稳定同位素及矿物元素分析在谷物产地溯源中应用的研究进展
|
摘要
产地溯源是谷物真伪鉴别的重要研究内容之一。稳定同位素及矿物元素分析技术具有灵敏度高、可靠性强等优点,通过关联分析谷物中的稳定同位素、矿物元素信息与谷物的产地环境、种植方式等,并借助化学计量学手段进行分类、判别、建模等,可达到产地溯源的目的。本文系统分析了近10余年国内外有关稳定同位素及矿物元素分析技术在谷物产地溯源中的研究进展,在此基础上提出当前谷物产地溯源存在的问题,及今后稳定同位素和矿物元素分析技术在谷物产地溯源中的发展方向和研究重点。
Tracing the geographical origin of cereal grains is an important part of identifying their authenticity.Stable isotope and mineral element analysis have the advantages of high sensitivity and reliability,and the association of the information obtained with growing environmental conditions and planting methods followed by chemometric classification,discrimination and modelling allows to trace the geographical origin of cereal grains.In this article,we provide a systematic review of the recent advances over the past more than one decade in the application of stable isotope and mineral element analysis in tracing the geographical origin of cereal grains.Meanwhile,we discuss the problems existing in tracing the geographical origin of cereal grains,and propose the future prospects and research priorities for the application of stable isotope and mineral element analysis in this field.
