The Supercritical Carbon-Dioxide Extraction Process is the most recent development for decaffeinating coffee beans. When carbon dioxide (CO2) is under 100 times the amount of pressure than it is at sea level, it begins to behave like a liquid. This state is called ‘ supercritical ’.

This process is identical to one of the techniques for making ,decaffeinated coffee,. In ,supercritical, fluid ,extraction,, high pressure carbon dioxide gas (up to 100 atm.) is used as a solvent. Due to the low heat of process and the relatively unreactive solvent used in the ,extraction,, the fragrant compounds derived often closely resemble the original odour of the raw material.

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.

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.
