Soybean oil (British English: soyabean oil) is a vegetable oil extracted from the seeds of the soybean (Glycine max). It is one of the most widely consumed cooking oils and the second most consumed vegetable oil. [2] As a drying oil, processed soybean oil is also used as a base for printing inks and oil paints.
The origin of soy bean cultivation remains scientifically debated. The closest living relative of the soybean is Glycine soja (previously called G. ussuriensis), a legume native to central China. [55] There is evidence for soybean domestication between 7000 and 6600 BC in China, between 5000 and 3000 BC in Japan and 1000 BC in Korea. [56]
Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). [1] The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides. Alkali treatment also neutralizes free fatty ...
The processing of vegetable oil in commercial applications is commonly done by chemical extraction, using solvent extracts, which produces higher yields and is quicker and less expensive. The most common solvent is petroleum-derived hexane. This technique is used for most of the "newer" industrial oils such as soybean and corn oils.
