How does refining affect the quality of cooking oil?

Crude cooking oil contains impurities, which not only affect the edible value and safe storage of oil, but also bring difficulties to deep processing. Therefore, crude cooking oil is usually refined to remove impurities and improve the quality and flavor of cooking oil.

Refining cooking oil

In the cooking oil refining process, not all the "impurities" in the oil are removed, but the impurities harmful to food, storage, and industrial production will be removed, such as gossypol, protein, phospholipid, mucus, and water, etc. , while beneficial "impurities" such as vitamin E and sterols are retained. Therefore, according to different requirements and uses, the purpose of cooking oil refining is to remove unnecessary and harmful impurities in oil and obtain finished oil that meets certain quality standards.

Cooking oil refining usually includes four steps of degumming, deacidification, decolorization and deodorization. Each step deals with the "impurities" of the cooking oil. The following is a detailed introduction for you:
