| Abstract: | The processing technologies were examined for their efficiency in production of dietary fiber from rice bran and wheat bran.The optimal parameters were as follows:for water hemicellulose of rice bran: rice bran solvent ratio 1∶10,at 60℃ for 3h,extraction rates 1.38%;for alkaline hemicellulose of rice bran: rice bran solvent ratio 1∶10,alkaline concentration 0.5% at 25℃ for 4h,extraction rates 8.86%;for dietary fiber of wheat bran : α amylase addition 0 4%,alkaline concentration 0 6% at 70℃ for 90 min,extraction rates 66 27%. |
