摘要
为优化黑玉米多糖的超声辅助酶提取工艺,应用小组合试验设计,采用响应面法对提取工艺条件进行优化,确定黑玉米粗多糖超声辅助酶提取工艺的最佳条件:超声作用时间33 min,提取温度59℃,纤维素酶添加量1.23%,中性蛋白酶添加量0.93%,在此条件下多糖得率达46.01%,所建立的数学回归模型能够较准确预测黑玉米多糖的得率。
To optimize the extraction process of black corn polysaccharide,small composite design and response surface analysis were applied to optimize extraction condition.The optimal technological conditions can be concluded as follows：33 min at 59℃,cellulase dosage 1.23%,neutral protein enzyme dosage 0.93%.On these conditions,the yield of polysaccharide is up to 46.01%,and the established regression mathematical model can predict black corn polysaccharide yield accurately.
