1. Introduction Olive oil (OO) is a vegetable oil obtained from olives, the fruits of the olive tree (Oleaeuropaea L.; family Oleaceae). The cultivation of olive trees, harvest of olives, and production of OO have been linked to the history and culture of some of the most ancient Mediterranean civilizations [1,2]. Today, OO is still mainly produced and consumed in countries surrounding the Mediterranean Sea. Approximately 70% of OO production is from Mediterranean countries.
