摘　　要：利用微波辅助提取法对蚕沙中叶绿素进行提取工艺的研究。在单因素试验的基础上通过正交试验优选出最佳微波辅助提取工艺条件为微波萃取剂40%乙醇溶液、微波辐射时间50s、提取时间50min、提取温度70℃。在此条件下叶绿素的提取率可达2.684mg/g,与传统有机溶剂法相比,提取率提高了3.4倍。该方法具有收率高、污染小、能耗低等优点。Microwave was used for extraction of chlorophyll from silkworm feces. The extraction conditions were optimized by orthogonal test on the basis of single factor test. The results showed that the optimal extraction conditions are as follows: taking 40% ethanol as extractant, microwave irradiation time 50 s, extraction time 50 min and extraction temperature 70 ℃. Under these conditions, the extraction rate of chlorophyll is 2.684 mg/g, which is increased by 3.4 times compared with traditional organic solvent e...
