The article is dedicated to the aspects of meat raw materials preservation. It is known that during the long meat preservation, different changes are taking place. These changes are subject to meat peculiarities, term and time of preservation. They lead to a meat mass reduction and product quality deterioration: muscles tissue changes its color because of myoglobine concentration change in the upper layer (as a result of moisture evaporation) and formation of metmyoglobin. Problem of raw material loss reduction and quality preservation is very important in meat products technology. The article presents a research for determination of intensity of meat cooling models, which depends on product size, temperature and air velocity. Speed of the processes that impacts the quality of the meat is significantly lower in the cooled products. The subject of the article is a research of dynamic of the density of heat flow during the cooling of meat samples. It is proved that the energy transfer due to emission does not affect meat shrinkage. Therefore, increase of heat flow share due to emission could improve the cooling time. It is determined that the speedy cooling process of meat provides its good marketable conditions, persistent film of predrying that improves terms of meat products preservation.
