När upptäcktes koffein?

Koffein upptäcktes av den tyske kemisten Friedrich Ferdinand Runge 1819 och isolerades första gången av honom året efter. Han myntade begreppet ”kaffein”, en kemisk förening i kaffe som i Sverige fick namnet koffein. Koffein återfinns i olika mängder i bönor, blad och frukter hos över 60 olika växter.

Hur tillsätts koffein?

Koffein finns naturligt i alla sorters kaffebönor och är därför en naturlig del av kaffet. I andra drycker, såsom coca-cola och energidryck, tillsätts det dock för att ge den uppiggande effekten. Det tillsätts då i sin renaste form och är ett vitt pulver utan någon speciell smak.
