The method of solution of the problem of polyunsaturated fatty acids (PUFA) lack in milk products is offered in the work. It is offered to create the milk-containing products (sour cream product) with adjusted fatty acid composition. The possibility of replacement of the mass part of milk fat (50 %) by the blend of natural vegetable oils was studied. For the solution of this problem the program within MatLab mathematical package was elaborated. The recommended fatty acids (FA) ratio [3] is selected as optimization parameter. The optimized blend was created using the elaborated program. The data, received by mathematical calculations, were experimentally proved using the method of gas-liquid chromatography [7]. On the based of the results, received at the studies, it can be stated, that 50 % replacement of mass part of fat (m.p.f.) in milk products (sour cream product) by elaborated blend, allows partially adjust its FA composition.

supplier of physiologically functional ingredients. That is why daily consumption of the required amount of fat is important for normal functioning of every human organism [1, 2]. On the basis of medical and biological research, fatty acids should get to the human body on a daily basis in accordance with the norms established by nutritionists: 80...150 g/day for men and 65...100 g/day for women. And fats of vegetable origin (oils) should contain 30 % of the total amount of consumed fat. Studies conducted at the level of a whole organism and at the cellular and molecular levels demonstrated that physiological effectiveness of food fats depends not only on the existence in them of polyunsaturated fatty acids (PUFA) but also on the optimum ratio between all three groups of fatty acids. Triacylglycerols in food products should contain 10...20 % of polyunsaturated fatty acids (PUFA), 50…60 % of monounsaturated fatty acids (MUFA) and 30 % of saturated fatty acids (SFA). Among PUFA, the ratio of ω-6:ω-3 groups should make from 4:1 to 10:1. The

The appropriateness of using the phospholipids of egg products has been considered as an alternative to synthetic emulsifiers in the technology of making milk-containing curds-based sour milk products (hereinafter, milk-containing products) of the functional purpose. Underlying the development is the improvement of conventional technology by replacing 50 % of milk fat with a blend of natural vegetable oils (based on the mathematically calculated ratios). This could increase the content of essential fatty acids to the level commensurate with the physiological norms of their consumption. Adding the products of chicken egg processing as a useful and safe natural emulsifier would prevent the separation of the product's fatty phases. The emulsifying mixture "Prottekt 01" has been used as control. The rational dosage for introducing the selected natural emulsifiers has been determined, based on the calculation of 1...4 % to the mass of the introduced vegetable fats (blend), which ensure the highest fat-retaining capacity (FRC) indicator and do not affect the organoleptic characteristics of the product. It has been established that the stability of direct emulsifiers (DE) «o/w» is 100 % in the case of using egg yolk powder or the emulsifier "Prottekt 01" in the amount of 3 %; egg powder or albumin-4 %. The rational ratio of the formulation components has been determined for such emulsions-water phase:vegetable oil blend:egg yolk powder-as 21:76:3, provided the lowest possible percentage of a water phase (whey) is introduced. The dependence of a moisture-retaining capacity indicator on the moisture content in a milk-containing product that included the experimental samples of emulsions has been confirmed. The dependence established is in good agreement with a phenomenon of the reduced moisture-retaining capacity in a food product when its fat content increases as a result of the lower moisture-retaining capacity of the fatty phase compared with the protein phase. The derived dependence of lecithin content on the indicators of FRC and DE proves the appropriateness of choosing the egg yolk powder as an emulsifier for making a milk-containing curds-based sour milk product. The highest indicators of FRC, 5 cm3/g, and the formation of 100 % of DE, are observed when using 3 % of the egg yolk powder (with a lecithin content of 10.3 g/100 g of the product) in the emulsifier composition

The work is devoted to optimization modeling of an influence of pasteurization with oxygen absorbers on spoilage processes of lipids of boiled sausage products. According to the results, the influence on changes of peroxide and acid numbers of lipids of small sausages, pasteurized at presence of an oxygen absorber, has been mathematically prognosticated. At mathematical modeling, mathematic packages MathCad and «Data analysis» (ЕТ) MSExcel were used. The experiment was planned according to the plan of full factorial experiment. The dependence as to the influence of the recipe composition of sausage products at their storage on peroxide and acid number values has been revealed. The conducted modeling allows to state the adequacy of obtained regressive equations. The obtained empirical dependencies allow to prognosticate a storage term of boiled sausages products, pasteurized with elements of active package at using protecting barrier multi-layer polymeric materials. The optimization modeling was conducted by structuring a mathematical model as an analytic expression that reflects the connection of factor signs with a parametric index. The obtained response functions are adequate and have a high correspondence to real experimental data. Storage terms were substantiated for small sausages, which recipe included beef, pork, poultry meat and also food emulsions, based on animal proteins. The process of repeated pasteurization was conducted at temperature 85–90 °С during 15–20 minutes
