By analyzing the differences of mineral element contents in dried tangerine peel from different producing areas, combined with multivariate statistical analysis, the effective origin traceability indexes based on mineral element fingerprint analysis technology were selected to construct its discrimination model of different origin identification. In this study, 206 dried tangerine peel samples were collected from three different producing areas as Guangdong, Fujian and Chongqing. The contents of 32 mineral elements were determined by inductively coupled plasma mass spectrometer (ICP-MS) and inductively coupled plasma atomic emission spectrometer (ICP-AES). Combined with analysis of variance, principal component analysis, linear discriminant analysis and orthogonal partial least squares discriminant analysis, a discriminant model of dried tangerine peel producing area was established. The results showed that 26 of the 32 mineral elements in the dried tangerine peel samples had significant differences between G
