基于标志物的食品溯源技术研究进展

食品产地溯源是食品质量与安全追溯体系的重要组成部分，有利于保护原产地标志，保护地区名牌，保护特色产品，确保公平竞争，增强消费者对食品安全的信心。基于标志物的鉴别方法具有高灵敏度，高鉴别度，高通量的特点，因此在食品溯源分析中有极大的价值。本文综述了近年来几种常用基于标志物的食品溯源技术在不同种类食品中的应用研究进展，分析了各种方法的优势和不足，并展望了今后食品溯源技术研究的发展趋势，开展不同高灵敏度特征标志物的同步检测在未来食品溯源分析中更有前景。

Review of Food Traceability Technology Based on markers

Food traceability is an important part of food quality and safety traceability system, which is conducive to the protection of origin marks, regional famous brands, special products. Marker based identification method has high sensitivity, discrimination and throughput, so it has great value in food traceability analysis. In this paper, the research progress of several commonly used marker-based food traceability technologies in recent years was reviewed, the advantages and disadvantages of various methods were analyzed, and the development trend of food traceability technology in the future was prospected. The synchronous detection of different high-sensitivity characteristic markers has more prospects in the future food traceability analysis.
