Chemistry of Coffee: Understanding Decaffeination Processes
Chemistry of Coffee: Understanding Decaffeination Processes

Supercritical, CO 2 has been used in industry to, extract caffeine, from coffee beans since the 1970s., Caffeine, has a low solubility in, supercritical, carbon dioxide and, for this reason, a co-solvent (either water or ethanol) is used which triples the, caffeine, solubility, hence accelerating the extraction.

Developing high-efficiency, low-cost power generation based on ,supercritical, carbon dioxide-based power cycles. The ,supercritical, carbon dioxide (,sCO 2,) power cycle operates in a manner similar to other turbine cycles, but it uses CO 2 as the working ,fluid, in the turbomachinery. The cycle is operated above the critical point of CO 2 so that it does not change phases, but rather undergoes ...

29/1/2020, · 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

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 …
