摘　　要：采用超声波辅助热水浸提法提取菊芋中的菊糖。结果表明,相比于热水浸提法,采用超声波辅助法可以将菊糖的提取率提高28.73%,效果显著。通过单因素试验和正交试验得到最佳提取条件为超声波输出功率112 W、超声波提取时间25 min、料液比1∶15,水浴提取温度100℃。在此条件下菊糖的提取率可达到70.05%。影响因素从大到小依次为:水浴提取温度>超声波输出功率>料液比>超声波提取时间。Inulin was extracted from Jerusalem artichoke by uhrosonic-assisted hot water extraction method. Compared with hot water extraction, inulin extraction yield can be increased by 16.70% through uhrosonic assisted method, and the effect is remarkable. It was concluded from single factor experiment and orthogonal mothod that the optimal condition of extraction was uitrosonic treatment for 25 rain at the power of 112 W before marinated at 100℃,the mass ratio of material to water being 1：15. Under this condition, the extraction rate was 70.05%. The orthogonal factors affecting ranked ： water bath extraction temperature〉uhrosonic extraction power〉ratio of material to water〉uhrosonic extraction time.
