(2022) Mykhalevych, Artur; Polishchuk, Galyna; Nassar, Khaled; Osmak (Fedchenko), Tetiana; Buniowska-Olejnik, Magdalena
The article systematizes information about the sources of -glucan, its technological functions and practical aspects of its use in dairy and milk-based products. According to the analysis of scientific information, the main characteristics of -glucan classifications were considered: the source of origin, chemical structure, and methods of obtention. It has been established that the most popular in the food technology of dairy products are -glucans from oat and barley cereal, which exhibit pronounced technological functions in the composition of dairy products (gel formation, high moisture-binding capacity, increased yield of finished products, formation of texture, and original sensory indicators). The expediency of using -glucan from yeast and mushrooms as a source of biologically active substances that ensure the functional orientation of the finished product has been revealed. For the first time, information on the use of -glucan of various origins in the most common groups of dairy and milk-based products has been systematized. The analytical review has scientific and practical significance for scientists and specialists in the field of food production, in particular dairy products of increased nutritional value. У статті систематизовано відомості про джерела отримання β-глюкану, його технологічні функції та практичні аспекти використання в молочних і молоковмісних продуктах. За результатами аналізу наукової інформації розглянуто основні характеристики класифікацій β-глюканів: за джерелом походження, хімічною будовою та способами отримання. Встановлено, що найбільш популярними в харчовій технології молочних продуктів є β-глюкани вівса та ячменю, які виявляють виражені технологічні функції у складі молочних продуктів (гелеутворення, висока вологозв'язуюча здатність, підвищення виходу готової продукції, формування текстури та оригінальні сенсорні показники). Обґрунтовано доцільність використання β-глюкану з дріжджів та грибів як джерела біологічно активних речовин, що забезпечують функціональну спрямованість готового продукту. Вперше систематизовано відомості про використання β-глюкану різного походження в найбільш поширених групах молочних і молоковмісних продуктах.

Development of a new type of alcoholic ice cream
(2021) Kochubei-Lytvynenko, Oksana; Polishchuk, Galyna; Osmak (Fedchenko), Tetiana; Bass, Oksana; Mykhalevych, Artur; Bandura (Kuzmyk), Uliana
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) Sapiga, Victoria; Mykhalevych, Artur; Osmak (Fedchenko), Tetiana; Polishchuk, Galyna
In foods, especially structured, an important role is played by the use of stabilizing substances, which include pectins. As protective colloids, they perform important technological functions - have a stabilizing and emulsifying ability, form a creamy consistency and increase overrun, which is important for the formation of ice cream quality indicators.
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.
Scientific explanation of composition of acidophilic-whey ice cream, enriched with protein

Study of vegetable raw materials influence on cryoscopic temperature and the content of free and bound moisture in milk-vegetable blends
(2019) Sapigа, Victoria; Mykhalevych, Artur; Polishchuk, Galyna; Osmak (Fedchenko), Tetiana
In recent years in Ukraine, a group of structured dairy based dessert products (ice cream, mousse, creams, sambukes, etc.) are particularly popular among consumers . Such food systems require the obligatory content of stabilizers and stabilization systems: starches, gums, pectins, proteins, sulfated polysaccharides, their composite mixtures and integrated complexes with emulsifiers. This results, on the one hand, in increasing the cost price of the finished product, since most of these nutritional supplements do not produce domestic enterprises, and on the other hand, such compounds and their mixtures, mostly chemically modified and synthesized, not only do not affect the nutritional value of finished products, but also have some restrictions for the application. Therefore, a promising trend is to expand the range of ice cream on the basis of natural functional and technological raw materials of vegetable origin, in particular vegetable.

(2019) Sapigа, Victoria; Polishchuk, Galyna; Osmak (Fedchenko), Tetiana; Mykhalevych, Artur; Maslikov, Maxim
The modern assortment of ice cream on milk base with vegetable fillers has been analyzed. The choice of vegetable raw material as a promising functional and technological ingredient in composition of milk ice cream is substantiated.Object ofresearch - ice cream technology. The subject of the study - vegetable puree from beet and broccoli fresh and heat-treated, ice cream and milkvegetable blends. The cryoscopic temperature of the blends was determined with the aid of a measuring complex,dynamic viscosity by Geppler viscometer, resistance to melting - the melting time of hardened ice cream samples, the air bubbles size - the microscopy of soft ice cream samples in the chamber Goryaev, ice cream overrun - by the weight method.Object ofresearch - ice cream technology.

The possibility of partial replacement of the stabilizer of the structure on pectin containing puree is established, which, in addition to the structural function, acts as a natural dye and a taste-aromatic ingredient, enriches the product with a complex of carbohydrates and minerals. By the magnitude of dynamic viscosity coefficient, rational regimes of maturating milkvegetable blends with different ratios between the milk and vegetable component were substantiated. It has been established that functional and technological vegetable puree in the amount of 10-20% practically does not affect the сryoscopic temperature of ice cream blends, which makes it possible to apply commonly accepted freeze modes to obtain a product of guaranteed quality.
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.

(2018) Grek, Olena; Osmak (Fedchenko), Tetiana; Chubenko, Larysa; Mykhalevych, Artur
The emergency of the development of new frozen desserts with protein-milk concentrates, obtained by different coagulation methods, is substantiated. The advantages of using the thermo & heat coagulation of milk proteins are taken into consideration. Having in view the complex influence on the proteins of high temperature milk and the Rumex acid reagent, the parameters of the process are specified. As raw material for coagulation, skimmed milk with a mass fraction of dry matter of 11.2 ± 0.7%, protein, 3.7 ± 0.2%, titrated acidity, 17 ± 1.0°T, density, 1032 kg/m3 was selected. The amount of coagulant with a pH of 3.1 at a level of'7± 0.5% of the weight of skimmed milk satisfies the requirements for protein-herbal clots according to quality indices.
