Percentage losses or gains for DPPH, FRAP, TPC and TFC of rice bran, rice husk and ground rice husk by different treatments compared to raw samples are shown in Table 1. The increased values of TPC and FRAP as affected by FIR accounted for approximately 15% and 20% in rice bran, 96% and 35% in rice husk, and 87% and 10% in ground rice husk. While both TPC and FRAP values were increased less than 10% by hot air drying method. In addition, TPC was
increased approximately 10% in rice husk and 30% in ground rice husk. In contrast, TPC was decreased by cellulase treatment in rice bran.
