Abstract:Inulin of Helianthus tuberosus were extracted via microwave and hot water extraction method, respectively. The microwave extraction was testified the better method by using the single factor and orthogonal experiments and the optimization conditions were showed as follows: the ratio of solid to liquid 1:18, extracted time 6 minutes and microwave power 450 W. Under the optimum conditions, Inulin rate reached 12.2%.
