摘要
采用索氏提取器从茶叶中提取咖啡因的方法具有提取率低、操作繁琐、耗时长的缺点,为了克服这些缺点,实验采取多种途径改进了实验方法,对比实验结果表明,各改进后的实验方法均提高了咖啡因的提取率,综合改进方法使提取率提高了1倍,大大缩短了提取时间。
Using soxhelt extraction apparatus, the method of extracting caffeine from tea has low extraction rate, the tedious, time-consuming operation long weakness, in order to overcome those shortcomings, many kinds of ways to improve the experiment method were adopted. The contrast experiment showed that the im- proved methods an could improve extraction caffeine,the comprehensive improvement method could double the extraition rate of caffeine and shorten extraction time significantly.
