The crude oil degumming process is a phospholipid contained in the gum to be removed in the process, which is a total of chemical refining and the physical refining process. Is the use of phospholipids to produce fluff swelling and oil separated from the oil but containing non-hydratable phosphatide, and therefore in the production of as much as possible in order to remove phospholipids, usually by acid degumming, acid degumming process is mainly phosphoric acid and citric effective contact with the phospholipids contained in the hair oil, will not be de-hydration hydration degumming process unless converted into hydrated phospholipid phospholipid; another enzymatic degumming, the principle is the use of non-hydration phospholipase phospholipids converted to hydrated phospholipids, it becomes easier to separate the removal, taking into account the continuity of the price and production of enzymes, currently the method has not yet put into large-scale production; membrane separation method, the principle use of ultrafiltration membranes to remove the leaching mixed phospholipids in oil method, but since the film cost reasons and proof countermeasures, has not been able to have practical applications.

Recently, studies have shown that the use of hydrophobic poly phthalic imide composite membrane, in the absence of solvent system for corn oil degumming experiments, the first membrane filtration, phospholipid concentration can significantly reduce, and possibly up to three months long continuous treatment, but has further improved the practical flow rate of oil filtration problems.
