Olive oil is a liquid fat obtained from olives (the fruit of Oleuropein;family Oleaceae), a traditional tree crop of the Mediterranean Basin. The oil is produced by pressing whole olives. It is commonly used in cooking, whether for frying or as a salad dressing. It is also used in cosmetics, pharmaceuticals, and soaps, and as a fuel for traditional oil lamps, and has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine; the other two are wheat and grapes.

From the most traditional in which a stone mill is used, the press with straining and natural decanting in pools, to the most modern, where the two-phases centrifugation process is used. All of them have in common that they use only mechanical and physical procedures.
