    Research features of low-fat ice cream mixtures structuring with beta-glucan and pectin-containing vegetable raw materials
    (2022) Sapiga, Victoria; Mykhalevych, Artur; Osmak (Fedchenko), Tetiana; Polishchuk, Galyna
    Ice cream, as a food polydisperse system, requires special production conditions, in particular compliance with the maturation time of the ice cream mixtures, which ensures a regulated degree of the mixture structuring before freezing. Ice cream mixes show a viscosity anomaly, especially with a low shear gradient, so they are classified as non-Newtonian structured liquids. Effective viscosity is one of the most important y properties of non-Newtonian systems, which changes with the change in shear rate as a result of the gradual destruction of their structure.

    β-glucan as a Techno-Functional Ingredient in Dairy and Milk-Based Products — A review
    (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. Аналітичний огляд має наукове та практичне значення для науковців і спеціалістів у галузі виробництва харчових продуктів, зокрема молочних продуктів підвищеної харчової цінності.

    Improving the technology of restructured ham-type products from Turkey meat and PSE pork
    (2021) Shevchenko (Kishenko), Iryna; Polishchuk, Galyna; Topchiy, Oksana; Kotlyar, Eugene; Osmak (Fedchenko), Tetiana
    The research has proved the practical importance of using a biopolymer complex of thermostable animal proteins with functional and technological properties as a component of restructured ham-type products. It has been established that the water-holding and fat-holding capacity and the stabilising power of meat products significantly increase due to the introduction of the biopolymer complex developed by the authors, which contains sodium caseinate, buttermilk powder, and blood plasma Vepro 75 PSC. The experiments have confirmed that a protein-in- fat emulsion based on a biopolymer complex of thermostable animal proteins, a protein stabiliser obtained from turkey skin, and pork and turkey fats can be used as a component of restructured ham-type products from PSE pork and turkey meat.

    Analysis of the nature of the composition substances of sour-milk dessert with plant-based fillers
    (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

    Polyfunctional properties of oat β-glucan in the composition of milk-vegetable ice cream
    (2021) Sapiga, Victoria; Polishchuk, Galyna; Buniowska-Olejnik, Magdalena; Shevchenko (Kishenko), Iryna; Osmak (Fedchenko), Tetiana
    Ice cream is a structured multicomponent food product that is also an emulsion, foam and suspension. High-calorie ice cream with a fat content of at least 10–12% is stably in high demand due to its rich creamy taste, creamy consistency, and high resistance to melting. On the one hand, low-fat ice cream is of increasing interest to consumers as a new trend among low-calorie foods. On the other hand, the low content of fat (≤ 3%) and dry matter (≤ 30%) in ice cream has a negative effect on its quality.

    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.
