Abstract: Citri Reticulatae Pericarpium (CRP) is a good medicine and food homogeneous product, with high medicinal and economic value. However, CRP fraud often occurs in the market, including geographical origin mislabelling, variety counterfeiting and aging time cheating, which damages consumer interests. It is urgent to establish effective techniques for geographical origin traceability and authentication of CRP, in order to ensure safety and quality of CRP. In this paper, we provide a review of the research progress in the application of metabolomics, spectroscopy, DNA analysis, elemental analysis and intelligent sensory analysis in identifying geographical origin, variety, harvest period and aging time of CRP. Meanwhile, we compare and analyze the advantages and disadvantages of each technique, and propose the existing problems and future research priorities in the field of origin traceability and authentication of CRP.
