Determination of deoxynivalenol and metabolites in maize samples by LC-MS/MS

In Vietnam, the regulation QCVN 8-1:2011/BYT has been issued to control mycotoxin content in food products. However, there are currently no regulations or studies on their derivatives and metabolites. Deoxynivalenol-3-glucoside (D3G) and two acetylated derivatives of deoxynivalenol (DON), namely 15-acetyldeoxynivalenol (15-AcDON) and 3- acetyldeoxynivalenol (3-AcDON), have been frequently detected in naturally contaminated grains such as wheat, barley, and corn. This study developed and applied a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to determine deoxynivalenol (DON) and its metabolites, including deoxynivalenol-3-glucoside (D3G), 3- acetyldeoxynivalenol (3-AcDON), and 15-acetyldeoxynivalenol (15-AcDON) in maize. The instrumental conditions comprised a C18 HSS SB (150 mm × 2.1 mm × 1.7 µm) column for separation and an MS/MS detector in positive and negative electrospray ionization (ESI) source, employing multi-reactive ion monitoring mode, with an injection volume of 2 µL. The method has been fully validated and meets the performance requirements of AOAC, demonstrating high specificity. The linearity range was established from 100 µg/kg to 1000 µg/kg, with a method detection limit (MDL) of 30 µg/kg. The repeatability and recovery rates were determined to be between 1.45% to 4.31% and 90% to 110%, respectively. The validated method was applied to analyze 50 maize samples. Deoxynivalenol (DON) was detected in 10 samples (20%), while deoxynivalenol-3-glucoside (D3G), 3- acetyldeoxynivalenol (3-AcDON), and 15-acetyldeoxynivalenol (15-AcDON) were not detected in any of the samples.

Quantitative Analysis of Sterols and Oxysterols in Foods by Gas Chromatography Coupled with Mass Spectrometry

The study aimed to determine the content of sterol oxidation products (oxysterols) in selected processed food products with the use of GC-MS. It is known that an excessively high consumption of cholesterol in foods can lead to atherosclerosis and coronary heart disease and may also promote the appearance of gallstones. Cholesterol oxidation products have mutagenic, angiotoxic and cytotoxic properties and can lead to the development of atherosclerosis and promote the occurrence of some cancers. The cholesterol content in the tested products ranged from 8.72 to 2007.11 mg/100 g fat, and plant sterols were determined in 5 out of 12 tested products and their content ranged from 5.88 to 380.8 mg/100 g fat. The studies showed the presence of sterol oxidation products in each analyzed product. The total oxysterol content ranged from 0.16 to 3.95 μg/g fat in pastry products and from 0.06 to 9.72 μg/g fat in meat products. Due to the presence of sterol oxidation products in all analyzed products, their content in food products should be monitored. The presented analytical method is a proper tool for the determination of sterol oxidation products in different food matrices.

Pemanfaatan Limbah Kulit Pisang Menjadi Pupuk Organik Cair Anti Hama Dengan Penambahan EM-4

The decomposition process of organic waste, including banana peels, can produce greenhouse gases such as methane. These gases contribute to climate change and global warming if not managed properly. One way to utilize banana peel waste is by converting it into liquid organic fertilizer, which can help farmers produce high-quality liquid organic fertilizer at an affordable price. The impact of using chemical fertilizers and pesticides includes the disruption of soil nutrient balance and pesticide residue content in food products. Based on this, research has been conducted by combining organic fertilizer material from banana peel waste with organic pesticide material from yam bean and galangal waste, thus providing a dual function as an organic fertilizer and a biopesticide in one package. This serves as an effective solution for addressing the scarcity of organic fertilizers and pesticides.

Combined Contaminant Levels from Local Harvested Food Items in the Norwegian–Finnish–Russian Border Region

This paper presents the results of a multidisciplinary study with the aim of assessing the potential combined risk from consuming locally harvested food products in the Euro-Arctic region of Norway, Finland, and Russia. The three important contaminant groups—radioactive substances, heavy metals, and persistent organic pollutants (POPs)—were measured in food samples such as berries, mushrooms, fish, birds, reindeer, and moose; they were sampled in 2013–2015. To assess the combined pollution levels and investigate the trends, similarities, and variations between different contaminant groups, subsequent multivariate statistical analysis was performed. The results showed that, in general, the levels of radioactive substances, toxic elements, and POPs were below the permitted EU maximum content in food products. However, statistical analysis revealed some correlations, similarities, and peculiarities between the accumulation of different contaminants in various species, which allowed for a better understanding of the mechanisms of accumulation and interaction between different contaminant groups. It also gave a better insight into the possible added risks and helped pinpoint species that could serve as reference markers for the accumulation of different contaminants in food. Mushrooms, fish, and reindeer were found to be important markers in the combined risk assessments for the contents of metals and radioactive substances. Further research, as well as the development of methodologies for combined assessments, are recommended.

Hygienic assessment of the consumption of trans fatty acids by the population of the Omsk region

Aim. Assessment of the content of trans-fatty acids in foods consumed by the population of the Omsk region and the values of their actual consumption.Materials and Methods. The results of laboratory studies of food products from the following groups were analyzed: fast food (hamburgers, french fries, chips); confectionery; oils, fats; meat products; dairy products (n=438). In product samples, the mass fraction of trans-fatty acid isomers was determined by gas chromatography. An assessment was made of the actual nutrition and consumption of trans fats by the inhabitants of the region using the method of analyzing the frequency of food consumption (n=441).Results. The median content of trans fats in the main food groups was 0.67% of total fat, which does not exceed the values recommended by WHO. There was a decrease in the content of trans-isomers in food products from 2.7% in the period 2016−2017. up to 1.0% in the period 2020−2021 However, there remains a significant health risk associated with the consumption of trans-fatty acids, due to the high proportion of samples exceeding the recommended levels (24.5±2.1%), to a greater extent the risk was determined by the consumption of confectionery. The median consumption of TFAs in the study population was 1.16 g, which is in line with the recommended norms. The proportion of people with excess recommended consumption was 10.2%.Conclusion. The results indicate an improvement in the situation related to the consumption of trans fats in 2016-2021 due to stricter requirements for their content in food products. It is necessary to conduct further research related to the assessment of the content of trans-isomers of fatty acids in the diet of various population groups to identify risk groups and priority food products - sources of trans fats.

Acrylamide in food products and the role of electrochemical biosensors in its detection: a comprehensive review.

In this review, the mechanisms of acrylamide formation in food, along with aspects related to its toxicity and associated consumption risks, are investigated, highlighting the potential impact on human health. European regulations regarding acrylamide content in food products are also addressed, emphasizing the importance of monitoring and detecting this substance in nutrition, by public health protection measures. The primary objective of the research is to explore and analyze innovative methods for detecting acrylamide in food, with a particular focus on electrochemical biosensors. This research direction is motivated by the need to develop rapid, sensitive, and efficient monitoring techniques for this toxic compound in food products, considering the associated consumption risks. The research has revealed several significant results. Studies have shown that electrochemical biosensors based on hemoglobin exhibited increased sensitivity and low detection limits, capable of detecting very low concentrations of acrylamide in processed foods. Additionally, it has been found that the use of functionalized nanomaterials, such as carbon nanotubes and gold nanoparticles, has led to the improvement of electrochemical biosensor performance in acrylamide detection. The integration of these technological innovations and functionalization strategies has enhanced the sensitivity, specificity, and stability of biosensors in measuring acrylamides. Thus, the results of this research offer promising perspectives for the development of precise and efficient methods for monitoring acrylamides in food, contributing to the improvement of food quality control and the protection of consumer health.

α-Lipoic acid as an ingredient of specialized food product and dietary supplement

A review of the literature in recent years was carried out using the RSCI, Google Scholar, Pubmed, and ResearchGate databases.The purpose of the review was to assess the content of α-lipoic acid (ALA) in foods and compare the doses allowed for use in dietary supplements and specialized food products with doses that provide a clinical effect. ALA or thioctic acid is synthesized in the organism and is also found in foods in free oxidized and reduced form, bound to proteins by hydrogen bonds, as well as covalently bound to lysine residues (lipoyl-lysine) in proteins, which complicates the analytical determination and reduces the bioavailability of this vitamin-like substances. Various methods for determining the natural content of individual forms (ALA and lipoyl-lysine) and their total content in food products have been described. The content of free ALA in 100 g of raw products of animal origin varies from 0.22 to 1.35 mg, of plant origin – from 0.22 to 2.04 mg. Losses during heat treatment reach 77–92%. Lipoyl–lysine content ranged from 2.11–3.99 µg/g heart, 0.56–1.17 µg/g liver, 0.71–1.40 µg/g kidney, while ALA amounts ranged from 0.22 up to 0.55 µg/g heart, from 0.38 to 0.51 µg/g liver. It is difficult to estimate the dietary intake of the total amount of all forms of ALA due to differences in extraction and detection methods. According to the domestic regulatory framework, the adequate level of ALA consumption for adults is 30 mg/day, the upper permissible level of daily consumption for adults as part of specialized food products (SFP), preventive and therapeutic nutrition and dietary supplements is 100 mg/day. ALA is often included in multicomponent dietary supplements and SPP in doses from 15 mg to 100 mg. A positive effect when taken for 10 or more weeks on lipid and carbohydrate metabolism, as well as other clinical effects in patients, is observed when taking ≥ 600 mg of ALA per day, which is significantly higher than the doses allowed for inclusion in the SFP.

Elemental Profile in Chicken Egg Components and Associated Human Health Risk Assessment.

Egg is a food product of high nutritional quality, extensively consumed worldwide. The objectives of this study were the determination of the elemental profile in eggs (egg white, yolk, and eggshell), the estimation of the non-carcinogenic health risk associated with the presence of heavy metals in investigated egg samples, and the development of statistical models to identify the best predictors for the differentiation of egg components. The assessments were carried out in a total set of 210 samples, comprising home-produced and commercial eggs, using inductively coupled plasma mass spectrometry. The results suggested measurable differences amongst hen eggs coming from different husbandry systems. The statistical models employed in this study identified several elemental markers that can be used for discriminating between market and local producer samples. The non-carcinogenic risk related to the consumption of the analyzed egg samples was generally in the safe range for the consumers, below the maximum permitted levels set by Romanian and European legislation. Food contamination is a public health problem worldwide, and the risk associated with exposure to trace metals from food products has aroused widespread concern in human health, so assessing the heavy metal content in food products is mandatory to evaluate the health risk.

Validation of the method for determining the egg albumin allergen in food products by enzyme-linked immunosorbent assay

An egg is an ecological food product containing protein, balanced vitamins, trace elements, and essential amino acids in the correct ratio. At the same time, egg albumin is an obligate allergen with no species specificity; consuming eggs from other birds does not eliminate the risk of an allergic reaction. The development of an allergy to chicken eggs in children, manifested by exudative diathesis, is especially likely. Allergy to egg protein leads to deterioration of the quality of life and health; therefore, its detection in food products is relevant today. The article contains information on the validation of the method of determining the egg protein content in food products by the enzyme-linked immunosorbent assay method and the main parameters for assessing the suitability of this method. The quantitative determination of processed chicken egg protein in food products was validated using the Ridascreen Egg ELISA test system, R-Biopharm, based on the State Research Institute for Laboratory Diagnostics and Veterinary-Sanitary Examination. The material for the study was negative samples of the matrix and enriched samples of CRM (certified reference material cake mix). Validation of the method for the quantitative determination of processed chicken egg protein in food products was carried out by determining and evaluating the following parameters: the limit of detection, quantification, convergence, reproducibility, accuracy, and uncertainty. The ELISA method for quantitatively determining processed chicken egg protein in food products has been successfully tested and meets the requirements of EU Commission Regulation 2002/657; all validation parameters are within acceptable limits. The method is suitable for food research and recommended for testing laboratories.

Initiatives to Reduce the Content of Sodium in Food Products and Meals and Improve the Population's Health.

Table salt is the main source of sodium (Na) in the human diet. Excessive supply of Na in a diet is strongly linked to many non-communicable human diseases, such as hypertension, obesity and stomach cancer. The World Health Organization recommends that daily intake of salt in adult diets should be kept below 5 g/person/day, which corresponds to 2 g Na/person/day. However, on average, adults consume about 9-10 g/person/day, and children and young people about 7-8 g/person/day. Initiatives to reduce salt intake include modifications of food composition in collaboration with the food industry, education of consumers, salt marking on foodstuff labels and taxation of salt. A need also exists to educate society so that they choose low-sodium products. In view of the food technology and amount of salt intake, the most important and the easiest change to make is to reduce the content of salt in baked goods. This paper analyses the results of surveys regarding strategies to reduce salt content in food products and considers multifaceted initiatives to reduce salt intake as a possible efficient method of improving the population's health status.

Diphenyl imidazole-based fluorescent chemosensor for Al3+ and its Al3+ complex toward water detection in food products

A sophisticated fluorescent chemosensor, 2-(4-nitrophenyl)-4,5-diphenyl-1H-imidazole (NPDI), was designed and synthesized through a one-step condensation reaction. NPDI exhibited a fluorescence enhancement response toward Al3+, accompanied by significant emission color change without interference from other tested metal ions. The binding stoichiometry and mechanism was corroborated using various techniques. The limit of detection (LOD) for Al3+ could reach 7.25 × 10−8 mol/L and the binding constant was found to be 1.47 × 105 L/mol. Furthermore, the in-situ formed NPDI·Al complex functioned a secondary chemosensor for water by quenching effect. The fluorescence quenching mechanism could be attributed to hydrogen bonding interaction of nitro substituent with water. The LOD was calculated to be 0.012 %, indicating NPDI·Al heightened sensitivity to water. Additionally, NPDI·Al complex was employed for the moisture detection in the surroundings. Finally, the practical application of NPDI·Al complex had been successfully used in the determination of water content in food products.

Evaluation of the selenium deficiency impact on metabolic parameters of people of working age

Background. Among the population living in Russia, the frequency of selenium deficiency in the body is more than 80%. An unbalanced diet in terms of the level of selenium supply to the body leads to metabolic disorders among the adult population.
 Aim. Study of the relationship between the insufficient level of selenium supply of the body in different periods of the year and changes in body composition, basal metabolism among the adult population aged 2550 years.
 Material and methods. In the autumn, winter and spring periods, the adult population aged 2550 years, living in the Leninogorsk district of the Republic of Tatarstan, of the 1st group of physical activity (n=143, of which 47% were men) was examined. The body composition was assessed using the ABC-01 Medass analyzer for bioimpedansometry. The content of selenium in the hair was studied using an atomic emission spectrometer. An assessment of the obesity and overweight prevalence in the adult population with selenium content below the reference values and the boundaries of the 95% confidence interval was made. Laboratory studies of dishes and foodstuffs for selenium content were carried out using an atomic absorption spectrometer. To assess the actual consumption of food products and dishes, the method of 24-hour (daily) reproduction of nutrition by questioning respondents on a 14-day menu was used. Statistical processing of the studied indicators was performed by the Spearman correlation method, mathematical and centile methods.
 Results. In bioassays with a low level of selenium in the hair (25 centile interval), the largest proportion of subjects with selenium deficiency was noted in autumn in more than 60% of cases, both among men with a 95% confidence interval Z-score=248, and among women with 95% confidence interval Z-score=240, while in spring only 18% and 42% at 95% confidence interval Z-score=72 and 168, respectively. When studying the relationship of selenium content in hair with morphofunctional indicators, significant correlations were found using the Spearman method with body mass index (RNovember=0.389), active cell mass (RFebruary=0.260; RMay=0.318), and basal metabolism (RMay=0.313; RNovember=0.294). Analysis of diets revealed a lack of selenium content in food products and ready-made meals in the autumn-winter period in both men (4046%, n=67) and women (5461%, n=76), in spring-summer period in 35 and 42% of cases, respectively. The lower the level of selenium in the hair (in the body), the higher the body mass index, the lower the active cell mass and the basal metabolism. There is no correlation with fat and skeletal muscle mass. The basic exchange is reduced at an insufficient of selenium supply in the body.
 Conclusion. The results indicate an insufficient intake of selenium in the body with a daily diet and the relationship of body mass index, basal metabolism with an insufficient level of selenium in the body.

The addition of dried broccoli (Brassica oleacea L.) leaves can improve the nutrition of noodles

Broccoli leaves have a high nutritional content so that they can be used as an additional ingredient in noodle products. This study aims to analyze the nutritional content of noodles with the addition of dried broccoli leaves with different percentage ratios. The treated samples were then measured proximately and all the data obtained were analyzed using ANOVA. The result showed that the highest water content, protein content, ash content and fiber content in noodles with the addition of 5% dried broccoli leaves were 39.98% water content, 14.14% protein content, 0.07% ash content and 0.62% fiber content. The highest fat and carbohydrate content in noodles added with dried broccoli leaves is on 3% of the addition. The fat content is 3.56% and the carbohydrate content is 49.56%. These findings indicate that the addition of dried broccoli leaves to noodles increases the nutritional value, especially the fiber and protein content. Broccoli leaves, which have not been used so far, can be used as food ingredients that can increase fiber and protein levels but reduce fat and carbohydrate content in food products with dried broccoli leaves added.

Evaluation of 3-MCPD content of commonly consumed food in Côte d'Ivoire using bimodal UV-Vis/electrochemistry technique

3-monochloropropane-1,2-diol (3-MCPD) is known as one of the neo-formed contaminants widely distributed in foodstuffs, especially in processed foods with high sides effects for human health. In this study, 3-monochloropropane-1,2-diol (3-MCPD) content for eleven (11) different types of foods from local market were evaluated in two ways using: (1) cysteine modified AgNPs (Cys-AgNPs) as functional nanomaterials for UV-Vis technique, and (2) gold-modified by Cys-AgNPs (Cys-AgNPs/Au) in electrochemistry sensor. High concentrations of 3-MCPD were found in most studied samples namely in liquid foods (palm oil and frying oil from tuna fish), fried foods (fried ripe banana, roasted peanut, banana chips, fried tuna and potato fries), smoked mackerel and roasted foods (pork barbecue). The maximum 3-MCPD content were 1085 μg/kg in liquid foods, 582 μg/kg in fried foods, 156 μg/kg in smoked and 716 μg/kg in roasted foods. As exhibited, the level of 3-MCPD in food products on the Ivorian market is relatively higher. This study indicates the importance of monitoring 3-MCPD content in food products for both domestic and industrial processing.

A Review of the Health Benefits of Food Enriched with Kynurenic Acid.

Kynurenic acid (KYNA), a metabolite of tryptophan, is an endogenous substance produced intracellularly by various human cells. In addition, KYNA can be synthesized by the gut microbiome and delivered in food. However, its content in food is very low and the total alimentary supply with food accounts for only 1–3% of daily KYNA excretion. The only known exception is chestnut honey, which has a higher KYNA content than other foods by at least two orders of magnitude. KYNA is readily absorbed from the gastrointestinal tract; it is not metabolized and is excreted mainly in urine. It possesses well-defined molecular targets, which allows the study and elucidation of KYNA’s role in various pathological conditions. Following a period of fascination with KYNA’s importance for the central nervous system, research into its role in the peripheral system has been expanding rapidly in recent years, bringing some exciting discoveries. KYNA does not penetrate from the peripheral circulation into the brain; hence, the following review summarizes knowledge on the peripheral consequences of KYNA administration, presents data on KYNA content in food products, in the context of its daily supply in diets, and systematizes the available pharmacokinetic data. Finally, it provides an analysis of the rationale behind enriching foods with KYNA for health-promoting effects.
