Abstract(s)

Olive oils may be graded according to their overall physicochemical composition and sensorial attributes as: -extra-virgin olive oils (EVOOs); -virgin olive oils (VOOs); - lampante olive oils (LOOs). Olive oils are quite prone to frauds thus there are legal protection EU Commission regulations: - EU Commission Regulation, 1991; - EU Commission Regulation, 2011. Maximum levels are established for: - Chemical and physicochemical parameters (e.g., free acidity, peroxide value, UV extinction coefficients and alkyl esters content)i -Sensory attributes (presence/absence of organoleptic defects, fruity sensation and positive attribute).
