However, coix seeds collected in a natural state can only be obtained as crude coix seed oil after simple grinding and distillation. In order to improve the purity and quality of coix seed oil, it is necessary to further refine and extract coix seed oil so that it can be used in food, health products and cosmetics.

[0003] Common methods of refining coix seed oil usually use alkali refining and distillation refining. Alkali refining is to react coix seed oil with an alkali solution of a certain concentration, and then it will undergo deacidification, cooling, separation, decolorization and deodorization to obtain refined coix seed oil. However, in the refining process, each part is carried out almost independently, especially deacidification and decolorization, which require water and water volatile substances to be treated, but in many cases they are provided separately.
