Abstract
The quality characteristic properties of rice bran extracts from a range of cultivars (i.e., Bukkyeong 2012-2, Hanahreum, and Jasmin 85) that had been prepared using different extraction methods (i.e., supercritical fluid or hexane) were investigated. The pH values of the hexane rice bran extracts were higher than those of the supercritical fluid extracts, while the L values, a values, and b values were found to be 43.70-56.51, -1.73-0.80, and -0.08-9.97, respectively. In addition, the iodine values of the supercritical fluid rice bran extracts (58.46-59.30 g) were higher than those of the hexane extracts (41.30-42.80 g), while the acid values of the Jasmin 85 cultivars obtained from the supercritical fluid and hexane rice bran extracts were 23.66 and 2.15 mg/g, respectively, which were lower values than those obtained for the other extracts. Furthermore, the peroxide values of the bran extracts were 3.33-70.06 meq/kg, where the values obtained for the supercritical fluid rice bran extracts (44.71-70.06 meq/kg) were higher than those of the hexane extracts (3.33-35.67 meq/kg). In the case of the TBA value, the supercritical fluid rice bran extracts gave higher values (68.23-124.55 mg/kg) than the hexane extracts (5.33-97.16 mg/kg). Moreover, the total tocopherol contents of the supercritical fluid and hexane rice bran extracts were 10.20 and 10.63 g/100 g for the Bukkyeong 2012-2 cultivar, 8.30 and 7.35 g/100 g for the Hanahreum cultivar, and 4.85 and 6.94 g/100 g for the Jasmin 85 cultivar. The fatty acid contents of the rice bran extracts decreased in the order of oleic acid, linoleic acid, then palmitic acid, and the unsaturated fatty acid contents of the Hanahreum rice bran extracts (81.21 and 80.60%) were higher than those of the Bukkyeong 2012-2 and Jasmin 85 rice bran extracts. Our results therefore indicate that the quality characteristics of the supercritical fluid Bukkyeong 2012-2 and Hanahreum rice bran extracts render them useful for application in the food industry.
