Product properties and quality of food chicken eggs
An important condition for the production of high-quality food eggs is the improvement of control methods, strict observance of the regulated technological modes of production and storage, a comprehensive analysis of the causes of the decline in quality and the appearance of defects. The purpose of the research was to study the commodity properties and quality of edible chicken eggs of the first category from different manufacturers (Chelyabinsk Poultry Farm, Pyshminskaya Poultry Farm, Komsomolskaya Poultry Farm), selling their products in the Chelyabinsk retail trade. Production tests were carried out in the laboratories of the South Ural State Agrarian University and South Ural State University. It was determined that the packaging of eggs was clean, whole, undeformed, consumer labeling of labels and products fully complied with the requirements of GOST 31654-2012, GOST R 51074-2003 and TR TS 022/2011. Commercial quality and biophysical properties of eggs complied with the requirements of the “Rules of veterinary and sanitary examination of poultry eggs” and GOST 31654-2012. Safety indicators were within the norms of SanPiN 2.3.2.1078-01 and TR TS 021/2011. The best consumer characteristics (color and taste of yolk) and nutritional value (content of proteins and fats) were supplied by the products supplied to the trading network by the Tyumen manufacturer, namely the Pyshminskaya Poultry Farm. Perm food-grade chicken eggs (“Komsomolskaya poultry farm”) were larger in mass, and rounded in shape than others, with shells without microcracks. Products from Chelyabinsk Poultry Farm had averaged quality indicators, but in a comparative aspect, they differed in microbiological stability and toxicological safety.
