Abstract


The study considers a problem of repeated contamination of delicious products, ready for consumption. The aim of the work is to study the repeated thermal processing of a ready vacuum-packed whole-muscular meat product for inhibiting a surface microbiota.

Today it is urgent for the meat industry, because it influences safety and quality, and also limits a storage term of a product.

After bringing a meat product to culinary readiness by thermal processing, it has an unessential amount of microbiota. Microorganisms, including pathogenic and conventionally pathogenic ones, fall on a product after its cooking at cutting, preparation to package and at the package stage itself. Microbiological contamination of a ready meat product results in fast spoilage and is a serious problem for producers, because the microbiota growth shortens its storage life. In its turn, it results in a refuse of a consumer to buy this product and great economic losses for producers.

The study is directed on a possibility of solving a problem of contamination of a whole-muscular delicious meat product. The solution is in package of a ready product under vacuum and short-term heating at a high temperature.

The work is devoted to the complex study of an influence of repeated pasteurization on safety and quality of a product. There was studied an influence of the repeated thermal processing (post-pasteurization) on microbiological, physical-chemical and also organoleptic parameters of a delicious meat product.

The special attention is paid to an influence of post-pasteurization regimes on a microbiological condition of studied samples. Studies of a total amount of microbiota and also the presence of sanitary-representative microorganisms were conducted.

It has been proven, that the use of post-pasteurization essentially inhibits a number of microorganisms, and also doesn’t influence physical-chemical parameters outlook of a product and organoleptic characteristics.

Based on studying an influence of post-pasteurization, it has been established, that inhibition of a microbiota essentially influences safety and prolongs the storage term of a product.
