1. Organic Solvent Processes – Direct Method. The oldest decaffeination method and also the most common is the direct solvent method.. In this method, the ,coffee, beans are steamed to open their pores and rinsed with a solvent like methylene or ethyl acetate.. The caffeine’s ,extraction, occurs during the rinsing step as the caffeine selectively unites with the solvent molecules.

In this case, however, the CO 2 has a very special characteristic: it’s supercritical. And thus, an ideal partner for the decaffeination process in our experts’ laboratories. In highly complex plants like these, thyssenkrupp experts extract the caffeine from the coffee beans with the help of supercritical carbon dioxide and a lot of pressure.

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 …

1/2/2014, · Coffee was one the first raw materials to be processed by supercritical fluid extraction, mainly for decaffeination purposes. It is thus likely that also SCG become matter of this technology, particularly if one takes into account that SFE is already applied to produce decaffeinated coffee.
