Abstract

The article considers and studies the need to find and develop new sources of protein, as well as biologically active substances, methods of their production and processing, used both for obtaining livestock products and in other areas of human economic activity. One of the most promising areas is snail farming, represented by edible species of land snails. This article covers the development of a method for obtaining a new type of raw material from Helix pomatia (grapevine snail) and the study of its qualitative characteristics. All studies were conducted according to standard, generally accepted and developed practice. As a result of the research work, a method for obtaining the grapevine snail lyophilizate was developed, tested, proposed and implemented, which contributes to an increased content of biologically active substances, better nutritional value and high quality of the obtained products with a long shelf life. The study of the quality indicators of the products obtained by the developed method took place in compared with well–known and long-established techniques: the use of a dehydrator at a temperature of +35°C and a drying cabinet at +105°C. The analysis of the chemical and amino acid composition of the compared products from the grapevine snail showed superiority in crude protein content within 2.1–2.9 % absolute, therefore, essential amino acids in Helix pomatialyophilizate. Thus, the effectiveness of the established method for obtaining the grapevine snail lyophilizate with the prospect of using it in various industries and areas of production activity has been proven.
