采用黑曲霉和WO3/SnO2固体酸联合水解花生壳制备糠醛,运用正交实验和响应面分析方法对主要因素进行了优化分析。酶解的正交实验结果显示:在原料粒度110目、固液比1:10、酶解温度为50℃、酶解时间为7h和酶液用量为30U/g干花生壳粉的条件下,制备戊糖的平均含量为14.87g·L~(-1)。固体酸制备糠醛的响应面分析表明:当水解温度为163℃,水解时间134min,固体酸用量为6.4%时,糠醛的得率为68.52%,与未采用黑曲霉水解的工艺相比,糠醛的得率提高了15.69%。

Furfural was made from peanut hull powder with synergistic hydrolysis with aspergillus niger and solid acid,orthogonal experiment and response surface methodology were applied to carry out optimum analysis on main parameters.The orthogonal experiment of enzyme experiments result showed that when the raw material granularity was 110 grit,solid-liquid ratio was 1：10,the reaction temperature was 50°C,the reaction time was 7h,the volume of the enzymolysis solution was 30U/g of dried peanut hull powder and the average content of pentose was 14.87g...
