Continuous Chemical Refining Plant
The process of refining reduces the free fatty acid, phospholipids,
carbohydrates, or proteins. The most widely practiced form
of refining method is an alkali treatment. By treatment
of the fats and oils with an alkali solution, the free fatty
acid converts into water soluble soaps. Phospholipids carbohydrates
and proteins also can be changed to water soluble substances
with hydration. After
the alkali treatment, the fats and oils are washed with
water to remove residual water soluble soaps.
