摘要
用萃取法从茶叶中提取咖啡因,探讨氧化钙量、焙烧温度及升华温度对咖啡因产率的影响,通过正交实验法得到的最佳提取条件为:氧化钙量4 g,焙炒电压100 V,升华电压为150 V,最佳条件下,咖啡因产率可达1.83%.该方法具有操作简便、时间短、产率高的特点.
A improvement method is described for the extraction of caffeine from tea. The influence of quantity of Calcium Oxide, roasting voltage and sublimation of caffeine voltage is discussed. The technological parameters optimized by orthogo- nal test are as follows： the quantity of Calcium Oxide is 4g, roasting voltage is 100 V and sublimation voltage is 150 V, the highest yield of caffeine is highest 1.83%. This method is convenient, short time and high yield.
