| Abstract:The solvent extracted crude rice bran oil contained many knids of gum impurities,which badly influenced the refining effenct of the oil.Proper degumming method should be chosen to remove the gum impurities.The oxalic acid degumming process,the production effect and its influence on the following procedure were described.The results showed that the refined rice bran oil with stable quality and light color could be produced through a series of oxalic acid degumming,bleaching,dewaxing and physical refining |
