Abstract:

With the rapid growing demand and development of striding regional trade for famous, special, high-quality and novel agricultural products, consumers have shown more attention to information about the geographical origin information of agricultural products. Recently, an amount of successful exploratory researches have been conducted to identify the geographical origin of agricultural products (GOAP) with multi-element and isotopic fingerprint analysis at home and abroad. These researches all indicate that identification of GOAP can be done with fingerprint patterns of multi-elemental concentrations and isotope ratios (especially, hydrogen, oxygen, carbon, nitrogen, sulfur and strontium). The article summarizes the recent progress made in the abovementioned fingerprint analyses to identify GOAP of meat, dairy product, beverage material, cereal, grape wine, etc., so as to provide theoretical bases for relevant studies and protection of GOAP in the near future.

Key words: multi-element, isotope, agricultural products, geographical origin identification

摘要：

随着人们对名特优新农产品需求的快速增长和跨地区贸易的迅速发展，消费者对农产品原产地信息也越来越重视。近年来，国内外开展了一些应用多元素及同位素“指纹”分析技术对农产品进行原产地判定的探索性研究。研究表明利用氢、氧、碳、氮、硫、锶同位素比及多元素含量特征可对农产品进行原产地判定。综述了多元素及同位素“指纹”分析技术在肉品、乳制品、饮品原料、谷物、葡萄酒等农产品原产地判定中的研究进展，为未来相关研究的发展和农产品原产地保护工作提供理论基础。
