and then you'll take all those packages out, inspect them one by one and then they will be stored until it's time to send those. For freeze dried foods the process is a little bit longer because it can take up to a week to remove all that moisture in our freeze driers. So the process starts about the same, you'll buy ingredients from the grocery store, you'll inspect all of the ingredients. Make your batch of foods and then you'll either freeze dry them into individual servings or into one large pan, And then from there you take the pan of product and then you'll put it into individual servings, package it and then store it until you're ready to use it. So quite a long time, it is a process. Host: But you have to do that right, you can't, you've got to make sure the food is going to be good. Takiyah Sirmons: Correct. Host: When you send it up both in terms of taste obviously but in terms of quality. Takiyah Sirmons: Correct, correct. Host: Okay, so let's see we talked about shelf life, it's one of the more important things, so you're going through this process for a reason, it lasts a long time. Takiyah Sirmons: Right. Host: So what is a typical shelf life of space food? Takiyah Sirmons: Again it depends on the product, we try to have an inventory that will last for at least six months. Six months on space station, our thermostabilized foods because of the processing those can last from one year up to two year and then it can last beyond that depending on what the product is. But we definitely shoot for at least six months on space station and that just allows us enough time to prepare more foods and to get another vehicle up. Host: So what are the steps that need to happen to take it beyond that? Takiyah Sirmons: So if we needed to extend it beyond whatever shelf life we assigned it. Host: Yeah. Takiyah Sirmons: So we have a control set that we have on earth, it's housed here at JSC, anytime that we make a product and we package it we'll pull a couple samples and keep them in storage here. And so if there's a situation where we have to extend the shelf life we as a team will evaluate those products and make sure that it's till acceptable. So if I'm not going to eat it on earth, I would never ask you to eat it in space. So we don't do anything we're not willing to [inaudible]. Host: Okay, so you prepare it to last that long, you've packaged it, you've gone through that whole process what about getting it to space, how does that happen? How do you get from the lab and I guess how much do you put in a single cargo vehicle to get to space? Takiyah Sirmons: So there's no solid answer for that it really depends on how much space is available on that vehicle and what the inventory looks like on ISS. Host: So it's constantly changing. > Takiyah Sirmons: > It's constantly changing, no vehicle has the same amount of weight put into that. With that being said we don't have our own vehicle that we use, we use commercial vehicles, so Space-X and Orbital now those will dock with the International Space station, they'll unload the food and they will load up any trash or anything that needs to come back or experiments that need to come back. We don't send that on our own. Host: Oh, okay, so it changes just based on whatever you have available on that [inaudible]. Takiyah Sirmons: Yeah, it's all inventory driven so whatever is available in space that will dictate what we make on earth as well as what we package and what we send on the next vehicle. Host: But I'm assuming you have plenty of food on the International Space Station, right, so they'll never -- there's a very low chance that they'll actually runout. Takiyah Sirmons: Yeah, they'll never be in a situation where they're running out of food, they may not have all the variety that they like. They might be down to peanut butter and something they don't necessarily like but they will never runout of food. It's set up so that they have a reserve of food at all times. Host: All right, so what's some of the more creative things you've seen astronauts do with the food because you said they are prepared in a way that you can just heat them up and eat them as is because they're already meals. But are they adding stuff together and -- I mean the chili mac and cheese sounds amazing. Takiyah Sirmons: It is amazing. Host: Yeah. Takiyah Sirmons: Oh gosh I guess they make a little bit of anything, we filmed a video a couple of months ago, we had two astronauts come in and show us some of their treats and I think I was the most blown away with the space smores. They a chocolate brownie I want to say they put peanut butter paste and then cookies on the outside and I was actually really impressed with the flavor of that. And that's not anything that I would have thought of but I guess if you're in space for six months and you've been eating the same food you kind of think of different ways to consumer it. Host: Wow, if you're going to snack in space you're going to snack right, the space smore that sounds amazing. Awesome, okay so we've been talking a lot about the International Space Station and it seems like we're in a system where we're still learning and you're learning how to do different things to make it as efficient as possible and it sounds like it's very efficient right now the way that food is delivered, eaten, the whole process. But for deep space what has to change and I'm assuming shelf life is at the top of that list but you know, we've already brought down the weight so much with the freeze drying capabilities but what do we have to do to prepare for a mission to deep space and to Mars? Takiyah Sirmons: Well, your right shelf life is our number one concern. We can make foods that last two years easily, that's what we've been doing for the International Space Station. When you start talking about going to Mars you're looking at a five-year shelf life. And that's because they're have been talks of prepositioning the foods, so we launch the food ahead of the crew. The crew travels, completes the mission and then we have to have food that will last to come back. And so no one has ever done a five-year shelf life, it's not something that's necessarily desired in industry because it doesn't make money, the quicker you can turn product over the better for our food company. And so no one is really testing out to five years and so that's been a challenge for us, not only quality wise but nutritionally. We have to make sure that vitamins are stable, vitamins and minerals are stable through the entire duration of the mission so that you don't have astronauts that are malnourished at the end of their stay on Mars. You know, so that's been a challenge, that's what we're looking at now, a lot of projects that have starting now are looking at the shelf life of food up to five years. Host: So I mean you can obviously store food for long periods of time, what about a growing food? Is the food lab a part of any experiments where you're talking about planting vegetables or something like that and growing them in a different environment? Takiyah Sirmons: Well, we're not growing plants at the food lab, a lot of that work is housed out of Kennedy Space Center in Florida. And so they are growing different dwarf vegetables with the expectation that that would supplement the foods system but not necessarily be the full menu. So we still have to have a standard menu that will provide the core amount of calories. And then there's a certain amount of food that you can grow to increase their variety. And so we've partnered with them on a couple of their projects, mainly for the sensory component so seeing whether or not those products taste good and whether or not consumers can tell the difference between a product that was grown in the greenhouse versus something that you would buy in the grocery store. And so we've done a little bit of work with them on that. Host: All right, all right that sounds awesome. Takiyah Sirmons: They can have a salad in space. Host: Yeah, cut up some fresh tomatoes or something. Takiyah Sirmons: They goes a long way, if they haven't had a salad in a while then you'd be very thrilled to have one in space. Host: That is true, they did something on International Space Station recently, right the veggie experiment. Some lettuce, Scott Kelly and Kjell Lindgren and some of those guys actually got to taste it up in orbit and they said it tasted like arugula. Takiyah Sirmons: Oh, okay, arugula is tasty. Host: So it would be good for a salad right, sprinkle a little arugula on a salad, I mean I'm imagining eggs benedict right now, I'm super hungry. Takiyah Sirmons: We're not there yet. Host: One, day, one day, oh okay all right so is there anything that you've learned you know, about astronauts, just anything new. I know taste buds maybe change but is there anything that they brought down with them from their experience on orbit that has kind of changed the way that. Or maybe not exactly changed the way but just added something to the way that you process food, make food, something like that. Takiyah Sirmons: I think the preparation component has changed a little bit, we're constantly getting feedback, like we mentioned before the amount of water that it takes to rehydrate a food item. We may get feedback that says hey when we were up there it took more than 15 minutes so you guys might want to look at your formula again. Or it didn't take that much water, I had to add water, so those are things that help us improve the products for the next crew that goes up. And so we're constantly depending on astronauts for their feedback so that we can optimize any formulas that we have in house. Host: All right, cool, all right I just know from talking to different astronauts their experience with making food and eating food and it's always visually just a cool thing to watch, right because they, a lot of them end up playing with their food. Takiyah Sirmons: Playing with your food. Host: It's a very cool thing to play with, right, they bring out the different colored candies and they flow. Yeah and they flow and they're making water bubbles and drinking that, I guess are all the drinks powdered and then they have to rehydrate. Takiyah Sirmons: Yes, every drink that we send whether it's coffee, coffee with sugar or just a hint of lemon, it goes in a powder form and then they add water to it. And all of our beverages have a clamp on them, it's to prevent that bubble from floating around in space but if you want to play with your food you just remove the clamp and then over time liquid will come through the straw and start to bubble at the top, so. Host: There you go. Takiyah Sirmons: Yeah the eating experience is very different, you have to think more about it when you're in space just to make sure you're not making a mess everywhere. Host: So I mean I should have asked about that, just drinking, just coming out of a pouch, you have a straw coming out of a pouch, you have to clamp the straw otherwise -- Takiyah Sirmons: It won't happen fast but eventually over time you'll start to see a large bubble at the top and if you're not watching it then that can fall off. Host: So the bubble appears at the top of the straw and then I guess. Takiyah Sirmons: Then you can play with it. Host: You can play with it, yeah but eating though I guess we talked about making and eating but we didn't really talk about the actual process of eating. So when you open up a package is the food flying out or does it stick to the inside of the package. Takiyah Sirmons: So surface tension will keep the food in the package, it will keep it on the fork, they all have metal utensils that they use and they just clean it with wipes after they're done with the food product. Because you can't have free water, they can't wash dishes but they can sanitize and clean them. The overall experience is a little different because number one your food is floating and then you're floating in space. And so when we package food we use vel coins on the back of every product and that's so that you can literally stick it to the wall and your food doesn't float away. And so say if you're snacking while you're doing something else, you have your food product there you have your beverage there and it's stuck to one place. You can't just sit it on the table and walk away, like we have the luxury here on earth, your product will be somewhere else. Somewhere else in the space station. Host: That's interesting, you called it a vel coin? Takiyah Sirmons: Yeah a small Velcro coin. Host: Okay, like a circular, so then it sticks to that and then the food is inside the package just with the surface tension. Takiyah Sirmons: Right it stays in the package it just makes sure your food is where you left it when you turn your back. Host: Okay. And then whenever you're scooping it out with your fork or spoon or whatever it's not sticking just because you know, when you think about soup is the first thing that comes to mind. You scoop your soup and it stays at the bottom of the spoon because of gravity but because if you're scooping I don't know they probably don't have soup, do they have soup? Takiyah Sirmons: No, they have a number of soup items. They have soup, some of them have solid pieces in them so they eat them with a spoon and then we have a couple of them that it's just more of a broth and so you can drink those with a straw. So they have a number of soup products. Host: And does it stick to the -- Takiyah Sirmons: It sticks to the spoon. Host: No way it sticks to the spoon, that's really cool, awesome. All right I have so many more questions I just want to make sure that I get them all. Okay, so you're sticking it to the wall and they have like a -- I'm throwing up some air quotes here, so a dinner table right, it's just a table that's kind of diagonally against the wall but they have like tape and Velcro on it right. Takiyah Sirmons: Yeah so they can stick their food product down. And it's still a communal experience, no one wants to eat alone, unless they decide to, we don't dictate that. Host: Sometimes they're busy right. Takiyah Sirmons: Sometimes they're just busy but I mean it is set up so they can at least have the community aspect of eating, breaking bread together. Host: Breaking bread, yeah all having a meal together, that's pretty awesome. Okay, do you notice that they eat together more often or do they kind of just rush eat? Takiyah Sirmons: That I actually don't know they choose to do it one way or another. And I imagine it will depend on their schedules as well as the crew member themselves. Host: I've seen sometimes where they have an experiment and it's too vital that kind of bleeds over into their lunch time and so their lunch time is pushed to a different time and it doesn't overlap with other crew members. Takiyah Sirmons: Yeah, so they don't always eat together. Host: I was just curious on what they do in those instances, I'm assuming they just like they rehydrate their package, go do some work, come get their package, eat along the way so -- Takiyah Sirmons: Just a normal day at the office, I've had those days. Host: It's just crazy, I noticed you know, some astronauts when I was talking to them sometimes they just take that stuff for granted right, like I forget who was saying but this is not necessarily food but obviously you know, you're floating your food over on the side and working. And you're not really thinking about it. But your food is floating right next to you. I guess eventually you get in a groove when you're up there for so long that there was one astronaut talking about working out. And you know the ARED, the advanced resistance exercise that simulates weight lifting, it's positioned right, I guess if you were looking at the configuration of the International Space Station above the cupola. So when you're working out and doing bench presses you just see the earth right down -- Takiyah Sirmons: It's a beautiful sight. Host: Above you I guess it depends on -- yeah and they're taking it for granted, like awe man this workout is really hard [cross-talk] I've seen that one before, you know. I'm sure that not all of them are like that but there comes a point where you know, you're doing the same thing. They're working out two and a half hours a day, every single day. So eventually you know, things get a little bit more repetitive and I can understand it, but still very, very cool. Takiyah Sirmons: They work out a lot so they have to eat a lot, they eat a lot than you would on earth, so. Host: Oh, they do, their calories are increased? Takiyah Sirmons: They have more calories on average, and a lot of that has to do with the fact that they're working out so much and then also it takes a little bit of energy to stay upright in zero gravity. We take for granted that when we sit in a chair we want to be sitting upright, whereas they're constantly bobbing and weaving. So they have to exert that energy to stay up right. Host: There's no real sitting right, they kind of like hook their feet underneath one of those hand rails and then they have to, yeah you're right they're bobbing because they have to stay in one position unless they kind of get their footing, right. Takiyah Sirmons: Yeah. Host: Interesting, do you notice that they come down, I guess this is kind of subjective but do they come down in better shape than they went up or worse shape or how does that change? Takiyah Sirmons: It kind of depends on the person, so NASA in general they take the health of the astronaut very seriously. Host: Of course. Takiyah Sirmons: And so that is part of the reason why they workout so much, that's to combat muscle loss as well as bone loss. And so they probably work out more than they would maybe on earth, depending on the person. We try to make sure that their food is nutritionally sound so that if you're someone who is not constantly paying attention to your diet before going into space it will be an improvement for you. But a lot of them are already very health conscious. So it really depends on the person and what state they were in before, but in general we don't notice those changes as much as we used to in the past. Host: I guess that's good, right because then there's not really negative -- well, you have counter measures against those negative things. Takiyah Sirmons: Right, right. Host: So you're eating healthy, you're exercising regularly so you come down. Takiyah Sirmons: To make sure you're in reasonably good health when you come back and that's an overall mission of the space program to make sure there aren't lasting effects of going into space. And obviously the more that we have astronauts in space, the more we learn and we try to combat those effects. Host: Right and the International Space Station is perfect for that right, it's like a big you know, it's a laboratory that you can practice this over and over and then if you go do another mission then you're well-prepared because you have all this data from collected from the International Space Station, very cool. Well, Takiyah I think that's about all the time we have for the listeners if you want to know more have a suggestion on what we should talk about stay tuned to after the music to learn how to submit those ideas. Takiyah thank you so much for coming it's always a pleasure talking to you, space food is one of my favorite things to talk about. And I know we were just talking beforehand but we might have to do another episode on the history of space food. Takiyah Sirmons: That would be very interesting. Host: Yes, okay and I'm sure there's more so we'll do another episode but thank you again, it's been an absolute pleasure. Takiyah Sirmons: Thank you. [ Music ] Host: Hey, thanks for sticking around, so today we talked with Dr. Takiyah Sirmons about space food and the space food that they make is mostly right now, well almost entirely, for the International Space Station. And you can see some of the pictures that some of the astronauts share of the food that they're eating on the International space Station by going to NASA.gov/ISS. We have a lot of blog posts and photos that we release regularly, some of them are about space food but you can also learn what's going on aboard the International Space Station like what experiments they're doing and some of the latest updates on what's being done onboard. On social media we're very active on Facebook it's International Space Station, Twitter at space underscore station and on Instagram is at ISS. If you use the hashtag ask NASA on anyone of those platforms and submit an idea or maybe a question for the show we'll make sure to address it in a later episode of Houston We have a Podcast. This podcast was recorded on July 5, 2017. Thanks to Alex Perryman, John Stoll and Bill Jesse and thanks again to Dr. Takiyah Sirmons for coming on the show. We'll be back next week.
