Baby food can contain harmful components that are very dangerous to little consumers. One of the most common harmful factors is heavy metals, in particular lead. It is known that introducing one extra microelement into the body changes not only the concentration of this element, but also the concentration of other elements. Disturbing the physiological balance of microelements leads to changes in complex enzymatic processes, which in turn violates the structure of tissue cells of individual organs. Studies by Russian scientists (T. Suldina and others) have determined, in milk for newborns, the maximum levels of lead (0.02 mg/kg), of cadmium (0.02 mg/kg), of arsenic (0.05 mg/kg). While studying certain samples of baby food, the method for determining the content of lead and other heavy metals was improved. Depending on the lead concentration, characteristic lines of both the ultraviolet and the visible spectral regions can be used. Monitoring heavy metals in infant milk has shown that lead, copper, and zinc are the main contaminants of the product. The concentration of toxic agents in baby milk depends on the type of raw materials and on the environmental conditions of their manufacture. To detect lead in products quickly and accurately, a method was used based on the emission spectral analysis. To this end, spectrographs ISP-28 and ISP-30 widely employed in industry and laboratory studies were taken, but the detection limits were lowered compared to those in the methods that had been used previously. Besides, the field-proven method for determining lead is applicable to detecting zinc and copper, too. An excess of lead by 0.08 mg/kg, copper by 0.07 mg/kg, zinc by 0.45 mg/kg was observed in the baby milk “Malyatko Premium 2.” In the milk “Bellakt 2,” the excessive amount of copper was 0.05 mg/kg, of zinc 0.20 mg/kg, of lead 0.05 mg/kg. In the baby milk “Nitricia Malyuk Istrynsky,” only zinc was found to exceed the normal level (by 0.1 mg/kg). The baby milks “Nutricia Milupa 2,” “Nestle Nestogen 2,” “HiPP Organic 2” do not contain excessive heavy metals, and thus, can be recommended as safe for consumption.

The results of studying the effects of water-alcohol infusions of medicinal plants - rhizomes of thick-leafed incense (Bergenia crasslifolia L. Fritsch), dioica nettle leaves (Urtica dioca L.), burdock roots (Arctium lappa L.), and mother-and-leaf leaves - are presented. ordinary machichi (Tussilago farfara L.) on the organism of laboratory rats under conditions of short-term intoxication with heavy metals in doses of 25 mg of lead and 2.5 mg of cadmium per 1 kg of live weight. In the course of studies it was found that the effect of heavy metals on the body of laboratory animals is selective - the main “depot” of lead was bone tissue, and cadmium - the kidneys and liver. The addition of 1 ml of water-alcohol infusions from medicinal raw materials to the diet of rats as detoxicants caused a decrease in the level of lead in the animal organism to 6.32 times, cadmium to 3.46 times. The greatest detoxification ability was shown by infusions of the roots of burdock and leaves of nettle dioecious. Under the influence of elevated doses of lead and cadmium in laboratory animals there was an increase in heart mass by 40.34 % and spleen by 89.91 %, a decrease in the content of alkaline phosphatase in blood serum by 25.81 %. Water-alcohol infusions normalized the biochemical parameters of rat blood serum. Studies have shown that the infusions of rhizomes of thick-leafed frangipani, burdock roots, dioecious nettles and coltsfoot leaves with antioxidant properties can be the basis for the development of an effective herbal preparation used for the prevention and treatment of animals from intoxication with salts of heavy metals.

Subjects of the research: soils, pasture and cultivated plants, vegetable raw materials, prepared feed of the raw material zone of the Branch of the Tikhoretsky Children's Meat Canning Plant of DANON-RUSSIA JSC. The quantitative content of mobile forms of heavy metals in soils under the main feed crops and their accumulation in finished feeds was determined. The a soil with a high humus content cover in the area of the surveyed farms is mainly represented by carbonate weakly humus heavy-duty “chernozem”, which occupies 82.5 % of all land. Fodder raw materials in the autumn-winter season 2019-2020 is safe in quantitative content regulated by standards of elements of heavy metals. Their contents were established: mercury ≤ 0.01 mg / kg, cadmium ≤ 0.2 mg / kg, lead ≤ 2.0 mg / kg and arsenic ≤ 0.5 mg / kg. However, there was an insignificant (1-2%) increase in the zinc content in the silage from the green mass of corn and haylage from the green mass of alfalfa. It was established that the remains of the prohibited pesticides are in trace amounts or practically absent in the feed of the raw material zone. The monitoring results will be used in farms - suppliers of beef for the production of baby food - canned meat and meat and vegetable.

Introduction. Changes in the body of children and adolescents aimed at adapting to environmental factors are determined by genetic polymorphism in xenobiotic biotransformation genes, determining the degree of susceptibility of the child’s body to pollutants, which is the basis of modern personalized preventive medicine when managing risks to the health of the child population under the influence of environmental factors. Material and methods. Trace elements, including heavy metals, lead and cadmium, were determined in the hair of 256 practically healthy teenagers by atomic absorption spectrophotometry. Depending on the level of content of the latter, two groups of adolescents were formed to determine six genes of the cytochrome P-450 family. Group 1 consisted of adolescents whose cadmium lead content exceeded the average Russian indices. The second group included adolescents whose heavy metals were above the level of average Russian standards. Results. Studies have shown that in adolescents of the 1st group, compared with the data of adolescents of the 2nd group, an increase in the number of carriers of two mutant alleles at the locus rs 1048943 (gene CYP1A1) is 3.08 times, rs 464621 (gene CYP1A1) is 1. 8 times; locus rs 2069522 (CYP1A2 gene) 3.63 times; locus rs 1799853 (CYP2C9 * 2 gene) 4.5 times; locus rs 1057910 (gene CYP2C9 * 3) 3.8 times and locus rs 2279343 (gene CYP2B6) 4.25 times. Moreover, carriers of two normal alleles in adolescents of the first group at the locus rs 1048943 (gene CYP1A1) were 5.14 times; locus rs 2279343 (CYP2B6 gene) was 6.5 fold less than among adolescents of the 2nd group; and at the locus rs 464621 (gene CYP1A1), rs 2069522 (gene CYP1A2), rs 1799853 (gene CYP2C9 * 2), rs 1057910 (gene CYP2C9 * 3) there were no carriers of normal homozygotes. Conclusion. Group 1 adolescents with heavy metal contamination of the body are carriers significantly in a greater number of pathological mutations in the genes of the cytochrome P-450 detoxification system in comparison with data from group 2 adolescents.

In this research work the concentration of zinc, copper, lead, chromium, cadmium, and nickel in cow milk samples obtained from four different grazing areas   (kakuri, kudendan, malali, kawo) of Kaduna metropolis. The samples were digested by wet digestion technique .The trace element were determined using bulk scientific model VPG 210 model  Atomic Absorption Spectrophotometer (AAS).. The concentration of the determined heavy metal were The result revealed that Cr,  Ni and Cd were not detected in milk samples from Kawo, Malali  and Kudendan whereas lead (Pb) is detected in all samples and found to be above  the stipulated limits of recommended dietary allowance (NRC,1989) given as 0.02mg/day. Cu and Zn are essential elements needed by the body for proper metabolism and as such their deficiency or excess is very dangerous for human health. However, they were found in all samples and are within the recommended limits while Cd (2.13 – 3.15 mg/kg) in milk samples from Kakuri was found to be above such limit (0.5mg/day). Cow milk samples analyzed for heavy metals in this research work pose a threat of lead and cadmium toxicity due to their exposure to direct sources of air, water and plants in these grazing areas, thereby, resulting to a potential health risk to the consumers.

Abstract The inclusion of polysaccharide thickeners in the recipes of sweet dishes increases the functional reserves of the body, contributes to the preservation of health and the prevention of diseases. The purpose of the research is to study the sensory characteristics of polysaccharides of various nature when combined with food acids, to develop a recipe for a basic mixture of low-calorie meals for public catering. The authors analyzed citric, lactic and succinic acids in combinations with polysaccharides of various nature. Organoleptic tests were evaluated by a touch panel. The organization of the tasting analysis corresponded to GOST ISO 6658-2016; the consistency was determined according to GOST 31986-2012, GOST ISO 11036-2017, GOST ISO 8588-2011. The optimal organoleptic combinations of the presented food acids and complex additives of sweeteners (CDP) were identified, which included aspartame, sodium saccharinate, Sucralose, sweetness coefficient – 340: the mixture with citric acid had a long pleasant aftertaste without foreign tastes and the best taste characteristics. Using the “A-not A” method, we found that the sample with the addition of CDP is identical to the sucrose solution. In the second part of the study, polysaccharides were added to model samples of acids with complex sweeteners; the best sensory characteristics were obtained by model samples consisting of a mixture of low-esterified Apple pectin with lactic acid and KDP. The technology of obtaining a stable elastic jelly using low-esterified Apple pectin has been developed, since the complex mixture of sweeteners and food acids does not have a dehydrating effect. Developed a dry mix recipe that can serve as a basic development, low-calorie sweet products for catering and has a variance of use of lactic and succinic acids, depending on the flavor characteristics of the raw materials used and its corrective ability.

Abstract Introduction Nephrolithiasis is pathological calcification in the excretory passages of the body and is prevalent among 7.6% of Indians. We aimed to study the various risk factors associated with renal stones from India. Method It was a hospital-based case-control study conducted over 18 months in a tertiary hospital in Delhi. Cases were defined as patients with renal stones diagnosed on the basis of history and radiological examination. Controls were similar to cases in all respects except for the diagnosis and selected from the hospital. A total of 18 risk factors, including age, gender, heavy metals, stress, metabolic factors, alcohol intake, dietary habits, co-morbidities, etc. were assessed. Logistic regression analysis was performed to calculate the strength of the risk associations. Results In the analysis of 60 cases and controls, we found 6 times, 5.5 times, and 2.4 times increased odds of renal stones in patients with increased arsenic, cadmium, and lead concentrations in blood, respectively. Similarly, there are 3 times increased odds of renal stones in patients suffering from stress. Conclusions Exposure to smoke, occupation dust, and contaminated water may lead to an increased ingestion/inhalation of heavy metals like cadmium, arsenic, and predisposing people to an increased risk of renal stones.

The presented study was aimed at the determination of the level of contamination with heavy metals (Cd, Pb, As, and Hg) in 240 samples of plant materials, i.e., herbal raw materials, spices, tea, and coffee. Moreover, a probabilistic risk assessment (noncarcinogenic and carcinogenic risks) was estimated by models including target hazard quotient (THQ) and cancer risk (CR). The samples were subjected to microwave mineralisation with the use of HNO3 (65%), while the determination of the content of the elements was performed with the use of inductively coupled plasma mass spectrometer (ICP–MS) and a mercury analyser. The element which was characterised by the highest level of accumulation in the analysed samples was lead (from 0.010 to 5.680 mg/kg). Among the heavy metals under analysis, the lowest concentration was noted in the case of mercury (from 0.005 to 0.030 mg/kg). A notably higher level of contamination with heavy metals was noted in the analysed samples of herbs and spices (0.005–5.680 mg/kg), compared to samples of tea and coffee (0.005–0.791 mg/kg). According to the guidelines of the World Health Organisation (WHO) concerning the limits of contamination of samples of herbal raw materials with heavy metals, lead levels exceeding the limits were only noted in 24 samples of herbs (18%). In all of the analysed samples of spices, tea, and coffee, no instances of exceeded limits were noted for any of the analysed heavy metals. The values of TTHQmax (in relation to the consumption of the analysed products) were as follows: up to 4.23 × 10−2 for spices, up to 2.51 × 10−1 for herbs, up to 4.03 × 10−2 for China tea, and up to 1.25 × 10−1 for roasted coffee beans. As the value of THQ ≤1, there is no probability of the appearance of undesirable effects related to the consumption of the analysed group of raw materials and products of plant origin. The CR value for As (max. value) was 1.29 × 10−5, which is lower than the maximum acceptable level of 1 × 10−4 suggested by United States Environmental Protection Agency (USEPA).
