The traceability of grain origins and authenticity identification have garnered increasing attention from consumers. In recent years, significant progress has been made in research on Oryza sativa origin traceability and authenticity identification, encompassing technologies such as stable isotope analysis, mineral element profiling, spectroscopy, volatile compound analysis, DNA-based methods and metabolomics. This paper reviewed the research progress on the integration of various technologies with multivariate analytical methods in the traceability of origin tracing and authenticity identification of Oryza sativa, while discussed the principles, application scope, effectiveness and advantages/disadvantages of different techniques. By incorporating the geographical, varietal and organic characteristics of Oryza sativa, it summarized the latest developments in Oryza sativa origin traceability systems. The study aimed to provide reference foundations for Oryza sativa quality control and food safety, promote the establishment of traceability databases, and highlights its critical implications for safety regulation, rights protection and brand safeguarding in the Oryza sativa industry.
