Abstract： A real-time fluorescence PCR method was used to detect sesame-derived ingredients in sesame paste to identify the authenticity of prepackaged products. Three commercially available sesame paste products， one of which was labeled as not containing sesame ingredients， were selected and tested using a fluorescence quantitative PCR method. The results showed that the assay results were consistent with the product labels and the established assay was feasible.
