| Summary: | The search for new effective structure-forming agents of natural origin in order to improve the technology of fish molded products is an urgent scientific and industrial problem. In the course of the study, to obtain minced fish systems, frozen pollock and pink salmon have been used that meet the technical requirements of the current regulatory documentation. Mixtures of cryoconcentrates from seafood, rice and wheat flour, and the enzyme transglutaminase are used as structure-regulating additives. Cryoconcentrates have been made from cucumaria, squid, Pacific herring milt, octopus skin, seaweed, and scallop mantle. The introduction of dry powdered cryoconcentrates of seafood, containing a significant amount of protein substances, has contributed to the binding of water and an increase in the water-retaining capacity of minced pink salmon and pollock. Based on the results of studying the physical, chemical, rheological and organoleptic properties of dispersed minced fish systems, rational amounts of structure-regulating additives have been established: seafood cryoconcentrates – 4.0–5.0 %; transglutaminase – 0.5 %; rice flour – 2.0 %; wheat flour – 1.0–2.0 %. Molded fish products (cutlets, sausages) containing structure-regulating additives had high organoleptic properties after heat treatment. The results of the research should be used in the development of formulations of fish dispersed compositions in the technologies of molded, emulsion and structured products. The established high water-binding capacity of seafood cryoconcentrates justifies the need to study them as natural cryoprotectors in refrigeration technologies. Поиск новых эффективных структурообразователей природного происхождения с целью совершенствования технологии рыбных формованных продуктов является актуальной научной и производственной проблемой. В ходе исследования для получения рыбных фаршевых систем использовались мороженые минтай и горбуша, соответствующие по техническим требованиям действующей нормативной документации. В качестве ... |
