- 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。
- Abstract:
- 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 improved methods an could improve extraction caffeine,the comprehensive improvement method could double the extraition rate of caffeine and shorten extraction time significantly.
