菊芋中菊粉提取工艺的研究

Study on Extraction Process of Inulin from Helianthus tuberosus

摘要:

本文采用微波辅助提取、热水浸提法从菊芋中提菊粉，从而筛选出最好的提取方法。通过单因素和正交试验确定最佳的菊粉提取工艺。试验结果表明，最佳微波辅助提取工艺为：料液比1:18，微波处理时间6 min，微波功率450 W。菊粉得率达12.2%。

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%.
