Background and Objectives: In this article, a comprehensive study was carried out for Sicilian and Calabrian olive oils authenticity evaluation through chemometric analyses, correlating botanical and geographical origins with the samples' chemical composition. Methods: A total of eighteen Sicilian and Calabrian (southern Italy) olive oil samples were analyzed through gas chromatography (GC). Results: The fatty acids concentration in the investigated samples followed the subsequent order: oleic (C18:1) > palmitic (C16) > linoleic (C18:2) > stearic (C18) > palmitoleic (C16:1) > linoleic (C18:3). The 2D Scatterplot (Principal Component Analysis) showed that, among the analyzed oils, six clus-ters stand out, which seem to consistently group samples in relation to the cultivars and cultivation areas that share the territorial proximity (same province). Conclusion: Experimental results demonstrated that it is possible to strictly relate, through the PCA, olive oils to their geographical and botanical provenance, thus becoming a useful tool for evaluating product authenticity and guaranteeing it to the consumers.

Abstract

Background and Objectives: In this article, a comprehensive study was carried out for Sicilian and Calabrian olive oils authenticity evaluation through chemometric analyses, correlating botanical and geographical origins with the samples' chemical composition. Methods: A total of eighteen Sicilian and Calabrian (southern Italy) olive oil samples were analyzed through gas chromatography (GC). Results: The fatty acids concentration in the investigated samples followed the subsequent order: oleic (C18:1) > palmitic (C16) > linoleic (C18:2) > stearic (C18) > palmitoleic (C16:1) > linoleic (C18:3). The 2D Scatterplot (Principal Component Analysis) showed that, among the analyzed oils, six clus-ters stand out, which seem to consistently group samples in relation to the cultivars and cultivation areas that share the territorial proximity (same province). Conclusion: Experimental results demonstrated that it is possible to strictly relate, through the PCA, olive oils to their geographical and botanical provenance, thus becoming a useful tool for evaluating product authenticity and guaranteeing it to the consumers.
