Annotation. This article presents the analysis of marketing environment of the enterprises that produce yogurt products in Ukraine. In order to carry out a deeper analysis of the marketing environment of the new yoghurt drinks with a balanced composition of the major nutrients in food and increased probiotic properties, PEST and SWOT-analyses were conducted, they identified environmental factors that have favorable and adverse effects as well as internal strengths and weaknesses of the new product. Based on the results of marketing research of consumer preferences, the core audience of new yoghurt drink with a balanced chemical composition and the elevated concentration of Bifidobacteria were defined. The received results led to justification of the expediency of elaboration of new yoghurt drinks with probiotic properties and balanced composition of basic food nutrients as well as to formulation of a strategy of new product promotion on the consumer market of Ukraine.

The publication presents data on the effect of polysaccharides as cryoprotectants on changes of the lipid fraction of quick-frozen semi-finished products during storage. Since the structure of minced systems is formed as a result of the destruction of the native structure of the meat and the formation of a new secondary structure, it is important to establish the effect of cryoprotectants on the key functional and technological properties of meat systems after freezing, and in the process of storage. Based on studies of the kinetics of the oxidation of fat and accumulation data on the accumulation of the primary and secondary products of oxidation inhibition of oxidative processes has been found.

The article is based on research of the protein components of different nature analysis. The possibility of their use as components of protein and fat emulsions for the purpose of modeling their optimal formulations for use in the composition of meat pates was proved. Rational individuals’ emulsification process parameters, which guarantee high-quality homogeneous emulsions, were found. The samples of protein and fat emulsions using protein drugs and partial replacement of animal fats fortified blend of vegetable oils, determined by their biological value, rheological, functional and technological properties were investigated. Organoleptic analysis model of meat pates masses were analyzed and recommended percentage of protein and fat emulsions on recipes meat pates are shown.

For the recreational zone located in the Odessa region along the coast of the Black Sea it is expedient to use (as an additional source of water supply) the water received from air. It is shown that it is possible to receive water from air by means of conditioners which it is much placed on recreation facilities and sanatoria. As water from air may contain various dissolved substances, it is necessary to investigate its quality. It is important to know it for development of technology of water treatment. Results of research of quality of water of two types are presented. Samples are received under different service conditions of conditioners. In samples indicators of epidemic safety, and also sanitary and chemical indicators of safety and quality of the water received from air are defined.

This work is dedicated to the substantiation of development of technology of fruit and vegetable mousses using wheat starch and surfactant – Tween 20. The innovative idea of product with foamy structure was expounded, the implementation of which will allow to provide obtaining of the final product with stable quality indicators, new consumer characteristics and will give an opportunity to carry out the production technological process with distinct industrial signs. The foaming capacity and foam stability of “wheat starch-Tween 20” model systems depending on the heat treatment temperature and starch concentration were investigated. The rational foaming zone was determined that will allow to obtain foamy structure of mousses. The model systems behavior was studied by the determining of their viscosity. It was confirmed that the controlled regulation of dynamic phase transitions of starch with surfactant provides food systems’ colloidal stability.

In this article there is analysis of condition of stone fruit crops in fresh during their rotative movement on immobile perforated surface of cylindrical coating under field of centrifugal forces aimed at division onto semi-product (flesh) and waste (stones). Division is being performed via separation of flesh fragments from stones by hole edges. Separation intensiveness (productivity of the process) depends on structural-mechanical properties of fruit fleshes and their rotative speed. On the example of separate fruit it has been experimentally proved that besides rotative movement on inner surface of the coating there is rotative movement of a fruit around its own axle what promotes even separation of flesh. Such a rotation is typical for fruits with maturity stage even throughout the volume, otherwise breach of skin with following flesh separation occurs locally. Experimental researches carried out with apricot fruits and cornel have shown that productivity of the process of fruit separation depends of strength features of tissues and rotative speed of blades. Offered way of processing is carried out in nonstop mode and may be realized for all types of stone fruit crops independently on association between flesh and stone.
