Olive oil

Olive oil is a vegetable oil obtained by pressing whole olives (the fruit of Olea europaea, a traditional tree crop of the Mediterranean Basin) and extracting the oil. It is commonly used in cooking for frying foods, as a condiment, or as a salad dressing. It can also be found in some cosmetics, pharmaceuticals, soaps, and fuels for traditional oil lamps. It also has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine, with wheat and grapes. Olive trees have been cultivated around the Mediterranean since the 8th millennium BC. In 2022, Spain was the world's largest producer, manufacturing 24% of the world's total. Other large producers were Italy, Greece, and Turkey, collectively accounting for 59% of the global market. The composition of olive oil varies with the cultivar, altitude, time of harvest, and extraction process. It consists mainly of oleic acid (up to 83%), with smaller amounts of other fatty acids including linoleic acid (up to 21%) and palmitic acid (up to 20%). Extra virgin olive oil (EVOO) is required to have no more than 0.8% free acidity, and is considered to have favorable flavor characteristics.
