Among stored rice hulls at 37°C and non-stored rice hull, total phenolic content ranged from 14.6417± 0.0154 to 20.1195 ± 0.3284 mg/g, with the lower values coming from the 7 month stored rice hull at 37°C, while the higher values were from non-stored rice hull (Table 2). The results also showed stored rice at 37°C had lower total phenolic contents than non-stored rice hull. The total antioxidant capacity was measured using the DPPH assay and converted to EC50. It was EC50 0.0392, among the non-stored rice hull (Table 2). Among the stored rice at 37°C, the mean EC50 was 0.3776, ranging from 0.3397 to 0.4091. The lipid peroxidation was measured using the linoleic acid autoxidation and converted to EC50. It was EC50 0.1150, among the non-stored rice hull. Among the stored rice at 37°C, the mean EC50 was 0.5996, ranging from 0.405 to 0.7745.
