你可能喜欢从茶叶中提取咖啡因
从中提取因，对于茶叶相信大家都有非常熟悉，这是人们常备的饮品。并且，我国很多地方以中茶为生，并著有茶道。但是，对于茶叶我们真正的了解吗?茶叶中含有咖啡因，并且，咖啡因有提神的功效，利尿，增强脏的排泄功能等。所以，我们要正确的利用茶叶。很多专家学者想要提取茶叶中的咖啡因进行研究，那么如何提取呢?以下就为大家详细的介绍一下。
茶叶中含有很多物质，咖啡因就是其中的一种。我国一直在研究如何提取茶叶中的咖啡因，提取的方法也越来越多。从茶叶中提取咖啡因，但是，如何提取既简单又有效呢?相信很多朋友都不了解，具体的来介绍。
近年来中外学者对升华法制取天然咖啡因的方法做了大量研究和改进，并申请了专利〔1～7〕。叶春园等把茶叶末投入备有搅拌器的升华罐中，用U形加热管中的电热丝把机油加热到(130±10)℃，用油泵把热油打入升华罐的夹层中，搅拌，用真空泵抽气，保持升华罐内的真空度为50.66
h，挥发物经导管进入冷凝罐冷水冷却，保持30℃～60℃，从冷凝罐的底部取出固体冷凝物(粗咖啡因)，加少量水溶解，漂去焦油，经结晶纯化后可得纯咖啡碱，10
kg茶叶下脚料可制得180
g咖啡因，得率1.8%。陈友仁等设计了新的咖啡因提取装置，升华罐与冷凝罐直接连接，升华罐底部用远红外加热炉加热，冷却分离罐由分离罐体、收集网、环形集水槽、水冷却夹套进出水管、烟道和搅拌驱轴组成。
上述就是对如何提取茶叶中的咖啡因做了介绍，希望能给朋友们带来帮助。对于茶叶我们的需求量是比较大的，从茶叶中提取咖啡因，并且茶叶中的很多成分对人体也有很大的帮助。所以，我们要正确的认识茶叶，多了解茶叶的相关知识，科学养生。
