    Study of water freezing in low-fat milky ice cream with oat β-glucan and its influence on quality indicators
    (2023) Buniowska-Olejnik, Magdalena; Mykhalevych, Artur; Polishchuk, Galyna; Sapiga, Victoria; Znamirowska-Piotrowska, Agata; Kot, Anna; Kaminska-Dwórznicka, Anna
    The work is devoted to the study of the functional and technological properties of oat β-glucan in low-fat milky ice cream (2% fat) in comparison with the stabilization system Cremodan® SI 320. β-glucan (0.5%) has a greater effect on the cryoscopic temperature of ice cream mixes than Cremodan® SI 320 in the same amount (decrease by 0.166 ◦C vs. 0.078 ◦C), which inhibits the freezing process of free water in ice cream during technological processing in the temperature range from −5 to −10 ◦C. Microscopy of ice cream samples after freezing and hardening shows the ability of β-glucan to form a greater number of energy bonds due to specific interaction with milk proteins. Analysis of the microstructure of ice cream samples during 28 d of storage confirms the ability of oat β-glucan to suppress the growth of ice crystals more effectively than Cremodan® SI 320. Oat β-glucan gives ice cream a rich creamy taste, increases overrun and resistance to melting, which brings this type of frozen dessert closer to a full-fat analogue (10% fat).

    Effect of natural ingredients on the structural-mechanical and physicochemical properties of ice cream mixes
    (2022) Sapiga, Victoria; Polishchuk, Galyna; Tomczynska-Mleko, Marta; Mleko, Stanislaw; Terpiłowski, Konrad; Pérez-Huertas, Salvador
    In modern nutrition, there is an increased consumer demand for low-calorie products. Meanwhile, ice cream of classic types is a product with a high fat content (10–16%). Therefore, there is a high demand on production of new types of low-fat or non-fat ice cream. An ice cream is treated as a low-fat product when it contains below 5% of fat. In the process of modifying ice cream recipes, the main task is to obtain a product with a characteristic creamy consistency and high resistance to melting, which is ensured by maintaining a certain balance between the content of free and bound water, the specified values of the cryoscopic temperature and other physicochemical parameters.

    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.

    The process optimization of protopectin enzymolysis of vegetable raw materials for its use in ice cream production
    (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.

    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.
