| 摘 要： | 本文介绍了椰壳常压酸水解制备木糖工艺过程,通过正交试验考察了酸预处理时间、酸浓度、椰壳粉粒度、水解时间等对木糖产率的影响。结果表明:酸浓度与水解时间对木糖产率有显著性影响,酸预处理时间和椰壳粉粒度对木糖产率没有显著性影响,采用0.2mol/L的盐酸,100℃温度下水解6h,木糖产率可达椰壳空气干燥基质量的16%,水解液经脱色脱盐等一系列工艺制备的椰壳木糖纯度达99%以上。

| Abstract: | In this paper, xylose was prepared from coconut shell by normal pressure acid hydrolysis processes. The effects of pretreatment time, acid concentration, reaction time and granularity on xylose yield were investigated by means of orthogonal test. It was indicated that the xylose yield could reach up to 16% with purity of 99% under optimal conditions of 0.2mol/L HCl and at 100℃ for 6h. Acid concentration and reaction time had significant effect on xylose yield, whereas pretreatment time and granularity had little effect on xylose yield. |
