PROSPECTS FOR THE USE OF THE LIQUID FRACTION OF SNAIL PRODUCTION WASTE

The objective of the study is to examine the possible prospects for using the liquid fraction of snail production waste and its processing to reduce the degree of harm to the environment in accordance with the Federal Law of 24.06.1998 № 89-FZ (as amended on 14.07.2022) On Production and Consumption Waste. Re-inclusion of this type of raw material in the technological process allows production to obtain additional profit by excluding the cost item for waste treatment and disposal, in compliance with the legislation of the Russian Federation and with the simultaneous organization of a closed production cycle. Objectives: determination of the chemical, amino acid composition of the sample under study and study of its biological value. The object of research is the liquid fraction of production waste, which is a complex of flushing water and drains, residual contents of the gastrointestinal tract and mucus. Liquid waste obtained in 2023 during the processing of raw materials (removal of the snail body from the shell, separation of the leg from solid production waste) were frozen in a freezer at a temperature of –1...–25 °C under the conditions of VNIIOK – a branch of the Federal State Budgetary Scientific Institution "North Caucasus Federal Scientific Center". In this study, we did not use the generally accepted industrial technology, which includes the receipt of the studied raw material in an averaging tank with a mixer, its passage through a submersible pump with a cutting mechanism into a screw separator, since the structure of the biological mass was homogeneous. All studies were carried out according to generally accepted methods in the accredited laboratory "Feed and Metabolism" located in the Stavropol Region. The obtained results demonstrate the content of protein of 53.9 %; fat – 0.4; ash – 4.9 and nitrogen-free extractive substances (NFE) – 40.8 %, which indicates the feasibility of using the liquid fraction of snail production waste. The presented development contributes to the formation of a closed cycle of snail production, reflects a possible and promising solution to the problem of both solid and liquid fraction waste.
