响应面法优化微波提取玫瑰茄花色苷工艺研究

摘要

采用响应面法优化微波提取玫瑰茄花色苷工艺，在单因素实验基础上，以微波功率、料液比、提取时间为自变量，设计三因素三水平响应面实验，以花色苷含量为响应值进行响应面优化。结果表明，影响花色苷提取效果的3个因素其影响大小依次为料液比＞微波功率＞提取时间，最佳工艺条件为微波功率164 W，料液比1∶25，提取时间12 min，利用此工艺参数得到的花色苷含量为537．873 mg／100 g。%The microwave extraction of anthocyanins from roselle was optimized.Based on single factor tests,taking microwave power,ratio of material to liquid and extraction time as independent variable,the response surface experiment,which includes 3 factors and 3 levels,was designed with the content of an-thocyanins as response value.The result showed that the effects of three factors on extraction of anthocya-nins were ratio of material to liquid >microwave power >extraction time.The optimum processing condi-tions were microwave power 164 W,ratio of material to liquid 1∶25,and extraction time 12 min.The an-thocyanins content could reach 537.873 mg/100 g material.
