Technology of processing cattle bones into meat and bone paste and the study of quality indicators

Abstract

Bone disposal is one of the important tasks for modern meat processing enterprises aimed at responsible consumption and reducing the amount of food waste in the meat industry. The purpose of the study is to study the physico-chemical, microbiological and food safety indicators of the obtained meat and bone paste. The paper presents the technology of processing cattle bones into meat and bone paste. Physico-chemical analyses were carried out, a protein content of more than 10 g, fat of more than 6 g, carbohydrates of less than 1 g was detected per 100 g. Microbiological studies and analysis of the food safety of meat and bone paste carried out on the basis of accredited laboratories according to GOST methods prove that meat and bone paste meets the requirements for meat products. The content of QMA&OAMO is less than 1*105 CFU/g, the content of bacteria of the E. coli group was not detected. The technology of obtaining meat and bone paste from the rib bones of cattle has been studied. Microstructural analysis revealed the presence of bone plates with a size of up to 1 mm. Thus, according to the technology of bone processing, a meat and bone paste was obtained suitable for use in the technology of meat products for the purpose of enrichment with mineral and protein substances. The need for deeper grinding of bone particles was found.
