“…Тепер існує дуже обмежений асортимент продукції зі ставкових риб. Тому завдання створення технологій перероблення ставкових риб в консервну продукцію є актуальним і дозволить істотно розширити асортимент продукції рибопереробних підприємств (Bredikhina & Zarubin, 2019;Holembovska et al, 2021).…”

Taking into account the results of literature research on the nutritional value of quail eggs, it was found that the development of technology of fish pates with their use is relevant and has practical significance in the technology of production of fish products. The article presents the results of chemical composition, organoleptic evaluation and physico-chemical changes of fish pate with the addition of non-traditional raw materials and setting their shelf life. The expediency of combining freshwater fish with plant and animal raw materials to expand the range of biologically valuable food products is shown. Positive general impressions, harmonious, fishy and sweet-salty taste, showed the feasibility of combining quail eggs and vegetable raw materials with freshwater fish, as evidenced by high performance in appearance, taste and smell. According to the consistency of fish pate smeared and quite dense. It was found that in the experimental sample during storage are hydrolytic spoilage, which indicates the intensive hydrolysis of lipids and the accumulation of free fatty acids in these samples. In the prototypes, the hydrolytic damage gradually increases and only reaches the critical point by the end of the shelf life. Oxidative processes in the lipids of fish pastes were studied by changes in the accumulation of primary oxidation products – peroxides and secondary products – carbonyl compounds. According to the dynamics of changes in the peroxide content of lipids in pate, it was found that the control sample is not subject to storage for 5 days as well as the test sample, the fat content deteriorates and is characterized as non-storage. It has been experimentally established that the addition of non-traditional raw materials allows not only to improve the technology of pate production, but also to solve the problem of obtaining a product of high nutritional value. The authors found that the developed technology of fish pate will significantly expand the range of functional products based on natural ingredients, which will to some extent expand the current problem of processing raw materials in inland waters of Ukraine.

The expediency and prospects of using secondary fish raw materials from silver carp in the structuring agents technology have been substantiated. The combination of secondary fish raw materials and seaweed with different mechanisms of gelation has a targeted effect on the organoleptic, structural-mechanical, and physicochemical properties of food products. Accordingly, the expediency of adding the Black Sea alga cystoseira (2%) to optimize the mineral composition of the structuring agents and increase their jelly-making properties was established. Using experimental studies and multicriteria optimization, the optimal ratio of secondary fish raw materials – 40%; water – 60% and rational heat treatment – 150 min, at a temperature of 85 – 100 °C has been determined. An analysis and comparison of various preservation methods have confirmed the expediency of using the freeze-drying method of drying fish broths for the production of structuring agents, which allows to preserve of the original properties of the product, biologically active substances, reduce the mass of the dried product and increase the shelf life of the structuring agents. The optimal storage conditions have been determined – the ready-made structuring agents were packed in three-layer paper kraft bags and stored in a cool dry place at a temperature of 22 ±2 °C and relative humidity of no more than 70% for 12 months. It was found that the physical and chemical indicators of the structuring agents depend on the features of the structure, amino acid composition of fish collagen. The presence of the overwhelming number of high-molecular-weight molecules in the composition of the structuring agents and the preservation of the native structure determine high indicators of dynamic viscosity, dissolution time, and strength. As a result of the research, it was revealed that the high protein content largely depends on the amount of collagen in the secondary fish raw material, which has a positive effect on the gelling properties of the product being created.
