摘要:

为提高酵母多糖提取率,对其提取过程进行优化。在单因素试验的基础上,利用中心组合试验设计原理,以高压时间、超声功率和超声时间为试验因素,以多糖提取率为响应值,采用3因素3水平的响应面分析法建立数学模型,获得最佳提取工艺。通过二次回归模型响应面分析得出酵母多糖提取的最佳工艺条件为高压时间35min、超声功率510W、超声时间26min;在此条件下,多糖提取率的预测值为29.82%,验证值为29.84%。证明采用响应面法对酵母多糖提取条件进行优化,方法可行,可用于实际操作与实验预测。

Abstract:

Response surface methodology was used to optimize polysaccharide extraction from yeast to enhance polysaccharide yield. Polysaccharide yield was investigated with respect to high pressure treatment time, ultrasonic power and ultrasonic treatment time. A quadratic regression model was established based on a three-variable, three-level Box-Behnken design. The optimum conditions of high pressure treatment time, ultrasonic power and ultrasonic treatment time were found to be 35 min, 510 W and 26 min, respectively. Under these conditions, the predicted value of polysaccharide yield was 29.82%, whereas the actual value was 29.84%. Thus, the optimized extraction procedure is feasible for practical operation and experimental prediction.

Key words: yeast polysaccharide, response surface methodology, extraction, optimization
