ABSTRACT
A by-product of rice bran oil and protein production was treated with water and compressed hot water at 20 degrees C to 260 degrees C for 5 min, and at 200 degrees C and 260 degrees C for 5 to 120 min. Each extract was evaluated for its yield, radical scavenging activity, carbohydrate, protein, total phenolic and furfural contents, molecular-mass distribution and antioxidative activity. The maximum yield was obtained at 200 degrees C. The radical scavenging activity and the protein, total phenolic and furfural contents of the extract increased with increasing temperature. However, the carbohydrate content abruptly decreased when treated at above 200 degrees C. The extract treated at 260 degrees C for 5 min exhibited suppressive activity toward the autoxidation of linoleic acid. Each extract obtained at temperatures lower than or equal to 200 degrees C exhibited emulsifying ability.
