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
samples chemical composition.
Method:
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 clusters stand out, which
seem to consistently group samples in relation to the cultivars and cultivation areas that share the territorial proximity
(same province).
Conclusions:
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 to guarantee it
to the consumers.
The paper is about the reorganisation of the Authorities for book and archives of the Italian Ministry of Cultural Heritage. After an examination of the new legislation, some procedure inconsistencies are outlined and the role of librarians is discussed.
