摘要
随着消费者膳食结构的改变和安全意识的增强,动物源性食品的产地来源已成为人们关注的焦点问题之一。食品的产地溯源是食品追溯体系中重要的组成部分,它既有利于保护消费者的利益,保护地区品牌和特色产品,确保公平竞争,又能有效地实施产品召回,防止食源性病原菌的扩散。稳定性同位素分析、矿物元素含量分析以及化学成分分析法被认为是进行食品产地溯源的有效技术手段,具有很好的发展前景。本文主要综述几种溯源技术的基本原理,介绍其在动物源性食品产地溯源中的应用现状及存在的问题,并对今后的发展提出相关建议。
Due to the change in diet habits and increasing health awareness,consumers are paying tremendous attentions to the geographical origin of animal-derived food products.As one of the most important parts in food traceability system,geographical origin of food products can be used to not only protect interests of consumers,regional brand and specialty products for ensuring fair competition,but also effectively implement product recall for preventing against the transmission of food-borne pathogens.Analyses of stable isotopes,trace elements and chemical compositions of foods are effective analytical tools to trace geographic origin of food products,which exhibits quite prospects.In this paper,current development status quo and problems in the determination of geographical origin of animal-derived foods,and basic principles of these methods are discussed.The future development directions are also proposed.
