Protection of the quality products and particularly Protected Designation of Origin (PDO)/Protected Geographical Indication (PGI) foods is a strategic issue in the EU economy, in terms of protection of market competition and safety. Having reliable tools for the assessment of key parameters useful for the identification of authenticity and/or frauds is therefore of main interest.
An analytical approach including Panel Test, Isotope Ratio Mass Spectrometry (IRMS)
and Nuclear Magnetic Resonance (NMR) spectroscopy was proposed to characterize Italian “Colline
Pontine” PDO olive oils (40 samples) of two consecutive crop years. Our approach has evidenced
the high quality of these olive oils. Only 6 of 40 olive oils samples were defined as “defective” by the
official Panel Test due to the detection of negative sensory attributes. The low variability of isotopic
