In the refining process, according to the type of oil, the wax in the oil is sometimes removed, so that the finished oil is more transparent and avoids the turbidity caused by wax precipitation after a period of storage.

The process of oil degumming can produce phospholipid, which is a high value-added product and can be used as emulsifier and stabilizer in many foods.

Some oil refineries also separate fats according to the melting point of fatty acids. Palm oil producers, for example, often divide palm oil into palm stearin which has a higher melting point, and palm soft fat which has a lower melting point. The former is solid at room temperature, and the latter is liquid at room temperature, so that it can meet the needs of more different processing scenarios.

3. Food safety needs

The refining process removes harmful impurities and toxins from raw materials, making refined oils generally safer. Cottonseed oil is a case: cottonseed oil contains gossypol, which is reproductive toxic and therefore must be refined to make refined cottonseed oil that is safe to eat.
