摘要
为了优化微波辅助法萃取马齿苋多糖工艺,采用单因素试验和正交试验优化工艺条件研究了液料比、微波处理时间、微波功率对马齿苋多糖萃取率的影响。结果表明:微波辅助法萃取马齿苋多糖最佳工艺条件为液料比35∶1(mL∶g),微波处理时间15min,微波功率540W,此时萃取率为11.69%。与水提法相比(40min,萃取率8.69%),微波辅助提取法节省了萃取时间,提高了萃取率。
In order to optimize the microwave-assisted extraction process of polysaccharide from P.oleracea,a single-factor test and an orthogonal test were conducted to explore the effects of liquid-solid ratio,microwave processing time and microwave power on the polysaccharide extraction rate.The results showed that the optimum conditions for microwave-assisted extraction of polysaccharide from P.oleracea were as follows： liquid-solid ratio 35∶1（mL∶g）,microwave processing time 15 min and microwave power 540 W.The extraction rate could be up to 11.69% under these conditions.Compared with water extraction,microwave-assisted extraction saved extraction time（40 min） and improved the extraction rate（8.69%）.
