中文摘要: 在常规糖化工艺基础上,添加纤维素酶辅助粉葛的糖化。采用单因素试验、正交试验优化得到纤维素酶解 的最优工艺条件为:纤维素酶用量为 0.6 %,酶解温度为 55 ℃,酶解时间为 60 min,最终糖化液的还原糖含量为 8.312 g/100 mL,未加纤维素酶处理的糖化液还原糖含量为 7.385 g/100 mL,说明纤维素酶处理能够改善粉葛糖化 的效果。

Abstract:On the basis of common saccharification process, the saccharification conditions of kudzu was stud- ied by adding cellulase. Using the single factor tests and orthogonal tests, the optimum saccharification condi- tions were obtained. The kudzu was hydrolyzed by adding 0.6 % cellulase to react at 55 ℃ for 60 min. The con tent of reducing sugar of saccharification liquid was 8.312 g/100 mL, while that of the blank test was 7.385 g/100 mL. The results showed that adding cellulase could improve the effect of kudzu saccharification.
