"The purpose of the study was to give an overview of imported and traded gadoid fish species in the Czech Republic and to describe available methods for their authentication. With regard to different values and prices of various fish species, these may be adultered. Until recently, electrophoretic, chromatographic and immunological methods based on the analysis of proteins extracted from fish musculature seemed to be promising. Using these methods, various fish species can be identified in fresh, chilled and frozen products. However, they often fail in heat treated products. Molecular biology methods based on DNA analysis are more reliable and suitable for the analysis of fish product that have been heat treated during the production process." . "0375-8427" .
