Supercritical Carbon Dioxide Decaffeination of Coffee ...

Supercritical, carbon dioxide, (sCO 2) has decaffeinated coffee since the 1970s. The process employs ethanol or water as a co-solvent to contradict the low solubility of caffeine in sCO 2. Green coffee beans are soaked in hot water inside a sealed extraction container till they are 50% saturated with water to bring out the caffeine [3].

How Is Decaf Coffee Made? - How To Decaffeinate Coffee Guide
How Is Decaf Coffee Made? - How To Decaffeinate Coffee Guide

The carbon dioxide which exits the vessel used for extraction is caffeine-rich and handled in one of two ways. It’s either passed through a bed of activated charcoal or through a water ‘bath’ tower to rid it of the caffeine. Then it’s sent back to the vessel used for extraction. Supercritical carbon dioxide decaffeination is …
