Optimization of microwave-assisted hydro distillation extraction process of essential oil from Chestnut flower by response surface methodology

摘要: 利用响应面优化设计和SAS软件数据分析相结合的方法,以料液比、微波功率和提取时间为自变量,精油提取率为响应值,研究各个自变量以及其交互作用对微波辅助水蒸气蒸馏法(MAHD)提取板栗花精油得率的影响。根据二次回归模型和实际操作的可行性,得到修正后最佳提取工艺参数为:料液比1∶24(g/m L),微波功率300W,提取时间17min,在上述优化条件下,精油提取率为0.647%±0.030%。

Abstract: Effects of the solid-solvent ratio, microwave power and extraction time and their interaction on extraction rate of the essential oil from the Chestnut flower, extracted by the microwave-assisted hydro distillation, were researched and preparing technology was optimized using response surface design and data analyzed by SAS software. According to quadratic regression model and the feasibility of actual operation, the optimum extraction parameters were as follows:the solid-solvent ratio 1∶24 (g/m L) , microwave power 300 W and extraction time 17 min. Under the optimized conditions, the actual oil yield was 0.647%±0.030%.
