چکیده

The high oil content of the avocado fruit (Persea americana Mill.) has been known since Aztec times, with the fruit sometimes referred to as “vegetable butter” or “butter pear.” The plant originated in Central America, and its cultivation has spread to warm subtropical and temperate climates worldwide. The flesh of an avocado can contain up to 30% oil (based on fresh weight), but there is very little in the seed (≅2%) or the skin (≅7%). Avocado oil was originally, and still is, extracted for cosmetic use because of its very high skin penetration and rapid absorption. Following pre-drying of the avocado flesh to remove as much water as possible (≅65% water in avocado flesh), avocado oil for cosmetics is traditionally extracted with solvents at elevated temperatures. After extraction, the oil for application in skin care products is usually refined, bleached, and deodorized, resulting in an odorless yellow oil.
