Analysis on the development trend of stable isotope research in the field of traceability of agricultural products

In recent years, the research on traceability of agricultural products (including authenticity identification and origin confirmation) has become a hot spot in the field of quality and safety of agricultural products, and stable isotope analysis technology is one of the most promising technologies in the field of traceability of agricultural products. In this paper, the research and development trend of stable isotope technology in the field of agricultural product traceability are discussed based on the related papers collected by Web of Science, China Knowledge Network, standards, patent and the database of National Natural Science Foundation of China as data sources until September 2020. Through analysis from multiple perspectives, it is found that China's research on traceability of agricultural products using stable isotope technology has reached the international advanced level, and many influential scientific research teams have been formed. Stable isotope technology plays an important role in judging the authenticity and tracing the geographical origin of agricultural products. Improving the standard system of stable isotope analysis, enriching the traceability database of stable isotope origin of agricultural products, and improving the traceability accuracy by combining new technologies are the future research directions of traceability of agricultural products.
