Abstract:This study analyzed the effect of microwave treatment technology on the acid value of rice bran from microwave treatment temperature，microwave frequency，and rice bran spreading thickness with acid value as the evaluation index by single-factor and orthogonal experiments.The orthogonal test results indicated that the influence of various factors was as follows：microwave action frequency>microwave treatment temperature>paving thickness.The storage test showed that the microwave treatment temperature of 95 ℃，microwave action frequency of 6 Hz and coating thickness of 3 cm had the best effect on the treatment of rice bran.Under this condition，the price of rice furoic acid increased slowly，and the price of rice furoic acid was less than 25 mg/g after 4 weeks of storage.
