AdministratorIs 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.
What is CO2 decaffeination?
In the Carbon Dioxide Process of decaffeinating coffee, green coffee beans (milled but not yet roasted) are soaked in supercritical carbon dioxide (highly compressed carbon dioxide) at 73 to 300 atmospheres of pressure for about ten hours, which extracts the caffeine from the coffee beans.
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.
How much caffeine is in decaf CO2?
Decaf coffee is not caffeine free, as each cup contains about 0–7 mg. However, this is much less than the amount found in regular coffee.
What decaf coffee is Swiss water processed?
The Swiss Water Company headquartered in Burnaby, BC, Canada is the only decaffeination facility that is certified organic and Kosher. All decaf Kauai Coffee is grown and harvested on Kauai and sent to the Swiss Water® Company facility for chemical-free decaffeination.
What is the decaffeination process?
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.
The CO2 decaffeination process is one of just two that removes caffeine from coffee without using chemicals. Learn all about the process here. Decaf coffee sits on all grocery store shelves and a bag or two may be sitting in your kitchen right now.
Why is supercritical carbon dioxide used for decaffeination?
Supercritical Carbon Dioxide. The supercritical state of carbon dioxide is superior to water in this process because it has the desirable diffusive properties of a gas yet an increased density like a liquid. An advantage of this decaffeination method is the avoidance of the use of potentially harmful chemical solvents.
How is decaffeinated coffee made?
Decaffeinated Coffee : Carbon Dioxide Methods. In the most widely used CO2 process the steamed beans are bathed in the compressed carbon dioxide and the caffeine is removed from the carbon dioxide through charcoal filtering, just as it is in the water-only process. However, the flavor components remain in the bean throughout the process,…
What are the health benefits of decaffeinated coffee?
This results in a coffee that’s slightly less healthy than the origin, unaltered coffee, but is suitable for those with caffeine sensitivity or want to reduce their caffeine intake and help deal with withdrawal side effects. It also reduces the acidity of the coffee, resulting in a smoother tasting coffee.
