Description
A yellowish, nondrying oil pressed from peanuts, a legume of the species Arachis, such as Arachis hypogaea. Peanuts are native to Brazil; they were brought to Africa, then to the United States and are now cultivated in many countries. Peanut oil contains fatty acids, such as oleic (52-62%), linoleic (21-25%) palmitic (~8%), stearic (~3%), arachidic, and lignoceric. Peanut oil has a nutty taste and odor. It is used in food products, soaps, lubricants, varnishes, and pharmaceuticals.
