Olive oil is a fruit oil obtained from the olive (Olea europaea; family Oleaceae along with lilacs, jasmine and ash trees), a traditional tree crop of the Mediterranean Basin. The wild olive tree originated in Asia Minor, today the countries of Turkey, Syria, and Lebanon.[1] It is commonly used in cooking, cosmetics, pharmaceuticals, and soaps and as a fuel for traditional oil lamps.





The grades of oil extracted from the olive fruit can be classified as:





Virgin means the oil was produced by the use of physical means and no chemical treatment. The term virgin oil referring to production is different from Virgin Oil on a retail label (see next section).


Refined means that the oil has been chemically treated to neutralize strong tastes (characterized as defects) and neutralize the acid content (free fatty acids). Refined oil is commonly regarded as lower quality than virgin oil; the retail labels extra-virgin olive oil and virgin olive oil cannot contain any refined oil.


Pomace olive oil means oil extracted from the pomace using chemical solvents, mostly hexane, and by heat.


Quantitative analysis can determine the oil's acidity, defined as the percent, measured by weight, of free oleic acid it contains. This is a measure of the oil's chemical degradation; as the oil degrades, more fatty acids are freed from the glycerides, increasing the level of free acidity and thereby increasing rancidity. Another measure of the oil's chemical degradation is the organic peroxide level, which measures the degree to which the oil is oxidized, another cause of rancidity.





In order to classify it by taste, olive oil is subjectively judged by a panel of professional tasters in a blind taste test. This is also called its organoleptic quality.





Olive oil is the main cooking oil in countries surrounding the Mediterranean Sea.





Extra-virgin olive oil is mostly used for salad dressings and foods to be eaten cold. Used cold, its strong flavor is able to stick out while not being compromised by heat. It is also used for sauteing ingredients.





The higher the temperature to which the olive oil is heated, the more one should prefer the use of refined olive oils. When extra-virgin olive oil is heated above 350 掳C (662 掳F), the unrefined particles within the oil get burned. This leads to deteriorated taste and even toxicity[citation needed]. Also, the pronounced taste of extra-virgin olive oil is not a taste most people like to associate with their deep fried foods. Refined olive oils are perfectly suited for deep frying foods and should be replaced after six uses.





Choosing a cold-pressed olive oil can be similar to selecting a wine. The flavor of these oils vary considerably and a particular oil may be more suited for a particular dish. Also, people who like lots of tannins in their red wines might prefer more bitter olive oils.





An important issue which is often not realized in countries that do not produce olive oil is that the freshness makes a big difference. A very fresh oil, as available in an oil producing region, tastes noticeably different from the older oils available elsewhere. In time, oils deteriorate and become stale. One-year old oil may be still pleasant to the taste, but it is surely less fragrant than fresh oil. After the first year olive oil should be used for cooking, not for foods to be eaten cold, like salads.





The taste of the olive oil is influenced by the soil that the olive trees grow on, but also by the moment when the olives have been harvested and ground.





Olive oil has more uses than just consuming, it also works as a natural and safe lubricant. For example, lubricating the machinery that is used within the kitchen (grinders, blenders, cookware, etc.)
Oil refineries. It's mineral oil and some have exotic plant oils and perfumes added.
