Authentication of the protected designation of origin “Kaki Ribera del Xúquer” from its mineral profile
Abstract
Protected designation of origin (PDO) “Kaki Ribera del Xúquer” samples were discriminated from those produced in other five origins concerning: towns surrounding Valencia, Alicante, Andalucía, Castellón and also Ribera, produced outside the PDO frame. Multivariate analysis tools; such as principal components analysis (PCA), hierarchical cluster analysis (HCA), linear discriminate analysis (LDA) and classification and regression trees(CARTs) were evaluated in order to achieve a correct sample classification of the six sample origin groups considered. Chemometric analysis was conducted with 14 variables (content of different elements in mg kg-1, determined by ICP-OES and ICP-MS). HCA and CART cannot authenticate the origin of kaki fruits at 100 %; CART provided a separation of 79 % for the PDO samples. PCA only discriminated well the samples as a function of their different harvest but LDA provided quite satisfactory results obtaining a classification rate of 100 % for samples ofthe calibration set and 67 % for those included in the validation set.Downloads
