In this study, four Italian extra virgin olive oils (EVOOs) were chosen: two with a local (Emilia–Romagna) designation of origin (L) and two of non-local origin (G). One of the local oils (L1) was monovarietal, from olives of the cultivar “Nostrana di Brisighella”. The other local oil (L2) was a blend of two olive cultivars, Leccino (50%) and Frantoio (50%). Two more oils, labeled as “obtained from 100% Italian olives”, were chosen: G1, “Novello” from Sicily; and G2, generic regular quality oil. All oils were produced in 2010 except oil G2, the production year of which was not indicated. The EVOOs were tested at the end of November 2010.
