We analysed the raw materials in various food products, including additives, carrier solvents and end product for several selected organic pollutants. We analysed these food products for the type of chlorinated hydrocarbon pesticides, polychlorinated biphenyls and other currently used pesticides.We analysed three product categories: bakery products, canned mushroom and meat products. The analysis of the bakery products and of the canned mushroom did not conclude in positive findings, which means that these products contained the agents given during the production of the product and the environmental pollutants in undetectable low concentration.However, the results for meat and fish products indicate that polychlorinated compounds are persistent and are of a lipophyl character, as some of these components have been detected in these food products, the concentration of the PCBs were detected in the range of 9.8-24 μg/kg.

Consumer demand for both plant products and meat products enriched with plant raw materials is constantly increasing. Therefore, new versatile and reliable methods are needed to find and combat fraudulent practices in processed foods. The objective of this study was to identify oilseed species-specific peptide markers and meat-specific markers that were resistant to processing, for multispecies authentication of different meat and vegan food products using the proteomic LC-MS/MS method. To assess the limit of detection (LOD) for hemp proteins, cooked meatballs consisting of three meat species and hemp cake at a final concentration of up to 7.4% were examined. Hemp addition at a low concentration of below 1% was detected. The LOD for edestin subunits and albumin was 0.9% (w/w), whereas for 7S vicilin-like protein it was 4.2% (w/w). Specific heat-stable peptides unique to hemp seeds, flaxseed, nigella, pumpkin, sesame, and sunflower seeds, as well as guinea fowl, rabbit, pork, and chicken meat, were detected in different meat and vegan foods. Most of the oilseed-specific peptides were identified as processing-resistant markers belonging to 11S globulin subunits, namely conlinin, edestin, helianthinin, pumpkin vicilin-like or late embryogenesis proteins, and sesame legumin-like as well as 2S albumins and oleosin isoforms or selected enzymic proteins.

The article discusses the issue of assessing the safety of food products that are traditional for the Ukrainian consumer (bakery products and wheat flakes). The relevance of the work is due to the fact that safety is an important indicator of consumer properties that all food products should have. The biological methods are widely used, including biosensor technologies and biotestingto assess the safety of food products. Biotesting is one of the research methods used to determine the degree of influence of chemicals potentially hazardous to living organisms by registering changes in biologically significant indicators (test functions) of research test objects with subsequent assessment of their condition in accordance with the selected toxicity criterion. The work assessesthe organoleptic indicators of the test samples. As a result, it was established that the samples fully comply with the requirements of the regulatory documentation, except for sample № 7 in which dampness and an off-taste are felt; this may indicate non-compliance with the storage or sale conditions. The safety of bakery products and wheat flakes was assessed using the Colpoda Steinii ciliate test object. It was established that the test samples did not contain toxic substances, and in the sample № 7 – wheat flakes purchased by weight on the market, the death of most of the Colpoda Steinii occurred within 10 minutes. This indicates its insignificant toxicity and the inadmissibility of further sale of such a product to the population. The second method was used to test the lethality of Daphnia Magna Straus (Crustacea).The results showed that in samples № 1 – 6 the number of dead Daphnia corresponds to the "non-toxic" indicator, but in sample No. 7 the number of dead Daphnia was 25%, which indicates the toxicity of this product. The third method was carried out according to the method based on the non-destructive biocrystallization method. It was established that samples 1 and 2 are characterized by the most symmetric biocrystallogram, which indicates their higher degree of organicity, which, in our opinion, is determined by a smaller share of external negative impact on the product and high-quality raw materials that were used in the production of these samples.

One of the ways to address the food quality issues facing the industry is the development of standardized and certified methods related to the conduct of in-depth studies of biochemical indicators of quality and safety of meat and meat products. The world laboratory practice in the field of food quality and safety shows a constant expansion of the list of controlled indicators of food raw materials and products. An important feature of the modern period in the development of biomedical and biotechnological research is the introduction of a whole complex of postgenomic technologies, which are based on a systematic approach to the study of the functioning of the mammalian proteome in various physiological and pathological conditions, including the formation and development of alimentary-dependent pathologies. In this regard, the problem of multilateral study of food products, in particular their identification, is the most relevant, because the modern technology of their production has undergone significant changes and requires the development of “gentle “ processing modes. They concern raw materials and auxiliary materials used at all stages of production. This and new technologies of production of protein products from plant raw materials, as well as the introduction of food raw materials and food additives of artificial origin and the excess introduction of additives of plant and animal origin can cause falsification of products, as well as affect the health of the consumer. Food quality assessment includes the control of components of finished products. It is most difficult to determine the proportion of muscle protein in multi-component meat products that have undergone heat treatment. Therefore, in practice, when assessing the quality of food products, there is a need to identify its real composition in accordance with the declared normative documents. Currently, a promising area of research in the field of determining the composition of finished food is the selection of biomarkers of various components. Therefore, it is important to develop a methodology for the identification of biochemical changes in food raw materials under the influence of technological factors using modern research methods. This paper provides an overview of the protein and peptide analysis methodology, including the latest technologies that are becoming increasingly important.

Solving the current problems of improving the quality and safety of food fish products is possible only if modern and objective methods of analysis are used. Ensuring the proper quality and safety of wild fish products produced by enterprises is possible through compliance with interstate and national standards and regulatory documents. Currently operating GOST 30812 "Raw materials and food products. The method of identifying sturgeon fish caviar "based on the establishment of morphological features of sturgeon fish caviar is the result of research work carried out by the Kasprybtestcenter and the Russian Academy of Sciences for the period 1997-1998. The morphological features of sturgeon fish caviar specified in the standard depend on various factors, and do not allow to establish belonging to the species. Morphological signs of caviar (grain size, cytogenetic structure) are changing indicators that depend on many factors that affect the physiological state of fish during cultivation. Modern studies conducted by the standardization and rationing group of the Volga-Caspian branch of Russian Federal Research Institute of Fisheries and oceanocraphy together with the laboratory of molecular genetics of Russian Federal Research Institute of Fisheries and oceanocraphy indicate that the more reliable way to identify caviar is to establish molecular genetic features. Genetic features are a stable criterion that reflects the hereditary material of parents. Developed an updated standard "Fish food products. Method for identifying the caviar of fishes of the sturgeon family. " The development of identification methods is based on the use of a complex of visually detectable signs of the macro and microscopic structure of the eggs of sturgeon and paddle-bearing fish species and the molecular genetic method Updated standard "Raw materials and food products. The method of identification of sturgeon fish caviar", supplemented by the modern molecular genetic method of identification of sturgeon fish and oatmeal, will provide a regulatory and technical basis for the functioning of the traceability system from the place of obtaining raw caviar to the store counter, which will significantly reduce the share of illegal, counterfeit and falsified products the functioning of the traceability system from the place of receipt of raw caviar to the store counter, which will significantly reduce the share of illegal, counterfeit and counterfeit products.

Against the background of adverse environmental conditions in Ukraine, experts in the field of medicine, food hygiene note the raising importance of various nutritional factors in increasing the risk of developing cancer. A number of compounds resulting from protein denaturation during the heat treatment of meat and fish products can pose a high risk. Such compounds include heterocyclic aromatic amines (HAA) i.e. substances that, in extremely low concentrations, can carry out mutagenic and carcinogenic effects on the human body. Aim of the Research. To analyse studies from available sources of information about the likelihood and conditions of the formation of chemicals hazardous to human health in foods of animal origin during thermal cooking. Methods and Materials. Review and analysis of scientific publications based on the results of experimental studies of European, American and Japanese scientists. Results and Discussion. Studies have established that in the process of thermal cooking of food products of animal meat, poultry, fish, HAA are formed and accumulate as a result of complex multi-stage chemical reactions with the obligatory participation of amino acids, sugars, creatine and creatinine, which is its cyclic form. The formation of mutagenic HAA is affected by a number of conditions. For example, the accumulation of heterocyclic aromatic amines in fried meat products is most affected by the temperature of the surface of the pan and the outer layer of meat, the duration of frying, the degree of meat chopping, the presence of breading, pickling, the addition of onions to the chopped meat. Conclusions. Taking into account that the diet of more than 40% of the population includes products containing HAA, the development and justification of safety criteria for meat and fish products concerning the content of heterocyclic aromatic amines as well as the development of ways to prevent their formation form an urgent problem. The following tasks must be solved as priorities: – to develop and standardize methods for the determination of HAA in various types of food products; – to conduct studies of the content of HAA in meat and fish products and in culinary products; – to study the influence of various methods of thermal cooking on the accumulation of HAA in finished products made from meat and fish; – to study the effect of the raw materials used and production technologies on the accumulation of HAA in food products; – to optimize the formulae of meat and fish products and their production technologies in order to minimize the number of HAA formed in the finished product; – to justify the acceptable levels of HAA in food products and to develop safety criteria for meat and fish products concerning the content of HAA on the basis of clinical and laboratory studies. Key Words: heterocyclic aromatic amines (HAA), meat products, fish products, thermal cooking, safety.
