Comprehensive evaluation of dry sausages
The lack of a comprehensive quality evaluation often leads to the fact that meat products do not correspond to their name in composition or are of poor quality. The purpose of our researches shows how the comprehensive evaluation of the quality parameters of dry sausages is important to identify the composition of their name, the recipe and regulatory requirements. Dry sausages of diff erent brands of “Braunschweig” and “Jewish” varieties have been studied. Comprehensive researches of quality parameters have been carried out by organoleptic, physic and chemical methods, which determined the pH, mass fraction of moisture, content of sodium chloride and nitrite; microbiological methods, including the determination of Escherichia coli group bacteria, E. coli, S. aureus and sulfi tereducing clostridium; as well as microstructure methods and PCR, which determined the quality of raw meat raw materials and its possible falsifi cations. It has been found as a result that none of the studied samples fully meets the regulatory requirements. In particular, one of the samples was unsafe due to the presence of Escherichia coli group bacteria and E. coli. In some samples additives based on animal proteins were found not indicated on the label, and with the help of PCR some samples have been found to have a mismatch in the composition of the original meat raw materials GOST. At the same time, according to the results of analysis by separate methods, many samples fully met the requirements of the standards. Thus, the results obtained confi rm the need for comprehensive researches of food products, since only such the evaluation can ensure their safety and quality.
