AB Four essential elements (Mn, Ni, Zn, and Cu)and their molecular-size distribution patterns have beendetermined, for twenty four samples of pine nuts from eightareas in Spain and Portugal (Huelva, Cádiz, Badajoz,Cataluña, Castilla, Madrid, Faro, and Coimbra), by sizeexclusionliquid chromatography (SEC) coupled on-line toUV and inductively coupled plasma mass spectrometric(ICP–MS) detection. The variability observed in totalelement content and the size-exclusion profiles of elementsin samples from distant areas were considered as chemicaldescriptors for characterization of geographic origin. Apattern-recognition technique, the display method principalcomponent analysis, was used as visualization technique todetermine the provenance of the pine nuts collected. Theresults obtained confirmed that size fractionation profilesgive more information for assessing the provenance of pinenuts than the total elements composition traditionally usedfor this purpose. Combination of these chemical descriptorswas the most suitable choice for the samples studied.
