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
