        Geographical origin discrimination of pepper (Capsicum annuum L.) based on multi-elemental concentrations combined with chemometrics

        Jian Zhang,Ruidong Yang,Rong Chen,Yuncong C. Li,Yishu Peng,Xuefeng Wen 한국식품과학회 2019 Food Science and Biotechnology Vol.28 No.6

        The concentrations of twenty-four elements intwenty-five peppers from three cultivated regions inGuizhou Province (China) were analyzed. The chemometricdata processing, including one-way analysis ofvariance, principal component analysis, linear discriminantanalysis (LDA), and orthogonal partial least squares discriminantanalysis (OPLS-DA) were executed to differentiatethe peppers. Consequently, the contents of 16elements (Arsenic, Ba, Cu, Co, Cr, Ni, Pb, Sn, Sb, Mo, Sr,Y, Zn, Ca, P, and Fe) were significantly different amongthe three regions (p\0.05). The correct discriminationrates of 25 peppers were 92.0% for LDA and 96.0% forOPLS-DA. The variable importance in the projection (VIP)values were ranged from 1.063 to 1.262 for seven elements(Tin, Fe, Zn, Y, Cr, Sr, and Mo) indicating that they playedan important role for the geographical origin traceability ofpepper. To sum up, multi-element concentrations togetherwith chemometric data-processing can be promising for thegeographical origin differentiation of pepper.
