Карвон є ключовим компонентом ефірних олій рослин Anethum graveolens L. (кріп) і Mentha spicata L. (м'ята). Встановлено, що ефірні олії містять карвон у різних оптично активних формах. Ефірна олія кропу містить d (R) – карвон (правоповоротна ізомерна форма) зі специфічним обертанням площини поляризації [α] D + 62,5 +0,05; ефірна олія м’яти Mentha spicata містить l(S) –карвон (лівообертаюча ізомерна форма) зі специфічним обертанням площини поляризації [α] D – 63,2 +0,05. Порівнюючи дію оптичних ізомерів карвону між собою за динамікою окиснення жировмісних продуктів, встановлено, що в цілому їх захисна дія подібна. Однак лівий карвон демонструє більший вплив на стійкість соняшникової олії порівняно з правим карвоном. Крім захисту від окислення, оптичні ізомери карвону можуть надавати фізіологічну дію на організм людини. Таким чином, оптичні ізомери карвону можуть надавати певні аромати харчовим продуктам, а при створенні функціональних жировмісних продуктів можливе використання обох оптичних форм карвону в залежності від спрямованості нового функціонального продукту.

Determining the efficiency of using egg products for the stabilization of emulsion when making milk-containing curdsbased products
(2020) Belemets, Tatiana; Radzievska, Irina; Yushchenko (Gonchar), Natalia; Bandura (Kuzmyk), Uliana
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

(2021) Belemets, Tatiana; Radzievska, Irina; Tochkova, Oksana; Yushchenko (Gonchar), Natalia; Bandura (Kuzmyk), Uliana; Mykhalevych, Artur
It is known that one of the main causes of spoilage of fats (in particular vegetable fats), as well as products made with their use, is an increase in acid and peroxide numbers. Physicochemical indicators have a significant impact not only on the quality and organoleptic characteristics of the product, but also on its safety. For this purpose, the dependence of the indicators of acid and peroxide numbers of the created blend of vegetable oils in the technologies of milk-containing products during storage has been investigated. The object of research is experimental samples of a three-component blend of vegetable oils and milk fat isolated from milk-containing curd paste and milk-containing sour cream sauce. The subject of research is the dynamics of the growth of acid and peroxide numbers of samples and changes in their organoleptic quality indicators. The obtained data on the kinetics of oxidation of a blend of vegetable oils indicate that the increase in acid and peroxide numbers during the studied shelf life does not differ in intensity. The average threshold for an increase in acid and peroxide numbers is insignificant and amounts to 0.02–0.03 mgKOH/h and 0.2–0.21 mmol1/2O/kg for 5 days. In accordance with the obtained results of the kinetics of oxidation of the released fat of milk-containing curd paste, there is a slight increase in acid and peroxide numbers, namely: at the end of 7 days – up to 0.3 mgKOH/h and 1.9 mmol1/2O/kg, respectively, and in at the end of 10 days– up to 0.32 mgKOH/h and 2.3 mmol1/2O/kg. Based on the obtained results of the kinetics of oxidation of the released fat from the milk-containing sour cream sauce, there is a tendency to a gradual increase in the acid and peroxide numbers with an increase in the oxidation time. It is noted that the maximum values of acidic – 0.3 mgKOH/h and peroxide numbers – 2.2 mmol1/2O/kg at the end of the shelf life of 21 days are reached. According to the results obtained for the organoleptic evaluation of experimental samples of the blend and the released fat from milk-containing products, no significant changes were found during the studied shelf life.
