簡單食品知識 深焙咖啡和淺焙咖啡哪一個咖啡因的含量比較高?
4 years ago

咖啡已经是现代人不可或缺的伴侣,
没了咖啡因,身体仿佛就进入不了清醒模式。
今天我们不谈咖啡因和人体健康的关系,
我们来探讨一下深焙咖啡和浅焙咖啡,
究竟哪一种咖啡因含量比较多。
这是个在咖啡界争辩已久的话题。
许多人认为,深焙咖啡味道浓郁,
所以其中含有的咖啡因会更多。
但也有人认为,烘焙的时间越久,
咖啡豆里的咖啡因就挥发得越多,
因此深焙咖啡的咖啡因含量会少一些。
但事实上这两种说法都是错的。
据专业人士称,咖啡豆里的咖啡因,
要达到600℃以上才会开始挥发,
不管是深焙还是浅焙,烘焙过程中的温度,
最高也不超过220℃,挥发的都是水分和其他物质,
因此,两种咖啡豆的咖啡因含量是相同的。
而在制作咖啡的过程中,
浅焙咖啡豆含水量较多,深焙咖啡豆含水量少,
因此制作同样重量的咖啡,
需要的浅焙咖啡豆的量就比较少,
因而会让人产生一种错觉,
感觉浅焙咖啡的咖啡因含量会比较低。
