(2022) Polishchuk, Galyna; Bandura (Kuzmyk), Uliana; Osmak (Fedchenko), Tetiana; Kurmach, Mykhailo; Bass, Oksana
The nature and interaction of the constituent substances that make up the sour-milk dessert with plant-based fillers have been studied by the method of IR spectroscopy. This method is used to study the diverse nature of substances. The spectral range applied was in the range of 500–4,000 s -1. It was found that the intensity of functional groups absorption in the range of 2,500–3,500 s-1 is due to the valence vibrations of NH-, CH and S-H-groups, indicating the presence of free organic acids, aromatic substances. In addition, in the spectra of sour-milk dessert with plant-based fillers, an absorption intensity in the range of 1,470–1,335 s-1 is observed, which indicates the presence of soluble pectin. Proteins characteristics in the samples are observed at absorption in the range of 3,300–3,500 cm-1, which is due to the valence vibrations of the N-H bond in the -NH2 groups

(2022) Mykhalevych, Artur; Kostenko, Olena; Polishchuk, Galyna; Bandura (Kuzmyk), Uliana
The rational doses of milk-protein ingredients in reduced fat sour cream that prevent excessive acidity of milk cream during fermentation, structure and stabilize this product during 5 days of storage, are the following: skimmed milk powder, 1%, sodium caseinate, 0.5%, caseinate calcium, 0.75%, whey protein concentrate, 1%, hydrolyzed whey concentrate, 30%. According to the level of inhibition of the lactic acid fermentation, milk-protein concentrates in the specified quantities can be arranged in the following sequence: skimmed milk powder → whey protein concentrate → caseinate calcium → hydrolyzed whey concentrate → sodium caseinate. By microstructural analysis of reduced fat sour cream, it was determined that 1% whey protein concentrate ensures proper moisture binding in the sour milk clot and contributes to the formation of a delicate structure with finely dispersed cells, while the use of 30% hydrolyzed whey concentrate forms a more viscous consistency of the product due to the presence of monosaccharides in it, which have a higher adsorption capacity for free moisture. The greatest structuring ability of caseinates and the most significant influence of whey proteins on the thixotropic properties of the reduced fat sour cream have been proved. A comprehensive indicator of the quality of reduced fat sour cream with milk-protein concentrates was calculated. Samples with 1% whey protein concentrate and 30% hydrolyzed whey concentrate had the most attractive sensory indicators, and got the highest score. The chemical composition of reduced fat sour cream samples with whey proteins was studied. It was found that 1% of whey protein concentrate increases the biological value by 1.3%, while 30% of hydrolyzed whey concentrate decreases it by 3.5%. According to the research results, whey protein concentrate was classified as a biological enhancer with moderate technological properties, and hydrolyzed whey concentrate as an effective technological additive that imitates the quality indicators of an analogue with medium fat content of 18-20%. Раціональними дозами молочно-білкових інгредієнтів у складі низькожирної сметани, що запобігають перекисанню вершків, структурують та стабілізують цей продукт впродовж 5-ти діб зберігання є наступні: сухе знежирене молоко – 1%, казеїнат натрію– 0,5%, казеїнат кальцію – 0,75%, концентрат сироваткових білків – 1%, концентрат гідролізованої сироватки – 30%. За ступенем гальмування процесу молочнокислого бродіння молочно-білкові концентрати у вказаних кількостях можна розташувати у такій послідовності: сухе знежирене молоко → концентрат сироваткових білків → казеїнат кальцію → концентрат гідролізованої сироватки → казеїнат натрію. За результатами мікроструктурного аналізу зразків низькожирної сметани визначено, що 1% концентрат сироваткових білків забезпечує належне утримання вологи у кисломолочному згустку та сприяє формуванню ніжної структури з дрібнодисперсними комірками, а використання 30% концентрат гідролізованої сироватки формує більш в’язку консистенцію продукту за наявності в ньому моноцукрів, які мають вищу адсорбувальну здатність вільної вологи. Доведено найбільшу структуруючу здатність казеїнатів та найсуттєвіший вплив сироваткових білків на тиксотропні властивості сметанного продукту. Проведено органолептичну оцінку та розраховано комплексний показник якості зразків низькожирної сметани та визначено зразки з 1% концентрат сироваткових білків та 30% концентратом гідролізованої сироватки як такі, що мають найбільш привабливі органолептичні показники. Досліджено хімічний склад зразків низькожирної сметани з сироватковими білками. Встановлено, що 1% концентрат сироваткових білків підвищує біологічну цінність на 1,3%, в той час як 30% концентрат гідролізованої сироватки знижує на 3,5%. За результатами досліджень, концентрат сироваткових білків було віднесено до біологічного збагачувача з помірними технологічними властивостями, а концентрат гідролізованої сироватки до ефективної технологічної добавки, що імітує показники якості аналогу із середньою жирністю 20%.

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

The modern range of milk-based ice cream with an alcohol component was analyzed. The choice of alcoholic tincture in the composition of milk ice cream was substantiated. The cryoscopic temperature of the mixtures was determined using a measuring complex, the dynamic viscosity was determined by a Heppler viscometer, the melting resistance was determined by the melting time of the hardened ice cream samples, and the ice cream was whipped by the weight method. The possibility of using tinctures with an alcohol content of 20% as a part of milk ice cream has been scientifically confirmed. The selection of the structure stabilizer and rational modes of maturation of milk-alcohol mixtures were substantiated by the values of the coefficient of dynamic viscosity. According to the cryoscopic temperature of ice cream mixtures, it was found that the production of ice cream with a mass fraction of alcohol up to 3% determines the possibility of using conventional freezing modes to obtain a product of guaranteed quality. A new type of milk ice cream with the use of tinctures can be recommended for the introduction of the classical technological scheme of production with the clarification of maturation modes.

(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.

(2021) Mykhalevych, Artur; Osmak (Fedchenko), Tetiana; Polishchuk, Galyna; Bandura (Kuzmyk), Uliana
Ice cream belongs to the group of dairy desserts that are in great demand among consumers and have a high nutritional value. The modern range of ice cream is quite wide, but unfortunately, almost does not include ice cream with a balanced content of essential nutrients. Instead, the range of domestic ice cream is mainly high-fat products of cream and ice cream groups, although the world's demand for low-calorie milk ice cream is growing every year. To improve the nutritional status of the population of Ukraine, a new type of acidophilic enriched ice cream has been developed at the Department of Milk and Dairy Products Technology of NUFT. Ice cream was produced on the basis of whey with the use of a complex of proteins (whey protein concentrate, sodium caseinate, soy protein isolate) and probiotic starter based on Lactobacillus acidophilus. To improve consumer characteristics, vegetable pectin-containing paste was introduced into fermented milk ice cream.
