Olive Oil as seen by NMR and chemometrics

This article presents the results obtainable using high resolution NMR methods in the analysis of olive oil. Among these: the comparison between conventional and NMR analysis in the olive oil characterization; 13C NMR and the distribution of fatty chains on the glycerol moiety; the 1H NMR determination of minor components such as squalene, cyclo-arthenol and chlorophyll in olive oil; the geographical characterization of olive oils; the panel test and its relationship with NMR data. All these data, analysed by chemometric techniques, lead surprising results
