Is CO2 method of decaffeination safe?

The CO2 process is a natural, safe process that preserves the beans’ innate chemical makeup. The result is wonderfully, rich, flavorful coffee. We at QueenBean Coffee Company ran a few taste tests with our regular French Roast and French Roast decaf (CO2 processed) coffees.

How does CO2 decaffeination work?

In the carbon dioxide decaffeination process, green coffee beans are soaked in highly compressed CO2, which extracts the caffeine. The caffeine is then removed from the CO2 using activated carbon filters, which are then reused to extract caffeine from the coffee again.

How is decaf supercritical CO2?

Supercritical CO2 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.

What process is used to make decaf?

The most-common methods of decaffeination involve chemical solvents, usually ethyl acetate or methylene chloride. In the direct method, the coffee beans are steamed and then rinsed repeatedly with the chemical solvent to flush away the caffeine.

2 The beans are then placed in contact with liquid CO2 under subcritical conditions. During extraction the liquid CO2 continuously draws caffeine out of the coffee beans. The caffeine is dissolved in the liquid CO2.

What is supercritical CO2 used for?

Supercritical carbon dioxide is used to remove organochloride pesticides and metals from agricultural crops without adulterating the desired constituents from the plant matter in the herbal supplement industry.

What is supercritical fluid used for?

The use of supercritical fluids as extraction solvents for organic food products has been long established. Applications in the food and drink industry include coffee decaffeination, production of natural colourants, milk sterilisation and deodorising fish oils.
