肉产品分子溯源标记的研究进展

Research Progress on Molecular Markers for Meat Products Traceability

食品溯源管理对食品生产、加工和消费过程起到重要的监管作用。肉产品作为饮食中主要的蛋白质来源,其安全问题受到高度重视。在众多的溯源技术方法中,本文介绍了DNA溯源技术使用的分子标记的研究进展,对AFLP标记、SSR标记、SNP标记3类标记进行分析比较,并指出SNP标记必将成为动物身份识别首选的分子标记。

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.
