| 摘 要： | 通过正交试验,研究了超声波功率、提取温度、提取时间、料液比和提取液pH值对木枣多糖得率的影响。结果表明,各因素影响程度依次为:提取液pH值>料液比>提取时间>提取温度>超声波功率;得到最佳工艺参数为:超声波功率为200W,料液pH值为9,料液比为1∶12,温度为50℃,提取时间为15min。在此参数条件下,木枣多糖提取得率为1.81%。

| Abstract: | In this paper,the factors of ultrasonic power,extracting temperature,extracting time,solid liquid ratio and pH were studied. The results indicated that the most significant factor was the pH,then solid liquid ratio,extracting time, extracting temperature,and ultrasonic power. The optimal conditions in the extraction procession were as follow:ultrasonic power 200 W,pH 9,solid-liquid ratio 1∶12,extracting temperature 50 ℃,extracting time 15 min. On the optimal conditions the obtaining rate of polysaccharides could reach 1.81%. |
