Abstract:

Food traceability plays an important role in the management of food manufacturing, processing and consumption. As the major dietary protein source, the safety problem of meat products has acquired considerable importance. This article reviews the research progress of molecular markers, which are used in DNA trace technology among numerous technical methods for traceability. Three kinds of molecular markers such as AFLP, SSR and SNP markers are compared and SNP marker is considered the preferred molecular marker for animal identification.

Key words: traceability, DNA trace technology, AFLP marker, SSR marker, SNP marker
