A multi-methodological protocol to characterize PDO olive oils
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
