title: Is authentication of regional and traditional food made of meat possible?
abstract: Authentication of regional and traditional food made of meat poses a significant challenge. It continues to be a very difficult task which requires employment of quite advanced analytical techniques. These products, despite a similar process of manufacturing, differ in taste and aroma. This happens due to the use of special breeds of animals, the application of appropriate feeding regimes as well as the effect of the place and climate. In order to perform correct identification of geographical origin, a good solution is to determine both stable isotopes as well as trace elements. It is essential to collect detailed meteorological and geochemical data and information about farming practices and to compare them with the obtained results. In a majority of cases, the performed identification is confined to species and the determination of the animal breed is very limited. In the case of individual breeds a comparative analysis of SNPs appears to present the highest potential, especially genes affecting the coat color of animals may serve as markers. Experiments confirm that genes responsible for pigmentation underwent mutations in individual breeds. Authentication on the basis of the manufacturing process appears to be easier to realize than tracing geographical origins.
