Even though a method for certifying EVOOs’ geographical origin has not yet been established in the scientific literature, the discrimination of olive oil production on a geographic basis, also called geographical authentication, is becoming an important trend in scientific research, with different analytical chemistry approaches being applied, including elemental/isotopic, nuclear magnetic resonance (NMR), mass spectroscopy (MS), and energy-dispersive X-ray fluorescence (XRF), as well as organic analytical methods and organoleptic evaluation [ 22 , 26 , 27 , 28 ].
