摘要：
The effects of mashing variables, such as mashing-in time, mash thickness, grist coarseness, and stirring, on the solubilization and hydrolysis of arabinoxylans were studied. Response surface methodology (RSM) and central composite design (CCD) were employed to further optimize the process. Under the optimum operational conditions, namely mashing-in temperature of 49 degreesC, first saccharification rest temperature of 62 degreesC and second saccharification rest temperature of 71 degreesC, arabinoxylan content decreased from 1510 to 1170 mg/l.
