  5. Corn oil - Wikipedia

    en.wikipedia.org/wiki/Corn_oil

    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 ...

    en.wikipedia.org/wiki/Dewatering_screw_press

    Oil expellers are used to squeeze the fat out of soybeans, peanuts, sunflower seeds, canola (rape seeds), and other oil seeds. The expeller works by exerting extremely high pressures which convert the fat in seeds into a liquid oil. Once the oil is liquefied the oil flows through the screen and is collected.
