First stage of refining is to remove Free Fatty Acids (F.F.A.) with caustic soda treatment called Neutralizing Process, thereafter further processed in the bleaching section under vacuum & treated with bleaching earth & activated carbon for removing colour. Finally it will be deodorized under high vacuum and high temperature to remove the odour from the oil.
The edible oil obtained in a batch refining is of good quality meeting all requirement of International standard. However, in case of Sunflower and Rice Bran Oil, there is one more process of De- Waxing after bleaching process.
The refining of FATS and OILS is comprised of Degumming, Alkali refining and Water Wash. There are few choices to choose, short / long mixed process with Degumming or GUM Conditioning.
FATS and OILS containing gums and FFA (Free Fatty Acid) are required to be removed by refining process for producing quality refined oil.
