Olive Oil: An oil obtained solely from the olive and excludes any oil extracted from olives by solvents, re-esterification processes or any mixture with oils of other kinds. There are three types of olive oil: virgin, refined and olive oil or pure olive oil.
Virgin Olive Oil
: Around 10% of the olive oil produced in the world is top quality virgin olive oil. It is the oil obtained from the fruit of the olive tree solely by mechanical or other physical means under conditions, particularly thermal conditions, that do no t lead to alterations in the oil, and which has not undergone any treatment other than washing, decantation, centrifugation and filtration. The terms "extra", "fine", and "ordinary" or "semi-fine" are used to describe virgin oil.
Extra Virgin
: This is the top grade. Free of taste defects, it also must not have an oleic acidity greater than 1% by weight (1 gram per 100 grams).
Fine
: Also called virgin olive oil. While still perfect in aroma, flavor, and color, it can have an acidity level no greater than 2% by weight.
Ordinary/Semi-Fine
: Also called virgin olive oil semi-fine, virgin olive oil ordinary, "corriente", or "semifino". Good taste and aroma. It is allowed an acidity of 3.3%.
(virgin oil not for human consumption is termed "lamp oil" and is destined for refining)
Refined Olive Oil
: Oil obtained from virgin olive oil by refining methods. In the refining process, caustic soda (lye) is used to purify, decolorize, and deodorize the oil. It is also extracted from olive pomace (residue left) after the majority of the oil has been extracted in the "virgin" process. Many times refined oils can be the product of damaged olives or culls from a pickling operation.
Pure Olive Oil
: A blending of refined and virgin olive oils to obtain the uniformity of taste and color desired by the consumer. Most imported brands sold in the United States are "pure" or "100% pure" olive oils. |
