Abstract:

The quality of Italian extra virgin olive oils (EVOOs) was evaluated based on the profile and quantity of phenolic compounds (PPs), providing a specific fingerprint. A total of 68 EVOOs from 11 Italian regions were analysed using high-performance liquid chromatography coupled with a diode array detector and mass spectrometer. The obtained data were subjected to multivariate statistical methods. Further, PPs and lipophilic vitamins were analysed in vegetable oils of 6 different kinds using a square-wave voltammetry based on their anodic oxidation. Both analytical methods were compared and critically evaluated.
