Application of Stable Isotope Technology in Tracing the Geographical Origin of Agricultural Products

Agricultural product traceability technology is a tracking and detection technique to protect regional brands and specialty products,prevent food adulteration and foodborne disease from spreading,ensure food safety,and reduce company recall costs. The establishment of an efficient food traceability system is the key to ensurement for food quality and safety. In recent years,stable isotope technology has been widely used to identify various agricultural products of different origins and food sources due to its advantages of no radioactivity,high sensitivity and reliability,which has become an effective means of tracking the source of food. The paper systematically expounded the application of stable isotope technology in geographic origin of various foods such as cereal grains,meat products,fruits and vegetables,fruit juices,wine,dairy products and aquatic products. The advantages and limitations of stable isotope technology in geographic origin of agricultural products in China was further analyzed. And its development prospect is forecasted,in order to provide reference for the establishment of Chinese agricultural product traceability system,and promote the application of stable isotope on tracing the geographical origin of food.
