Abstract | The main objective of this study was to improve the extractability and quality of rice bran oil using different mixturesof ethanol (Eth) and hexane (He). Eth/He ratios of 0:100, 20:80, 40:60, 60:40, 80:20, and 100:0 (%v/v) were used for theextraction. The ultrasound extraction processes were experimented at 2.5 W/g, 30 ยฐC for 15 min. The results indicated that thehighest oil extractability was found in the 60:40 (%v/v) Eth/He mixture. Experimental results also showed that the mixture of60:40 (%v/v) Eth/He had significant effect on the physiochemical properties and phytochemical content of crude rice bran oil(p<0.05). Especially, the crude rice bran oil was low in peroxide value (3.03 meqO2/kg oil) and acid value (2.01 mg KOH/g oil),high in iodine value (105.00 mg I2/100g oil), and lighter in color. Further analysis revealed that oleic, linoleic, and palmitic acidswere the dominant fatty acids in the Eth/He extracted oils. |
