【摘要】 为探讨微波法提取沙溪蜜柚废弃物中黄酮的提取工艺,以沙溪蜜柚柚皮为原料,考查了微波功率、提取时间、乙醇浓度、料液比对黄酮提取率的影响.通过L9(34)正交设计试验优化出最佳提取工艺条件为:微波辐射功率为250W,辐射时间2min,乙醇浓度70%,料液比1∶70.在最优条件下黄酮的提取率为0.272%.更多还原

【Abstract】 In order to extract flavonoids from Shaxi pomelo peel by the microwave method,Shaxi pomelo peel was taken as raw material,microwave power,the extraction time,ethanol concentration,ratio of material to liquid on the extraction rate of flavonoids were subjected to research.The optimal conditions for the extraction of flavonoids through L9(34)orthogonal experimental design are as follows:microwave power 250W,radiation time 2min,ethanol concentration 70%,ratio of solid to liquid 1:70.The extraction rate of flavonoids under the optimal conditions was 0.272%.更多还原
