Abstract
This article analyzes the results of studies on the nutritional value and biological value of fermented semi-smoked sausage. We studied the change in the quality of meat raw materials during the processing of beef of the first and second grades with propionic acid bacteria. Meat raw material was processed in the amount of 0,1 % at the ripening stage. Bacterial cultures cause rapid hydrolysis of meat biopolymers, which makes it possible to intensify the technological process. Domestic and foreign scientists have proved the correctness of the direction of using modern biotechnology, namely enzymatic, in order to increase the yield of finished sausages, reduce the duration of heat treatment, and increase their biological value and nutritional value. It has been determined that propionic acid microorganisms lead to the significant formation of free amino acids and volatile fatty acids, thereby improving the taste and organoleptic characteristics of the finished sausage product and speeding up the formation of the product consistency. Considering the fact that the propionic acid microorganism grows at low temperatures, has a high activity against pathogenic microflora, and also has the ability to increase the content of fatty acids, amino acids, vitamins, and minerals, effectively use microorganisms as starter cultures in the processing of meat raw materials.
