The article systematizes information about the sources of β-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 β-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 β-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 β-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 β-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.

Introduction. 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. Materials and methods. Object of researchice cream technology. The subject of the studyvegetable 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 meltingthe melting time of hardened ice cream samples, the air bubbles sizethe microscopy of soft ice cream samples in the chamber Goryaev, ice cream overrunby the weight method. Results and discussion. Scientifically confirmed the expediency of using in composition of the milk ice cream vegetable puree with a high content of soluble pectin due to thermoacid hydrolysis protopectin. 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 cryoscopic temperature of ice cream blends, which makes it possible to apply commonly accepted freeze modes to obtain a product of guaranteed quality. Conclusions. A new kind of dairy ice cream with concentrate vegetable puree of high nutritional value can be recommended for widespread introduction in accordance with the classical technological scheme of production with refinement of maturating regimes.

The work is devoted to solving the actual problem of the dairy industry -complex processing of food raw materials, expanding the range of dairy and milk-containing products of high nutritional value due to enrichment of protein, pro-and prebiotics, rational use of production resources by reducing the the technological process duration. The aim of the research is to substantiate the composition of a new type of acidophilic-whey ice cream of high nutritional value due to enrichment with a complex of proteins, probiotic sourdough and pectin-containing vegetable paste. The main tasks of scientific work are: development of a scientifically based formulation for a new type of ice cream to expand the range of products that will improve the nutrition structure of the Ukraine`s population. The methods used to study the organoleptic and physico-chemical indicators of blends and ice cream are well known and presented in the article. The method of production of sour milk ice cream and the choice of dairy raw materials for obtaining a fermented base was theoretically substantiated, the functional and technological properties of protein concentrates and their compositions in ice cream formulations were studied, the rational content of protein in ice cream was established, also the expediency of using pectin-containing vegetable paste in acidophilic-whey ice cream was proved.

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).
