Abstract
The utilization of rice bran on the rice mills in Java, in general, is not taken immediately after coming out of the mill. This study aims to determine the effect of storage time of bran to the yield, total phenol and antioxidant activity of the extract hydrophilic. Total phenolic content of hydrophilic bran extracts analyzed using the Folin-Ciocalteu method while testing the antioxidant activity using DPPH free radical fishing methods (2.2 diphenyl-1-picrylhydrazyl). Storage time in this study conducted over four weeks. Each sample was extracted with ethanol hydrophilic components. The hydrophilic extract was analyzed yield, total phenol, and antioxidant activity. The results showed that in the first week of storage bran has the highest total phenol (498.8467 EAG mg / g) and the highest antioxidant activity (80.7825%). While in the fourth week of storage has the highest yield (11.2575%). The higher the value of total phenols hydrophilic extract of bran in the first week, the higher the ability to inhibit free radicals.
