Specifications

 
Corn oil (maize oil) is oil extracted from corn (maize). Its high smoke point makes it an excellent frying oil.

Almost all corn oil is expeller pressed, then solvent extracted using hexane or *-methylpentane (isohexane). 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 acids and removes color (bleaching). Corn oil specifications:
