Development of Technological Solutions for In-Depth Processing of Meat and Bone Waste at Meat Processing Enterprises

Introduction: The increase in meat production in the agro-industrial complex generates waste accumulation. One of the reasons is the lack of available recycling technologies. Technological solutions for processing meat and bone waste are proposed, allowing to obtain a dry food ingredient and natural dry feed for non-productive animals at production facilities of any capacity.

Purpose: Development of technological solutions for the in-depth processing of meat and bone waste at meat processing plants, ensuring additional extraction of muscle pulp and the production of natural dry ingredients for food products and feed for non-productive animals.

Materials and Methods: The statistical method and comparative analysis were used to estimate the volumes of meat production and waste generation. The observation method was used to estimate the range of meat semi-finished products, and sensory analysis was used to determine their quality and the quality of dry feed. The experimental method was used to develop technologies for processing meat and bone waste. The rheology of dry feed was determined on the "Structurometer-ST2", and the amino acid composition was determined by mass spectrometry on the LCMS-8060 device. The presence of fiber in feed systems was determined by light microscopy. Data processing was carried out using Microsoft software.

Results:   The analysis of literary data showed a direct connection between the increase in meat production and the environmental sustainability of enterprises. The insufficiency of waste processing technologies is indicated and a promising market segment for their application is noted - the production of feed for unproductive animals. Marketing research has shown some deviations in the quality of meat and bone semi-finished products that can increase consumer waste. The composition of the recipes and the required parameters of the feed production technology are experimentally substantiated. A technology for in-depth processing of meat and bone waste with the production of dry meat granules and dry feed for unproductive animals has been developed. The compliance of dry feed indicators with regulatory requirements has been confirmed.

Conclusion: A universal technology has been developed that ensures the production of additional muscle pulp from meat and bone remains, guaranteeing the disinfection of raw materials, allowing to expand the boundaries of animal feed production and enhance waste recycling. New products have been obtained - meat granules and dry animal feed. The method gives enterprises the prospect of organizing a closed production cycle and obtaining added value. The study has limitations in application, due to the use of laboratory conditions for conducting the experiment and a limited sample of materials, which may differ in the results when they are obtained in industrial production.
