1.Degumming, water washing,dephosphorization and drying.
Through adding concentration 85% food grade phosphoric acid(amount is 0.3-0.5% crude oil) and hot water to remove hydratable phospholipids and nonhydratable phospholipids.Then add caustic soda to neutralize free fatty acid to decrease acid value.
