Abstract

The utilization of rice bran in rice milling in Java, in general, is not as soon as after leaving the mill. The research aims to determine whether the duration of rice bran storage affects the antioxidant activity, yield and total phenols of hydrophilic extracts. The study was conducted with rice bran treatment stored for 0, 1, and 2 weeks. Each sample was extracted hydrophilic component with ethanol solvent. The extracts obtained were tested including yield, total phenol, and antioxidant activity. The results showed that the increase in yield experienced a significant difference, especially in the second week. Total phenol and antioxidant activity increased significantly in the first week and decreased again in the second week. The conclusions from this study indicate that the duration of rice bran storage needs to be considered the optimal limit.

Keywords: antioxidant activity, hydrophilic extracts, rice bran, total phenols, yield
