Although street foods can provide nutritious and affordable ready-to-eat meals for city dwellers, their health risks can outweigh the benefits. A cross-sectional study was conducted in the Bamako district, focusing on street food vendors near schools, universities, extensive markets, administrative centers, and major roads. We aimed to sample fifty (50) sellers per municipality, making 300 sellers for the Bamako district. We developed a survey sheet to collect data, and six teams rotated between the municipalities each month. Before starting the collection, the teams were provided administrative papers approved by the municipal authority. The survey revealed three types of sales sites: fixed (65%), semi-fixed (30%), and mobile (4.40%). The proportion of sellers was 26.8%, 23.2%, 19.7%, and 4.2% in municipalities III, IV, and I. In municipalities I, II, III, IV, and VI, respectively, 92%, 95.70%, 93%, 87.2%, and 100% of the sellers were female. The age distribution of sellers was 65.63%, 46.81%, 40.82%, 38.30%, 36.17%, 36%, and 32% in the 25-34 and 35 - 44 age groups. Illiteracy rates were 59.20%, 61.70%, 55.30%, 75%, and 56% in municipalities I, II, III, IV, and VI, respectively. The study identified two categories of sellers: 48.3% in type 1 and 51.7% in type 2. The first category comprised 154 sellers, and the second 165 sellers. The survey found that 66.00%, 56.00%, 48.90%, 44.90%, 38.30%, and 34.40% of municipal V, VI, III, I, II, and IV sales sites were open-air. In municipality I, 63.30% of the sites were under hangars, while in municipalities II and IV, the corresponding percentages were 51.10% and 59.40%, respectively. Moreover, 46.00%, 31.90%, 31.30%, 30.60%, and 27.70% of the sites in municipalities VI, II, IV, I, and III were located next to gutters. In conclusion, this study identified several factors that could compromise the quality of street foods sold in the six municipalities of Bamako.展开更多

Mixed linkage β-1.3 - 1.4 beta-glucan (beta-glucan, in this paper) is a confirmed beneficial ingredient for the human diet through reduction of cholesterol and the glycemic index. Barley contains the highest beta-glucan content of all the grains, and in this study, a percentage of flour from two high beta glucan lines was, each, added to an array of wheat-based food products to measure how it impacted total dietary fiber. Results showed that beta-glucan content was higher in all the products containing the added high beta-glucan flour, along with increased total dietary fiber content. Protein content in the food products is also increased with the higher protein in the barley flours added. Beta-glucan content in the barley-added products increased to 1.2% - 4.0% versus 0.2% - 0.5% in the pure wheat products, while the dietary fibers increased to 3.5% - 24.4% versus 2.1% - 9.1% in pure wheat product controls. This research provided experimental evidence that using a high beta-glucan barley ingredient in food can increase dietary fiber to benefit health.展开更多

Genetically modified (GM) foods have long been a controversial topic, and consumer reliance on these foods depends on their trust in biotechnology institutions due to their lack of knowledge about the risks and benefits. This study aimed to assess the awareness, attitude, and perception of GM foods among the Saudi population, as well as to identify the association between age, gender, and education level in the studied population and their awareness level towards genetically modified foods. Method: Data was collected using a structured, pretested questionnaire drawn from previous studies, after obtaining written consent. The questionnaire included three sections focusing on personal data, general knowledge of GM foods, and perception, attitudes, and beliefs towards GM foods. Our study included 500 responses. Results: The majority of the participants were female, located in the central region, and had a university education. Most participants provided a correct definition of GM foods and indicated that they had heard about them, but were unsure if they had eaten these foods in the past. Their knowledge of these foods was good. Regarding opinions and attitudes towards these foods, the majority of participants were neutral. They approved of using GM foods because it produces more food, tastes better, and can be stored for a long time. In conclusion, the study highlights the urgent necessity to raise awareness and knowledge regarding genetically modified foods among the Saudi population. It emphasizes the importance of educating consumers about the potential advantages and risks associated with consuming such foods, enabling them to make informed decisions. It is crucial to integrate awareness and education about genetically modified foods into the technological and agricultural advancements in Saudi Arabia.展开更多

Aflatoxins, a well-known mycotoxin, are mostly dangerous for both humans and livestock, according to the International Agency Cancer for Research on Cancer. In this paper, the author aimed to establish a geographical distribution map of aflatoxins fungi producers on several food like maize, maize of popcorn, popcorm, fish, spices, cassava, mil, sorghum, peanut and voandzou from the eight (8) agroecological area in Benin. Several molds were isolated from these foods and morphologically characterized on malt extract agar. Among the fungi, 318 species isolated from four leading subspecies, A. flavus, A. parasiticus, A. nomius, and A. togoensis, belonging to the Aspergillus section Flavi, were identified. For molecular analysis, polymerase chain reaction (PCR) methods were used to amplify 1450 pb of the beta-tubulin gene, and their products were used to realize restruction fragment length polymorphisms (RFLPs) to identify genic characteristics. From this strain, three DNA fragments were identified as belonging to subspecies A. flavus, and four DNA fragments were classified as belonging to A. parasiticus. Furthermore, chemotaxonomic’s analysis was performed on all strains isolated by thin layer chromatography revealing variable levels of aflatoxin’s contamination in the samples. All feedstuffs from the eight agroecological areas in Benin were found to be contaminated by several molds, and their mycotoxins mainly comprised four types of aflatoxins: B1, B2, G1 and G2. This study revealed that the four agroecological areas in northern Benin are primarily contaminated by A. flavus and A. togoensis, producers of aflatoxins B1 and B2, whereas the four agroecological areas southern Benin are contaminated by A. parasiticus and A. nomius, producers of both sets of aflatoxins B1 and B2 and aflatoxins G1 and G2. This study can be used to protect public health from the risks associated with liver cancer.展开更多

[Methods] The samples were extracted with 80% acetonitrile water(containing 0.1% formic acid), combined with QuEChERS extraction technology and C18 and PSA purification, analyzed by high performance liquid chromatography-mass spectrometry, and quantified by external standard method. The target substances were analyzed on ZORBAX Eclipse C18 chromatographic column using 0.2% formic acid water and 0.2% methanol as mobile phases. The gradient elution mode was used for chromatographic separation and multiple reaction detection. [Results] In the linear range of 0.5-50.0 ng/ml, the linear relationship of the 54 kinds of veterinary drug residues was good, with correlation coefficients(r~2) greater than 0.995, and the detection limits ranged from 0.30 to 1.00 μg/kg. The results showed that the recovery ranged from 75.4% to 118.2% when different matrixes were added for recovery. [Conclusions] This method is simple, efficient, accurate, stable, and highly operable. It is applicable to simultaneous batch screening of veterinary drug residues in animal-derived food, and has high practical application value.展开更多

However, the abusive and uncontrolled consumption of food additives is the cause of numerous illnesses and diseases such as poisoning, allergies, diabetes and numerous cancers. So, in addition to setting up control and regulatory bodies, it is becoming essential to keep a constant watch on the presence of food additives on the market. The aim of this study is to highlight the main categories of food additives in food products frequently sold on the Senegalese market. The methodology of the study is based on the identification of food additives from the information given on the labels of food packaging. Information was collected in markets in two (2) major regions of Senegal: Dakar and Saint-Louis. The results of our study show the presence of 153 food additives on the labels of 514 samples collected. Moreover, the frequency and diversity of additives depended on the food category. On the other hand, beyond their important technological and functional roles, some additives such as aspartame and monosodium glutamate have been implicated in pathologies, and others, such as titanium dioxide, are the subject of much controversy and even withdrawal in certain legislations for their impacts deemed potentially negative on consumer health.展开更多

As traditional fermented foods where lactic acid bacteria (LAB) are present have been associated with beneficial effects on human health, the beneficial effects of two LAB recently isolated from two current Ivorian staple foods (a pepper and a traditional beer) were screened. These two strains LAC 1 (Lactobacillus plantarum) and LAC 2 (Pediococcus acidilactici) which presented probiotic, exopolysaccharides, inflammatory and anti-oxidant activities, were used to ferment a composite plant milk of tiger-nut and cashew (80/20) compared to two starters of a commercial yogourt. The obtained plant milks SCT 2 and SCT 3 with a significant increase in their antioxidant and/or anti-inflammatory activities and lactic bacteria contents were more preferred by consumers than SCT 1 obtained by fermentation of the commercial yogourt starters. The mixing of LAC 1 and LAC 2 was not beneficial. SCT 2 (with an anti-inflammatory activity of 31.38% and an anti-oxidant activity of 17.30%) and SCT 3 (with an anti-oxidant activity of 22.28) could be further tested in animal models to verify their nutrition-health claims.展开更多

However, food products can potentially be contaminated by toxic heavy metals (HMs) from environmental contamination or industrial food processing. The deleterious health implications of essential trace and macro elements’ deficiency and toxic consequences of HMs in humans necessitate proactive monitoring of the essential trace elements and HMs concentrations in the humans diet to ensure public health safety. Accordingly, this study investigated a comparative analysis of essential elements and potential toxic HMs concentration in food products in the Greensboro metropolis, North Carolina, USA. A total of 49 food samples comprising of 16 difference fresh fruits, 17 fresh vegetables, 4 herbs, and 12 processed foods were purchased from local grocery stores and analyzed for iron (Fe), calcium (Ca), magnesium (Mg), nickel (Ni), zinc (Zn), copper (Cu), lead (Pb), cadmium (Cd), and chromium (Cr) by the use of flame atomic absorption spectrometry (FAAS). The concentrations of elements were subjected to a regression analysis to further gain insight of the inter-element association in the food samples. The results of the study showed high variability in the concentrations of elements in the fresh fruits, vegetables, herbs, and processed foods. The overall average concentrations of Ca (1501 μg/g), Mg (186.5 μg/g), Fe (55.8 μg/g), Zn (22.2 μg/g), Pb (10.2 μg/g), Cu (5.8 μg/g), Cr (<0.1 μg/g), Cd (<0.1 μg/g), and Ni (<0.04 μg/g) were obtained in all food samples categories. The elements concentrations were generally poorly correlated in the food samples. However, a strong inter-element association between Cu and Fe concentration (R2 = 1.000) and a weak association between Ca and Fe (R2 = 0.5609) were found in the food samples. A survey questionnaire was administered to 396 participants in the Greensboro metropolis to evaluate the food consumption pattern and a daily/weekly dietary estimate intake of vegetables, fruits, herbs and processed foods. The results of the food survey analysis showed that the amount of vegetables, fruits, herbs, and processed foods dietary intake varied widely. In general, the participants consumed more processed foods than vegetables, fruits, and herb foods. The low dietary intake of vegetables, fruits, herbs suggests that most participants may be obtaining insufficient essential trace elements and other vital nutrients necessary for normal growth and body development in their diet.展开更多

Methods: Descriptive cross-sectional study. The nutritional labeling of processed functional foods (PFF) commercially available in Honduras was examined to consider health benefits based on functionality according to the Central American Technical Regulation (CATR) and critical nutrient content according to the profile of the Panamerican Health Organization (PAHO). Results: Out of a national sample of 631 commercial processed foods (CPF), 144 were defined as functional;sweetened and flavored yogurts and cereal bars reached the highest proportions (70% and 66%) of products available in their respective categories. None of the categories was on average “low in calories” according to criteria of CATR;sweetened breakfast cereals were the most caloric (180 kcal) and only sweetened juices had “calorie free” products (15%). Prepared meat did not meet the criterion of “low cholesterol” even though all the products in this category were the reduced fat version of the original CPF. All categories of cereal-based products met the “source of dietary fiber” criteria and 64% of baked products were “high in dietary fiber”. More than 70% of PFF exceeded the sugar recommendation of the PAHO profile, mainly sweetened breakfast cereals (100%) and sweetened juices (93%). 49% of the products exceeded the sodium recommendation, particularly baked products (100%) and cheeses (86%);100% of the later exceeded the recommendation of total fats. More than 60% of products simultaneously exceeded between 2 and 3 of PAHO profile criteria;5% exceeded all the criteria and 4% met all the PAHO profile criteria. The average price of PFF was $2.34, while that of conventional products was $1.87;sweetened breakfast cereals were the most expensive ($3.49 and $3.28) and sweetened juices were the cheapest ($1.79 and $1.89) for both CPF and PFF. Conclusions: PFF marketed in Honduras have an excessive content of critical nutrients. These results demonstrate the need for a rigorous and mandatory regulation in the production, advertising and sale of functional and conventional processed foods.展开更多

In recent years, there has been growing evidence that functional foods and their bioactive compounds, due to their biological properties, may be used as complementary treatment for type 2 diabetes mellitus. In this review, we have highlighted various functional foods as missing part of medical nutrition therapy in diabetic patients. Several in vitro, animal models and some human studies, have demonstrated that functional foods and nutraceuticals may improve postprandial hyperglycemia and adipose tissue metabolism modulatecarbohydrate and lipid metabolism. Functional foods may also improve dyslipidemia and insulin resistance, and attenuate oxidative stress and inflammatory processes and subsequently could prevent the development of long-term diabetes complications including cardiovascular disease, neuropathy, nephropathy and retinopathy. In conclusion available data indicate that a functional foods-based diet may be a novel and comprehensive dietary approach for management of type 2 diabetes.展开更多

Health professionals and dietitians around the world ...Inflammatory bowel disease(IBD) is a serious health concern among western societies. The disease is also on the rise in some East Asian countries and in Australia. Health professionals and dietitians around the world are facing an unprecedented challenge to prevent and control the increasing prevalence of IBD. The current therapeutic strategy that includes drugs and biological treatments is inefficient and are associated with adverse health consequences. In this context, the use of natural products is gaining worldwide attention. In vivo studies and clinical evidence suggest that wellplanned dietary regimens with specific nutrients can alleviate gastrointestinal inflammation by modulating inflammatory cytokines, such as tumor necrosis factor α(TNF-α), interleukin 1(IL-1), IL-6, IL-1β, and IL-10. Alternatively, the avoidance of high-fat and highcarbohydrate diets is regarded as an effective tool to eliminate the causes of IBD. Many functional foods and bioactive components have received attention for showing strong therapeutic effects against IBD. Both animal and human studies suggest that bioactive functional foods can ameliorate IBD by downregulating the pro-inflammatory signaling pathways, such as nuclear factor κB, STAT1, STAT6, and pro-inflammatory cytokines, including IL-1β, IL-4, IL-6, COX-2, TNF-α, and interferon γ. Therefore, functional foods and diets have the potential to alleviate IBD by modulating the underlying pathogenic mechanisms. Future comprehensive studies are needed to corroborate the potential roles of functional foods and diets in the prevention and control of IBD.展开更多
文摘The World Health Organization states that foodborne diseases are a worldwide public health issue. Although street foods can provide nutritious and affordable ready-to-eat meals for city dwellers, their health risks can outweigh the benefits. A cross-sectional study was conducted in the Bamako district, focusing on street food vendors near schools, universities, extensive markets, administrative centers, and major roads. We aimed to sample fifty (50) sellers per municipality, making 300 sellers for the Bamako district. We developed a survey sheet to collect data, and six teams rotated between the municipalities each month. Before starting the collection, the teams were provided administrative papers approved by the municipal authority. The survey revealed three types of sales sites: fixed (65%), semi-fixed (30%), and mobile (4.40%). The proportion of sellers was 26.8%, 23.2%, 19.7%, and 4.2% in municipalities III, IV, and I. In municipalities I, II, III, IV, and VI, respectively, 92%, 95.70%, 93%, 87.2%, and 100% of the sellers were female. The age distribution of sellers was 65.63%, 46.81%, 40.82%, 38.30%, 36.17%, 36%, and 32% in the 25-34 and 35 - 44 age groups. Illiteracy rates were 59.20%, 61.70%, 55.30%, 75%, and 56% in municipalities I, II, III, IV, and VI, respectively. The study identified two categories of sellers: 48.3% in type 1 and 51.7% in type 2. The first category comprised 154 sellers, and the second 165 sellers. The survey found that 66.00%, 56.00%, 48.90%, 44.90%, 38.30%, and 34.40% of municipal V, VI, III, I, II, and IV sales sites were open-air. In municipality I, 63.30% of the sites were under hangars, while in municipalities II and IV, the corresponding percentages were 51.10% and 59.40%, respectively. Moreover, 46.00%, 31.90%, 31.30%, 30.60%, and 27.70% of the sites in municipalities VI, II, IV, I, and III were located next to gutters. In conclusion, this study identified several factors that could compromise the quality of street foods sold in the six municipalities of Bamako.
文摘Lack of dietary fiber contributes to many health issues, particularly chronic vascular diseases. Mixed linkage β-1.3 - 1.4 beta-glucan (beta-glucan, in this paper) is a confirmed beneficial ingredient for the human diet through reduction of cholesterol and the glycemic index. Barley contains the highest beta-glucan content of all the grains, and in this study, a percentage of flour from two high beta glucan lines was, each, added to an array of wheat-based food products to measure how it impacted total dietary fiber. Results showed that beta-glucan content was higher in all the products containing the added high beta-glucan flour, along with increased total dietary fiber content. Protein content in the food products is also increased with the higher protein in the barley flours added. Beta-glucan content in the barley-added products increased to 1.2% - 4.0% versus 0.2% - 0.5% in the pure wheat products, while the dietary fibers increased to 3.5% - 24.4% versus 2.1% - 9.1% in pure wheat product controls. This research provided experimental evidence that using a high beta-glucan barley ingredient in food can increase dietary fiber to benefit health.
文摘Long-term postprandial hyperglycemia is a primary risk factor for developing chronic metabolic diseases such as obesity,type 2 diabetes,and cardiovascular disease.Chronic hyperglycemia induces the glycation of proteins,oxidative stress,inflammation and increases plasma insulin and lipid concentrations.Insulin resistance is the primary cause of postprandial excursions of blood glucose and lipids.Hyperglycemia can be treated by lowering dietary carbohydrates intake,digestion,and absorption.Various functional foods improve glucose metabolism by increasing insulin sensitivity and inhibitingα-glucosidase in the small intestine.Natural phytochemicals,especially active phenolics are good antioxidants and show anti-inflammatory action and regulate blood glucose.This review aimed to report on hypoglycemic properties of active phenolics from functional foods and their proposed anti-diabetic mechanisms.Nevertheless,further clinical trials are required to confirm the bioavailability,safety,and efficacy of phenolics,especially the dosage and duration of treatment,to avoid adverse effects and give better dietary recommendations.

文摘Introduction: Recent technological developments have enabled many scientists to produce a wide variety of foods that meet consumers’ desires for diversity and quality. Genetically modified (GM) foods have long been a controversial topic, and consumer reliance on these foods depends on their trust in biotechnology institutions due to their lack of knowledge about the risks and benefits. This study aimed to assess the awareness, attitude, and perception of GM foods among the Saudi population, as well as to identify the association between age, gender, and education level in the studied population and their awareness level towards genetically modified foods. Method: Data was collected using a structured, pretested questionnaire drawn from previous studies, after obtaining written consent. The questionnaire included three sections focusing on personal data, general knowledge of GM foods, and perception, attitudes, and beliefs towards GM foods. Our study included 500 responses. Results: The majority of the participants were female, located in the central region, and had a university education. Most participants provided a correct definition of GM foods and indicated that they had heard about them, but were unsure if they had eaten these foods in the past. Their knowledge of these foods was good. Regarding opinions and attitudes towards these foods, the majority of participants were neutral. They approved of using GM foods because it produces more food, tastes better, and can be stored for a long time. In conclusion, the study highlights the urgent necessity to raise awareness and knowledge regarding genetically modified foods among the Saudi population. It emphasizes the importance of educating consumers about the potential advantages and risks associated with consuming such foods, enabling them to make informed decisions. It is crucial to integrate awareness and education about genetically modified foods into the technological and agricultural advancements in Saudi Arabia.
文摘Mycotoxins are one of the most dangerous chemical contaminants found in staple foods. Aflatoxins, a well-known mycotoxin, are mostly dangerous for both humans and livestock, according to the International Agency Cancer for Research on Cancer. In this paper, the author aimed to establish a geographical distribution map of aflatoxins fungi producers on several food like maize, maize of popcorn, popcorm, fish, spices, cassava, mil, sorghum, peanut and voandzou from the eight (8) agroecological area in Benin. Several molds were isolated from these foods and morphologically characterized on malt extract agar. Among the fungi, 318 species isolated from four leading subspecies, A. flavus, A. parasiticus, A. nomius, and A. togoensis, belonging to the Aspergillus section Flavi, were identified. For molecular analysis, polymerase chain reaction (PCR) methods were used to amplify 1450 pb of the beta-tubulin gene, and their products were used to realize restruction fragment length polymorphisms (RFLPs) to identify genic characteristics. From this strain, three DNA fragments were identified as belonging to subspecies A. flavus, and four DNA fragments were classified as belonging to A. parasiticus. Furthermore, chemotaxonomic’s analysis was performed on all strains isolated by thin layer chromatography revealing variable levels of aflatoxin’s contamination in the samples. All feedstuffs from the eight agroecological areas in Benin were found to be contaminated by several molds, and their mycotoxins mainly comprised four types of aflatoxins: B1, B2, G1 and G2. This study revealed that the four agroecological areas in northern Benin are primarily contaminated by A. flavus and A. togoensis, producers of aflatoxins B1 and B2, whereas the four agroecological areas southern Benin are contaminated by A. parasiticus and A. nomius, producers of both sets of aflatoxins B1 and B2 and aflatoxins G1 and G2. This study can be used to protect public health from the risks associated with liver cancer.
文摘This review attempts to delineate the effects and roles of fermented foods on allergic responses(AR),specifically from milk,plant,and meat sources.Evidence for AR alleviation and aggravation were noted for many different fermented food groups.Positive outcomes on AR through fermented foods could be linked to microbial hydrolysis of food allergens,improvement in gut microbiota robustness,and modulation of the immune system that promotes a balance between T helper 1(Th1)and Th2 cells.Studies on plant-based,non-protein rich fermented foods tend to show more favourable results compared to those on meat-based or protein-rich group.The usage of specific and known starter cultures are helpful in alleviating AR,as in the case for many yogurt,Kefir or Dahi products.Sufficient fermentation time was also deemed important,exemplified in studies that showed inefficient AR reduction through consumption of fresh cheese.However,formation of new allergens through fermentation of certain meat-based foods,or by using specific fermenting microbes(e.g.Penicillium sp.),is possible.Thus,combination of starter cultures and food substrates must be considered in preventing or eliminating AR from intake of these foods.This review may aid consumers to make informed decision during the consumption of fermented food.
文摘[Objectives]This study was conducted to establish a rapid and effective method for simultaneous extraction of 54 kinds of veterinary drug residues in animal-derived food, including sulfonamides, quinolones, tetracyclines, malachite greens, penicillins, nitroimidazoles, tranquilizers and macrolides, by HPLC-MS. [Methods] The samples were extracted with 80% acetonitrile water(containing 0.1% formic acid), combined with QuEChERS extraction technology and C18 and PSA purification, analyzed by high performance liquid chromatography-mass spectrometry, and quantified by external standard method. The target substances were analyzed on ZORBAX Eclipse C18 chromatographic column using 0.2% formic acid water and 0.2% methanol as mobile phases. The gradient elution mode was used for chromatographic separation and multiple reaction detection. [Results] In the linear range of 0.5-50.0 ng/ml, the linear relationship of the 54 kinds of veterinary drug residues was good, with correlation coefficients(r~2) greater than 0.995, and the detection limits ranged from 0.30 to 1.00 μg/kg. The results showed that the recovery ranged from 75.4% to 118.2% when different matrixes were added for recovery. [Conclusions] This method is simple, efficient, accurate, stable, and highly operable. It is applicable to simultaneous batch screening of veterinary drug residues in animal-derived food, and has high practical application value.
文摘Gluten,the protein responsible for the superior viscoelastic properties of refined wheat flour dough over glutenfree cereals,causes celiac disease in people susceptible to gluten-allergy.Moreover,the sustainability of using wheat flour in baked foods is threatened by its high cost,especially in countries that depend on imported wheat for their bakery industry.Research has shown that hydrocolloids serve as gluten replacements in baked foods,in response to these challenges.Food hydrocolloids are a class of high-molecular weight polysaccharides and proteins,which serve as functional ingredients in the food industry that modify the foods’rheological and textural properties.They function as stabilizers,viscosity modifiers,gelling agents,water binders,fibres,and inhibitors of ice crystal in foods.Further,food hydrocolloids have also been reported to possess health-promoting properties,such as lowering of postprandial blood glucose and plasma cholesterol concentrations,colon cancer prevention,and modulation of intestinal transit and satiety.They are obtained from plants,animals or microorganisms,and can be used in their natural or modified forms.The aim of this paper is to review the functional benefits of natural and modified hydrocolloids as gluten replacements in baked foods,emphasizing their physicochemical,nutraceutical,and sensorial importance.The application effects of food hydrocolloids as gluten substitutes in gluten-free baked products’quality were discussed.Also,some practical approaches to improve the quality of gluten-free baked products,in response to an increasing consumers’demand and the rising cost of refined wheat flour were highlighted.
文摘Food additives, whether natural or artificial substances, are widely used around the world to improve the sensory quality of products, extend their shelf life and make them more competitive. However, the abusive and uncontrolled consumption of food additives is the cause of numerous illnesses and diseases such as poisoning, allergies, diabetes and numerous cancers. So, in addition to setting up control and regulatory bodies, it is becoming essential to keep a constant watch on the presence of food additives on the market. The aim of this study is to highlight the main categories of food additives in food products frequently sold on the Senegalese market. The methodology of the study is based on the identification of food additives from the information given on the labels of food packaging. Information was collected in markets in two (2) major regions of Senegal: Dakar and Saint-Louis. The results of our study show the presence of 153 food additives on the labels of 514 samples collected. Moreover, the frequency and diversity of additives depended on the food category. On the other hand, beyond their important technological and functional roles, some additives such as aspartame and monosodium glutamate have been implicated in pathologies, and others, such as titanium dioxide, are the subject of much controversy and even withdrawal in certain legislations for their impacts deemed potentially negative on consumer health.
文摘Probiotification of plant milk can improve its sensory and health-promoting properties. As traditional fermented foods where lactic acid bacteria (LAB) are present have been associated with beneficial effects on human health, the beneficial effects of two LAB recently isolated from two current Ivorian staple foods (a pepper and a traditional beer) were screened. These two strains LAC 1 (Lactobacillus plantarum) and LAC 2 (Pediococcus acidilactici) which presented probiotic, exopolysaccharides, inflammatory and anti-oxidant activities, were used to ferment a composite plant milk of tiger-nut and cashew (80/20) compared to two starters of a commercial yogourt. The obtained plant milks SCT 2 and SCT 3 with a significant increase in their antioxidant and/or anti-inflammatory activities and lactic bacteria contents were more preferred by consumers than SCT 1 obtained by fermentation of the commercial yogourt starters. The mixing of LAC 1 and LAC 2 was not beneficial. SCT 2 (with an anti-inflammatory activity of 31.38% and an anti-oxidant activity of 17.30%) and SCT 3 (with an anti-oxidant activity of 22.28) could be further tested in animal models to verify their nutrition-health claims.
文摘In recent years,the prevalence of allergens in food warning notices,both domestically and internationally,has become the second leading concern after microbial contamination.Among the various factors that threaten human health reported by the World Health Organization,food allergy ranks fourth,and food allergy has become a global security problem.As of now,no definitive treatment for food allergies exists,making the avoidance of allergen-containing foods the most effective prevention method.Consequently,labeling foods with allergen information serves as a crucial warning for allergic populations.Moreover,to enhance comprehension of food allergies,this article provides a brief overview of their definition and sensitization mechanisms.The main focus lies in highlighting the structure of primary allergens found in eight commonly allergenic foods and the resulting clinical symptoms they cause.Additionally,a summary of commonly employed allergen detection techniques is presented,with an analysis of their principles,advantages,and limitations.Looking ahead,the integration of diverse technological approaches to establish an efficient,accurate,and affordable allergen detection method remains a significant trend.This article has certain reference value for understanding the direction of food allergies.

文摘Fermented plant-based foods and beverages constitute foods of high nutritional and functional value with appreciated health beneficial effects.They represent a natural and sustainable alternative to counteract the large wastage of vegetables and fruits due to their short shelf life.Usually,the use of controlled fermentation process using autochthonous microorganisms adapted to their vegetable matrix is preferred instead of traditionally spontaneous fermentation to designing fermented vegetable foods with the desirable sensory,technological,nutritional and functional properties.This review summarizes the autochthonous microorganisms selected as starters for the successful fermentation of vegetables and fruits.The main beneficial properties of autochthonous starters and fermented vegetable products with a focus on human health are revised.
文摘Fresh fruits, vegetables, herbs, and processed foods continue to be the major sources of essential trace elements in humans’ diet required for proper body development. However, food products can potentially be contaminated by toxic heavy metals (HMs) from environmental contamination or industrial food processing. The deleterious health implications of essential trace and macro elements’ deficiency and toxic consequences of HMs in humans necessitate proactive monitoring of the essential trace elements and HMs concentrations in the humans diet to ensure public health safety. Accordingly, this study investigated a comparative analysis of essential elements and potential toxic HMs concentration in food products in the Greensboro metropolis, North Carolina, USA. A total of 49 food samples comprising of 16 difference fresh fruits, 17 fresh vegetables, 4 herbs, and 12 processed foods were purchased from local grocery stores and analyzed for iron (Fe), calcium (Ca), magnesium (Mg), nickel (Ni), zinc (Zn), copper (Cu), lead (Pb), cadmium (Cd), and chromium (Cr) by the use of flame atomic absorption spectrometry (FAAS). The concentrations of elements were subjected to a regression analysis to further gain insight of the inter-element association in the food samples. The results of the study showed high variability in the concentrations of elements in the fresh fruits, vegetables, herbs, and processed foods. The overall average concentrations of Ca (1501 μg/g), Mg (186.5 μg/g), Fe (55.8 μg/g), Zn (22.2 μg/g), Pb (10.2 μg/g), Cu (5.8 μg/g), Cr (<0.1 μg/g), Cd (<0.1 μg/g), and Ni (<0.04 μg/g) were obtained in all food samples categories. The elements concentrations were generally poorly correlated in the food samples. However, a strong inter-element association between Cu and Fe concentration (R2 = 1.000) and a weak association between Ca and Fe (R2 = 0.5609) were found in the food samples. A survey questionnaire was administered to 396 participants in the Greensboro metropolis to evaluate the food consumption pattern and a daily/weekly dietary estimate intake of vegetables, fruits, herbs and processed foods. The results of the food survey analysis showed that the amount of vegetables, fruits, herbs, and processed foods dietary intake varied widely. In general, the participants consumed more processed foods than vegetables, fruits, and herb foods. The low dietary intake of vegetables, fruits, herbs suggests that most participants may be obtaining insufficient essential trace elements and other vital nutrients necessary for normal growth and body development in their diet.

文摘Background: Functional foods have been proposed as vehicles to prevent diseases in response to disease increase throughout the world. Methods: Descriptive cross-sectional study. The nutritional labeling of processed functional foods (PFF) commercially available in Honduras was examined to consider health benefits based on functionality according to the Central American Technical Regulation (CATR) and critical nutrient content according to the profile of the Panamerican Health Organization (PAHO). Results: Out of a national sample of 631 commercial processed foods (CPF), 144 were defined as functional;sweetened and flavored yogurts and cereal bars reached the highest proportions (70% and 66%) of products available in their respective categories. None of the categories was on average “low in calories” according to criteria of CATR;sweetened breakfast cereals were the most caloric (180 kcal) and only sweetened juices had “calorie free” products (15%). Prepared meat did not meet the criterion of “low cholesterol” even though all the products in this category were the reduced fat version of the original CPF. All categories of cereal-based products met the “source of dietary fiber” criteria and 64% of baked products were “high in dietary fiber”. More than 70% of PFF exceeded the sugar recommendation of the PAHO profile, mainly sweetened breakfast cereals (100%) and sweetened juices (93%). 49% of the products exceeded the sodium recommendation, particularly baked products (100%) and cheeses (86%);100% of the later exceeded the recommendation of total fats. More than 60% of products simultaneously exceeded between 2 and 3 of PAHO profile criteria;5% exceeded all the criteria and 4% met all the PAHO profile criteria. The average price of PFF was $2.34, while that of conventional products was $1.87;sweetened breakfast cereals were the most expensive ($3.49 and $3.28) and sweetened juices were the cheapest ($1.79 and $1.89) for both CPF and PFF. Conclusions: PFF marketed in Honduras have an excessive content of critical nutrients. These results demonstrate the need for a rigorous and mandatory regulation in the production, advertising and sale of functional and conventional processed foods.

文摘Type 2 diabetes is a complicated metabolic disorder with both short- and long-term undesirable complications. In recent years, there has been growing evidence that functional foods and their bioactive compounds, due to their biological properties, may be used as complementary treatment for type 2 diabetes mellitus. In this review, we have highlighted various functional foods as missing part of medical nutrition therapy in diabetic patients. Several in vitro, animal models and some human studies, have demonstrated that functional foods and nutraceuticals may improve postprandial hyperglycemia and adipose tissue metabolism modulatecarbohydrate and lipid metabolism. Functional foods may also improve dyslipidemia and insulin resistance, and attenuate oxidative stress and inflammatory processes and subsequently could prevent the development of long-term diabetes complications including cardiovascular disease, neuropathy, nephropathy and retinopathy. In conclusion available data indicate that a functional foods-based diet may be a novel and comprehensive dietary approach for management of type 2 diabetes.
文摘Fermented foods represent an important segment of current food markets,especially traditional or ethnic food markets.The demand for efficient utilization of agrowastes,together with advancements in fermentation technologies(microbial-and enzyme-based processing),are stimulating rapid growth and innovation in the fermented food sector.In addition,the health-promoting benefits of fermented foods are attracting increasingly attention.The microorganisms contained in many common fermented foods can serve as“microfactories”to generate nutrients and bioactives with specific nutritional and health functionalities.Herein,recent research relating to the manufacture of fermented foods are critically reviewed,placing emphasis on the potential health benefits of fermentation-enabled wellness foods.The importance of the correct selection of microorganisms and raw materials and the need for precise control of fermentation processes are explored.Major knowledge gaps and obstacles to fermented food production and market penetration are discussed.The importance of integrating multidisciplinary knowledge,communicating with consumers,establishing regulatory frameworks specifically for fermentation-enabled wellness foods and functional fermented foods,are highlighted.

文摘Inflammatory bowel disease(IBD) is a serious health concern among western societies. The disease is also on the rise in some East Asian countries and in Australia. Health professionals and dietitians around the world are facing an unprecedented challenge to prevent and control the increasing prevalence of IBD. The current therapeutic strategy that includes drugs and biological treatments is inefficient and are associated with adverse health consequences. In this context, the use of natural products is gaining worldwide attention. In vivo studies and clinical evidence suggest that wellplanned dietary regimens with specific nutrients can alleviate gastrointestinal inflammation by modulating inflammatory cytokines, such as tumor necrosis factor α(TNF-α), interleukin 1(IL-1), IL-6, IL-1β, and IL-10. Alternatively, the avoidance of high-fat and highcarbohydrate diets is regarded as an effective tool to eliminate the causes of IBD. Many functional foods and bioactive components have received attention for showing strong therapeutic effects against IBD. Both animal and human studies suggest that bioactive functional foods can ameliorate IBD by downregulating the pro-inflammatory signaling pathways, such as nuclear factor κB, STAT1, STAT6, and pro-inflammatory cytokines, including IL-1β, IL-4, IL-6, COX-2, TNF-α, and interferon γ. Therefore, functional foods and diets have the potential to alleviate IBD by modulating the underlying pathogenic mechanisms. Future comprehensive studies are needed to corroborate the potential roles of functional foods and diets in the prevention and control of IBD.
