Cooking oil refining process :

1. Degumming and deacidification
Degumming is using phosphoric acid ,water to react crude oil and then separate phosphatide from oil. But in order to reduce more phosphatide, after enough phosphoric acid treatment, adding alkali inside oil to neutralize free fatty acid , and washing before gum separation , this process is called deacidification. Here the byproduct is soap stock which can be used for making soap.
