Документ 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), TetianaIn 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.Документ Scientific explanation of the composition and technological modes of manufacture of dairy ice cream with vegetable puree(2019) Sapigа, Victoria; Polishchuk, Galyna; Osmak (Fedchenko), Tetiana; Mykhalevych, Artur; Maslikov, MaximThe 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.Документ Cryoprotective ability of starch syrup in the composition of aromatic and fruit-berry ice cream(2019) Polishchuk, Galyna; Bass, Oksana; Osmak (Fedchenko), Tetiana; Breus, NataliaFor 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.
