The alkali refined rice bran oil (ARBO) and the esterified rice bran oil (ERBO) with glycerol were analyzed for their physicochemical characteristics and the compositions. Specific gravity, refractive index and yellowness of ERBO was higher than ARBO but smoking point was 60-80 deg. C higher than ERBO. The free fatty acid content was 0.05% ARBO and 0.88-1.36% ERBO. The wax was not detected in ARBO but the soft and hard waxes were detected in ERBO. The lipids were composed of 98-99% neutral lipid, 0.2-0.5% glycolipid and 0.1-0.5% of phospholipid in all samples
