摘　　要：有机食品有效追溯技术的缺失给有机食品市场监管带来巨大困难。稳定同位素丰度作为食品生长环境(土壤、水、大气、肥料、饲料等)的"自然指纹"的特性使其近期在有机食品追溯中受到极大关注。作者在查阅大量有关稳定同位素溯源有机食品的相关文献的基础上,综述了稳定同位素的概念、用于有机食品溯源的原理以及在植物性和动物性有机食品溯源中的应用情况。最后,就当前稳定同位素溯源技术的局限性提出了今后的研究方向。The lack of effective methods for tracing organic foods brought about a lot of difficulties in inspecting and governing the market of organic foods. Because the abundance of stable isotopes provides a natural fingerprint for foodproducing environment(soil, water, air, fertilizer, feed, etc.), stable isotope technology has attracted much attention for its application in tracing organic foods. This article summarizes an extensive review of the available literature regarding the concept of stable isotope as well as the principle and applications of stable isotope technology in tracing organic plant foods(vegetables, fruits and cereals) and organic animal foods(meat, milk and egg). In addition, the limitation and future research directions of this technology in tracing organic foods are proposed in the present work.
