Modern methods for identification of sturgeons caviar

Abstract

Solving the current problems of improving the quality and safety of food fish products is possible only if modern and objective methods of analysis are used. Ensuring the proper quality and safety of wild fish products produced by enterprises is possible through compliance with interstate and national standards and regulatory documents. Currently operating GOST 30812 "Raw materials and food products. The method of identifying sturgeon fish caviar "based on the establishment of morphological features of sturgeon fish caviar is the result of research work carried out by the Kasprybtestcenter and the Russian Academy of Sciences for the period 1997-1998. The morphological features of sturgeon fish caviar specified in the standard depend on various factors, and do not allow to establish belonging to the species. Morphological signs of caviar (grain size, cytogenetic structure) are changing indicators that depend on many factors that affect the physiological state of fish during cultivation. Modern studies conducted by the standardization and rationing group of the Volga-Caspian branch of Russian Federal Research Institute of Fisheries and oceanocraphy together with the laboratory of molecular genetics of Russian Federal Research Institute of Fisheries and oceanocraphy indicate that the more reliable way to identify caviar is to establish molecular genetic features. Genetic features are a stable criterion that reflects the hereditary material of parents. Developed an updated standard "Fish food products. Method for identifying the caviar of fishes of the sturgeon family. " The development of identification methods is based on the use of a complex of visually detectable signs of the macro and microscopic structure of the eggs of sturgeon and paddle-bearing fish species and the molecular genetic method Updated standard "Raw materials and food products. The method of identification of sturgeon fish caviar", supplemented by the modern molecular genetic method of identification of sturgeon fish and oatmeal, will provide a regulatory and technical basis for the functioning of the traceability system from the place of obtaining raw caviar to the store counter, which will significantly reduce the share of illegal, counterfeit and falsified products the functioning of the traceability system from the place of receipt of raw caviar to the store counter, which will significantly reduce the share of illegal, counterfeit and counterfeit products.
