At present, the issue of rational use of meat, taking into account the peculiarities of autolysis, is of particular importance, since the production of animals for meat processing increased, after slaughter of which significant deviations in the development of autolytic processes are found in muscle tissue. Therefore, a comparative assessment of changes in the indices of beef DFD and NOR, taking into account the influence of various freezing parameters, is highly relevant and is of scientific and practical interes...

The article deals with the stages of obtaining collagen hydrolyzate by means of biomodification of cattle rumen, as well as the method of its canning by freeze drying. The preparation of cattle rumen hydrolyzate (RHF) was carried out as follows: the scar was pre-rinsed in running tap water for 20 minutes to remove contaminants and mucus, scraping off muscle and adipose tissue; after the run-off of water (15?20 min), the raw material was ground on a top with a diameter of holes of the scoring grid of 2?3 mm. The gr...
