Abstract

At present, the problem of the quality of animal products occupies an important place in our country and throughout the world. This is due to the increasing influence of technogenic factors on the environment, crops and productive animals. One of the main indicators of the quality of meat is its freshness. The existing traditional methods for determining the freshness of meat, despite the rather long practice of their use, are generally inefficient, subjective, and do not differ in high sensitivity and specificity. One of the problems of a reliable assessment of meat sold on the markets is the identification of dystrophic and edematous changes in the muscle tissue of slaughter animals, in the presence of which the meat is subject to culling. Signs of swelling of muscle tissue are practically not detected by generally accepted laboratory methods. The aim of the study was to study the possibility of using the express method of freshness control during veterinary and sanitary examination of meat sold in the markets. The testing of an express method for determining the freshness of meat using bone marrow was carried out. It is shown that this express method allowed increasing the number of rejected samples with revealed signs of poor quality by 1,5 ... 2 times in comparison with the generally accepted organoleptic and physicochemical research methods. It has been shown that with the help of express analysis of muscle tissue, it is possible to reliably determine the poor quality of meat associated with pathological processes in the body or with the development of signs of spoilage. Such express methods have a certain prospect of using in veterinary sanitary examination laboratories at markets and fairs, as well as in production laboratories of meat processing enterprises.
