With the social development and the improvement of living standards, consumers’ requirements for the quality and safety of agricultural products have been continuously increasing. As one of the important means for identifying the authenticity of agricultural products, origin traceability has garnered widespread attention in recent years. Stable isotope analysis, characterized by its low sample requirement, high accuracy, strong applicability and resistance to human interference, has been widely employed in origin traceability research for various agricultural products. However, relying solely on stable isotope analysis sometimes fails to achieve the desired accuracy in traceability. Consequently, combining stable isotopes with other techniques has become a significant direction for improving traceability precision. Currently, the integration of stable isotopes with techniques such as multi-element analysis and organic component analysis has demonstrated effective application in origin discrimination for various agricultural products, including grains, fruits and medicinal herbs. This paper reviewed the research progress over the past 5 years regarding the combination of stable isotope analysis with other techniques in the origin traceability of plant-derived agricultural products. It summarized existing challenges in practical applications and offered insights into future development directions, aiming to provide a reference for achieving more accurate origin traceability of agricultural products.
