Olive oil is a liquid fat obtained from olives (the fruit of Olea europaea; 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.
Extra-virgin olive oil is made from pure, cold-pressed olives, whereas regular olive oil is a blend, including both cold-pressed and processed oils. … Any cold-pressed oil that doesn’t meet extra-virgin standards is then refined to get rid of undesirable impurities, giving the oil a more neutral flavor and lighter color.
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 is required to have no more than 0.8% free acidity and is considered to have favorable flavor characteristics.
Olive oil can be flavored with herbs and spices, which you can steep in the oil for 10 days or so. If you’re using chili, you need far less time. However, it’s important to note that olive oil is not recommended for cooking — it should only be used cold, usually drizzled on salads and other foods. Extra-virgin olive oil’s chemical structure and its large amount of unsaturated fats make it very susceptible to oxidative damage when used for cooking. Whenever you need an oil to cook with, use coconut oil or grass fed butter.
