摘要
采用L9(34)的正交试验设计,系统研究微波提取黑木耳多酚化合物的工艺条件。以微波功率、微波作用时间、料液比和乙醇体积分数为主要考虑因素,确定了黑木耳多酚化合物微波提取的最佳提取条件为微波作用功率450W、微波作用时间120s、料液比1:25、浸提剂乙醇体积分数75%,此条件下的提取率为0.72%。
The optimal microwave-assisted extraction processing of total polyphenols from Auricularia auricula was investigated by orthogonal experiments to explore the effects of microwave power, microwave treatment time, material-liquid ratio and ethanol concentration on extraction rate of total polyphenols. Results indicated that the optimal extraction processing parameters for total polyphenols from Auricularia auricula were microwave irradiation power of 450 W, microwave treatment time of 120 s, material-liquid ratio of 1：25 and ethanol concentration of 75%. The extraction rate of total polyphenols was up to 0.72% under the optimal extraction processing conditions.
