摘要
以麦胚为原料,蒸馏水为提取溶剂,采用超声波辅助提取法提取麦胚多糖,通过单因素和正交试验研究了料液比、提取温度、提取时间、超声波功率对麦胚多糖提取率的影响。结果表明,麦胚多糖的最佳提取工艺条件为:料液比1∶13,提取温度65℃,提取时间40min,超声波功率300W,在此工艺条件下麦胚多糖的提取率为92.33%,极显著高于同条件下非超声波辅助提取的多糖提取率(38.70%)。
Polysaccharide was extracted from defatted wheat germ with water as extracting agent by ultrasonic-assisted method. The effects of solid-liquid ratio, ultrasonic extracting temperature and time, ultrasonic power on the polysaccharide extraction rate were studied, and the optimum extraction parameters were confirmed through the single factor and orthogonal experiments. The results showed that the optimum solid-liquid ratio was 1 ： 13 （m/V）, extraction temperature was 65 ℃ ,extraction time was 40 min, and ultrasonic power was 300 W. Under this optimum condition, the extraction rate of polysaccharide was 92. 33%, significantly higher than that without ultrasonic （38.70%）.
