Abstract
During the batch treatment of defatted rice bran by subcritical water, the temperature changes with time in order to reach the desired level. The bran was treated with subcritical water at different temperature rates from room temperature to 250°C to obtain extracts, and the properties of the extracts were examined. The extract yield was higher at higher temperature rates. UV-Visabsorption and high-performance liquid chromatography analyses indicated that the rate affected the substances contained in the extracts. However, the antioxidative ability of the extract versus the oxidation of linoleic acid only slightly depended on the rate. Therefore, a fast temperature increase to the desired level is favorable for high yield and short treatment time.
