This study examined the extraction of bran rice oil using supercritical carbon dioxide. Free fatty acids contained in bran rice were stabilized at 5.25% for 8 months by fluid bed dryer equipment. Supercritical carbon dioxide extraction of rice bran oil at pressure of 400 bar, temperature of 60 o C, CO 2 flow rate of 20 g/min for 120 minutes yielded 14.84% oil. The concentration of γ-oryzanol in rice bran oil extracted by supercritical carbon dioxide (0.50%) was higher than in rice bran oil derived from hexane Soxhlet extraction (0.42%). The effect of pressure and temperature on extraction yield and the concentration of γ-oryzanol contained in rice bran oil was observed. Keywords Rice bran, rice bran oil, γ-oryzanol, free fatty acid, supercritical carbon dioxide. References [1] A. A. Wani, P. Singh, M. A. Shah, U. S. Weisz, K. Gul, I. A.
