摘要
通过单因素实验,将用紫外分光光度计在355 nm处测定的提取液吸光度作为实验指标,确定超声波提取花生壳中黄色素的最佳条件为:以70%乙醇作提取溶剂、料液比为1 g∶9 mL、超声波频率为20 kHz、每次提取8 min、提取2次,色素粗品收率为4.3%。与加热回流法、浸泡法比较,超声波提取方法具有效率高、时间短、节省能源等优点。
Ultrasound wave was applied during the extraction of yell＇ow pigment from peanut shell. The optimum processing conditions were as follow：the mass ratio of solid and solvent was 1： 9,the solvent was 70% ethanol solution,the peanut shell was extracted 8 min for twice. Less time,energy saved and high extraction efficiency could be obtained by this way as compared with normal methods.
