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

(2016) Yushchenko (Gonchar), Natalia; Radzievska, Irina; Belemets, Tatiana
Cultured milk foods should be consumed daily, because they include due to high food and biological value. Admittedly, milk fat contains 60...65% SFA, in the proportion of SFA to UFA are about — 0.5, in contrast to the «ideal fat» — 0.7...0.8. Therefore, the development of components for enriching fat cultured milk foods, as a source of unsaturated fatty acids, is the actual task of researches.

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.

Натуральні рослинні олії (кукурудзяна, рапсова та олія волоського горіху) були обрані для створення купажу з оптимізованим жирнокислотним складом на їх основі. Даний вибір олій є обґрунтованим відповідно до їх фізико-хімічних характеристик, жирнокислотного складу, сумісністю з молочною основою, біологічної цінності та органолептичними показниками. Розроблений купаж натуральних рослинних олій повинен бути використаний для поєднання з молочними продуктами масового вжитку з метою оптимізації їх жирнокислотного складу. The natural vegetable oils (corn, rapeseed and walnut oils) were selected to create the blend, optimized by the fat and acid composition on their basis. This choice of oils is substantiated according to their physical and chemical characteristics, the fat and acid composition, and compatibility with the milk base, availability, and organoleptic parameters. The developed blend of natural vegetable oils should be combined with dairy products of mass consumption for the optimization of their fat and acid composition.

(2020) Belemets, Tatiana; Radzievskaya, Irina; Yushchenko (Gonchar), Natalia ; Kuzmyk, Uliana
Актуальним є збагачення борошняних виробів рослинними джерелами магнію. Одним з таких рослин є шпинат городній – однорічна рослина, представник роду Spinacia. З цією метою вивчено функціонально-технологічні властивості цільнозернового борошна для обґрунтування його використання у технології чапаті. Результати досліджень показали, що найбільшу водопоглинальну здатність має ячмінне борошно – 400 %, у рисового та пшеничного цей показник майже вдвічі менший. Найбільшою жироутримувальною здатністю володіло ячмінне борошно – 87%, тоді як у контролі (борошно пшеничне вищого сорту) цей показник становив 25 %. Визначено технологічні параметри приготування шпинату у складі чапаті: розмір частинок – 250 до мкм; оптимальна кількість внесення цільнозернового борошна до маси – 3 %; тривалість процесу набухання після замісу тіста – 15–20 хв для створення загальної просторової структури. Розрахунок енергетичної цінності свідчить про те, що калорійність чапаті є несуттєвою в порівнянні з основними стравами і становить в середньому 220,0 ккал/100 г. Таким чином, використання шпинату разом із цільнозерновим борошном у чапаті дає можливість підвищити ступінь забезпечення добової потреби організму людини в основних харчових речовинах.
