Abstract: Driven by the booming organic agriculture and increasing consumer demand for healthy food, organic agricultural products have gained significant consumer favor due to their perceived advantages in safety, environmental friendliness, and nutritional benefits. However, motivated by economic gains, fraudulent practices in the market have occurred frequently, severely disrupting market order. Authentication is a crucial link in safeguarding the healthy development of the organic agricultural product market, necessitating ongoing research into reliable analytical identification technologies. Based on an extensive review of relevant literature, this paper systematically summarizes the principles, core bases, research progress and achievements of various identification techniques, including stable isotope analysis, spectroscopic techniques, chromatography-mass spectrometry, molecular biological techniques, and intelligent identification systems based on multi-technology integration. It analyzes the current challenges and future trends in the authentication of organic agricultural products, aiming to provide references for the innovative optimization of identification technologies and the enhancement of industry supervision.
