Title: Refinement of crude edible oil
Inventor: KON YOSHIMITSU
IPC: C11B3/04
Filed: 1993-12-30
Abstract: PURPOSE:To refine a crude edible oil economically advantageously by simply and effectively reducing the amount of the adsorbent used in a decolorization step by adding sulfuric acid and phosphoric acid to a crude edible vegetable oil and simultaneously effecting the separation of soap and the removal of a chlorophyll pigment in an alkali refining step. CONSTITUTION:This refinement process comprises adding a combination of sulfuric acid with phosphoric acid as the acid used in the acid treatment in a step of refining a crude edible vegetable oil with an aqueous alkali solution, and simultaneously effecting the separation of soap and the removal of a chlorophyll pigment in the alkali refinement step.When sulfuric acid alone is used as the acid, the formed soap is small in particle size and is light, therefore can be insufficiently separated and is apt to be emulsified in the subsequent step of water washing, which causes poor workability. When a combination of sulfuric acid with phosphoric acid is used as the acid, the soap grows in K large particle size and can be separated in markedly improved workability.
