safety - Can caffeine be separated from coffee?


Is there a way to extract caffeine from coffee completely?



Answer




Regarding "completely":


The short answer is no.


But for all intents and purposes, yes.


By submitting coffee to several small volume extractions, one can drastically reduce the concentration of caffeine present in the grains. This method of extraction (multiple small volume aliquots) is more effective than a single large volume extraction. The link I shared provides a good discussion.
