DEVELOPMENT OF FORMULATION AND TECHNOLOGY OF FISH CABBAGE ROLLS FROM OBJECTS OF COMMODITY AQUACULTURE
The article presents the results of marketing research of consumer preferences of fish culinary products in the Astrakhan market. It has been found that the overwhelming majority of respondents (90%) are potential consumers of these products. The perceptivity of using carp and silver carp meat as culinary products has been grounded. The technologies of fish culinary products processed from commercial aquaculture objects have not been fully developed and need to be improved taking into account the specific properties of raw materials. The improvement will help to increase the nutritional value of fish culinary products, to expand the assortment and to use raw materials rationally. Theoretical significance of the current research lies in the scientific justification of the formulation and technology of fish cabbage rolls produced from commercial aquaculture species, and the practical value includes the development of technological documentation for new products. Three formulations of fish cabbage rolls have been developed: with carp and dill; with carp and carrots; with silver carp and carrots. The complex organoleptic value of cabbage rolls prepared according to the proposed receipts was estimated in 20 points, which proves the high quality of fish culinary products. The indicators of biological value of protein components of fish cabbage rolls were: amino acid score, utilization rate, coefficient of rationality of the amino acid composition. It has been stated that cabbage rolls with carp and dill, with carp and carrots have a limited content of amino acid valine by 92% and 93%, and cabbage rolls from silver carp - by leucine and valine amino acids 68% and 74%, respectively. The coefficient of rationality of amino acid composition demonstrates the balance of essential amino acids in fish cabbage rolls in relation to the physiologically necessary norm. It has been found out that the ratio of fatty acids in cabbage rolls with carp and silver carp equals to the ideal fat. It has been established that fish cabbage rolls produced from commercial aquaculture objects are competitive among similar products and meet market requirements.
