摘要
以甜叶菊为基本原料,对甜叶菊中的甜菊糖苷的提取工艺条件进行优化,以提高甜菊糖苷的提取率,同时确定纤维素酶对甜菊糖苷提取率的影响。依据单因素和正交试验得出了获得最高甜菊糖苷提取率的条件是:纤维素酶质量浓度0.2%,提取温度50℃,提取时间90min,溶液pH为5,该条件下的提取率为13.98%,比优化前高出了1.94%。
In order to improve the extraction yield of stevioside and determine the effect of cellulase for the extraction yield of stevioside,this paper optimized the stevioside extraction conditions with Stevia as the basic raw material.Based on the single factor and orthogonal test,we got the optimal conditions that cellulase enzyme concentration was 0.2%,and extracted 90min at temperature 50℃ under pH 5.The extraction rate of stevioside was 13.98% under the optimal conditions,1.94% higher than before the optimization.
