Olive Oil Virgin Refined
Virgin olive oil comes from virgin oil production only, has an acidity less than 2%, and is judged to have a good taste. Refined olive oil is the olive oil obtained from virgin olive oils by refining methods which do not lead to alterations in the initial glyceridic structure. It has a free acidity, expressed as oleic acid, of not more than 0.3 grams per 100 grams (0.3%) and its other characteristics correspond to those fixed for this category in this standard. This is obtained by refining virgin olive oils which have a high acidity level and/or organoleptic defects which are eliminated after refining. Over 50% of the oil produced in the Mediterranean area is of such poor quality that it must be refined to produce an edible product. Note that no solvents have been used to extract the oil but it has been refined with the use of charcoal and other chemical and physical filters. An obsolete equivalent is "pure olive oil" Olive oil is a fruit oil obtained from the olive (Olea europaea; family Oleaceae), a traditional tree crop of the Mediterranean Basin. The wild olive tree originated in Asia Minor and spread from there as far as southern Africa, Australia, Japan and China. It is commonly used in cooking, cosmetics, pharmaceuticals, and soaps and as a fuel for traditional oil lamps. Olive oil is used throughout the world, but especially in the Mediterranean.
