Producing quality edible oil from Rice Bran is one of the most challenging amongst all edible oils. Rice bran (RB) needs to be processed immediately after it is milled in rice mills; otherwise, the amount of Free Fatty Acids (FFA) in the oil starts rising.
RBO is extracted from rice bran using Solvent extraction (food-grade Hexane is used as a solvent). After extraction, the process of refining this crude oil into nutrient-rich and healthy edible oil requires a highly controlled and tightly monitored environment. This is because of the presence of very high amounts of by-products like gums, waxes and free fatty acids in crude RBO.
