响应面法优化黄花菜挥发油同时蒸馏萃取条件

Optimization ptimization of simultaneous distillation extraction conditions of daylily volatile oil by response surface method

为了充分提取黄花菜中的挥发性香味成分,利用响应面分析法优化黄花菜挥发性香味成分的同时蒸馏萃取条件。结果表明:同时蒸馏萃取黄花菜香味物质的适宜条件为:温度60.87℃,时间3.05h,液料比10.47,优化后黄花菜挥发性香味成分的总量为1.711mg/g。

In order to fully extract volatile flavor components of daylily,simultaneous distillation extraction（SDE）conditions of volatile flavor components were optimized by response surface analysis.The results showed that the suitable SDE condition for flavoring substances was that the temperature was 60.87 ℃,time was 3.05 h,ratio of liquid and crude material was 10.47.Under the optimized condition,the total volatile flavor component of daylily was 1.711mg/g.
