Research Progress in Meat Adulteration Detection by Molecular Biology

Many adulterations of meat have taken place in various countries of the world every year usually driven by economic interests. A variety of nucleic acid,protein and lipid based technology has been developed and actually applied for meat authenticity detection. During past two decades,with the rapid development of molecular biology detection technology,there was a truly sensitive and efficient detection method for meat products identification. At present,the molecular biological detection methods mainly include traditional PCR,multiplex PCR,restriction fragment length polymorphism PCR,DNA hybridization and gene chip,real-time PCR,digital PCR and DNA barcode,among which real-time PCR is now commonly used technical means on the identification of meat products for the regulatory authorities. This article mainly introduced the studies and application progress of seven technologies and probes into the future research directions,providing a brief picture for the relevant regulatory authorities and scientific researchers.
