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.
Development of mathematical apparatus of the expert system for modelling ice cream recipes with specified quality parameters
(2019) Breus, Natalia; Hrybkov, Serhii; Polishchuk, Galyna; Seidykh, Olga
As a result of the development of the expert system mathematical apparatus, a set-theoretical mathematical model of the finished product quality control at the stage of operative planning of new types of ice cream with increased nutritional value has been obtained; multi-component ice cream recipes have been optimized in terms of composition; and a model for determining the optimal set of control actions in the presence of technological defects in the calculation of recipes has been built.
Enzymatic destruction of protopectin in vegetable raw materials to increase its structuring ability in ice cream
(2021) Sapiga, Victoria; Polishchuk, Galyna; Breus, Natalia; Osmak (Fedchenko), Tetiana
The expediency of protopectin enzymatic hydrolysis of vegetable raw materials as a functional-technological semi-finished product for ice cream production is proved. In dispersed food systems, pectins as protective colloids have a stabilizing and emulsifying ability, form a creamy consistency, increase whipping and control syneresis, which is important for the formation of ice cream quality indicators. Highly purified pectin preparations are usually used in ice cream.

(2017) Breus, Natalia; Hrybkov, Serhii; Polishchuk, Galyna
The method of ice cream recipe modeling is developed, which, unlike traditional ones, is based on the application of processing expert data and optimization methods. It allows to significantly expand the range of tasks. These tasks solutions can bring significant economic effect.
Studies of water freezing features in ice cream with starch syrop
(2019) Polishchuk, Galyna; Sharahmatova, Tetiana; Breus, Natalia; Bass, Oksana; Shevchenko (Kishenko), Iryna
The purpose of the study is to research the process of water freezing in new types of ice cream with starch syrup at certain stages of the technological process. Starch syrup as a degradation product of corn starch is characterized by different values of the dextrose equivalent (DE). Starch syrup is a source of solids, sweetener, cryoprotectants (at high DE) and thickener (for low values of DE). The starch syrups with fundamentally different functional and technological properties are chosen for the study: high glucose-fructose syrup HGFS-98 (DE = 98) and low-sugar starch syrup GFS-30 (DE = 30).
Study of the influence of micellar casein and spelt flour on yoghurt quality indicators
(Study of the influence of micellar casein and spelt flour on yoghurt quality indicators / G. Polischuk, N. Breus, O. Kochubey-Litvinenko, Т. Osmak, T. Semko, M. Borova // EUREKA: Life Sciences. – 2020. – № 4. – P. 44-52., 2020) Polishchuk, Galyna; Breus, Natalia; Kochubei-Lytvynenko, Oksana; Osmak (Fedchenko), Tetiana; Semko, Tetiana; Borova, Marina
The aim of the research is to study the effect of protein-containing ingredients of animal and plant origin on the quality indicators of yoghurt for the scientific substantiation of its recipe composition. Micellar casein and spelled flour are characterized by high nutritional value, exhibit functional and technological properties and can significantly affect the quality indicators of yogurt. To confirm this, the possibility of complete replacement of the structure stabilizer in the composition of yoghurt with micellar casein and spelled flour, both separately and in various ratios, was studied. As a single criterion for optimizing the recipe composition of yoghurt at various ratios between casein and spelled flour, product quality indicators were used: the degree of syneresis, effective viscosity, organoleptic indicators.
