(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

The scientific and practical interest in the dairy industry is the development aimed at obtaining food with high nutritional value, which corresponds to the basic concept of balanced and rational nutrition. These products include the technology of frozen desserts (ice cream) using milk -protein concentrates. At the Department of Technology of Milk and Dairy Products of the National University of Food Technologies (Kyiv, Ukraine), ice cream formulations were developed, which include full -fledged protein concentrates - cottage cheese and soy protein concentrate.
Cryoprotective ability of starch syrup in the composition of aromatic and fruit-berry ice cream
(2019) Polishchuk, Galyna; Bass, Oksana; Osmak (Fedchenko), Tetiana; Breus, Natalia
For complete replacement of sugar in the ice cream the starch syrup of different degree of saccharinization was chosen: glucose-fructose syrup GFS (dextrose equivalent 98) and syrup caramel SC (dextrose equivalent 30). GFS, in comparison with control samples with sugar, due to the high content of mono-sugars, significantly reduces the cryoscopic temperature of the mixtures. While, the SC boosts this figure. Therefore, in order to maintain the recommended balance on the content of frozen water at each stage of low-temperature processing of ice cream mixtures, it is expedient to combine the cryoprotective capacity of the syrup with different dextrose equivalent. The ranges of optimal correlations between GFS and SC in compositions were calculated, allowing to receive the content of frozen water, according to control samples – from 30:70 to 40:60 for aromatic ice cream and from 50:50 to 90:10 – for fruit-berry ice-cream. Microstructural analysis of ice cream samples has demonstrated the expediency of complete replacement of sugar on the syrup compositions, which provides the formation of a more homogeneous finished product structure, compared with control samples with sugar.Для повної заміни цукру в морозиві було обрано крохмальний сироп різного ступеня сахаринізації: глюкозо-фруктозний сироп GFS (декстрозний еквівалент 98) та сироп карамельний SC (декстрозний еквівалент 30). GFS, порівняно з контрольними зразками з цукром, завдяки високому вмісту моно-цукрів значно знижує кріоскопічну температуру сумішей. У той час як НС збільшує цю цифру. Тому, щоб підтримувати рекомендований баланс за вмістом замерзлої води на кожному етапі низькотемпературної обробки сумішей з морозивом, доцільно поєднувати кріопротекторну здатність сиропу з різним еквівалентом декстрози. Діапазони оптимальних співвідношень між GFS та SC у композиціях розраховувались, що дозволяло отримувати вміст замороженої води, за контрольними зразками - від 30:70 до 40:60 для ароматичного морозива та від 50:50 до 90:10 - для фруктово-ягідного морозива. Мікроструктурний аналіз зразків морозива продемонстрував доцільність повної заміни цукру на сиропних композиціях, що забезпечує формування більш однорідної структури готового продукту порівняно з контрольними зразками з цукром.

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) 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.
Food value study of acidophilic-whey ice cream
(2021) Polishchuk, Galyna; Osmak (Fedchenko), Tetiana; Bass, Oksana; Mykhalevych, Artur
The dietary structure of most people is extremely inconsistent with modern principles of rational nutrition and practical dietetics. By developing and improving the composition of products that increase the body's resistance in an unfavorable environment, including dairy, it is quite possible to improve the quality of human life, as well as to ensure the body's adaptation to unfavorable living and working conditions. Based on the results of previous studies, new types of acidophilic-whey ice cream, enriched with protein, have been developed. The amino acid composition and mineral composition of new types of ice cream enriched with protein were investigated with the help of amino acid and express analyzers. Based on the daily human need for these substances, it was concluded that the biological value of ice cream, enriched with a complex of proteins, increased by 15% in comparison with the control. It was also found that the introduction of pectin-containing raw materials into the composition of acidophilic-whey ice cream with protein concentrate provides a ratio of minerals that is close to the optimal for all age categories.
