摘要:

研究野生阳荷水溶性膳食纤维的最佳提取工艺,以提取时间、料液比、微波功率和浸提液pH值为影响因素,进行四因素三水平的响应面试验设计,对其提取工艺条件进行优化,结果表明:最佳提取工艺条件为提取时间151.4 s、料液比1∶33(g/mL)、微波功率264 W、浸提液pH 3.65,此条件下水溶性膳食纤维的提取率为5.52%,与理论值5.75%相差较小。由此可知,响应面法优化微波辅助提取阳荷水溶性膳食纤维具有时间短、能耗低、提取率高等特点。

Abstract:

The microwave-assisted extraction of water-soluble dietary fiber (SDF) from Zingiber striolatum Diels fruits
was optimized by response surface methodology. An experimental design was carried out involving four variables at three
levels each. An extraction time of 151.4 s with a microwave power of 264 W using sulphuric acid solution at pH 3.65 as
the extraction solvent with a solid-to-solvent ratio of 1:33 (g/mL) was found to be optimal. Experiments carried out under
the optimized conditions resulted in an extraction yield of 5.52%, agreeing with the predicted value (5.75%). The extraction
procedure presented in this study is characterized by time saving, low energy consumption and high extraction efficiency.

Key words: wild Zingiber striolatum Diels, water-soluble dietary fiber, microwave-assisted extraction, response surface methodology
