摘要
A method of extracting caffeine from green coffee beans whereby an essentially caffeine-free supercritical fluid is continuously fed to one end of an extraction vessel containing green coffee beans and caffeine-laden supercritical fluid is continuously withdrawn from the opposite end. A portion of decaffeinated beans is periodically discharged while a fresh portion of undecaffeinated beans is essentially simultaneously charged to the extraction vessel. The caffeine-laden supercritical fluid is fed to a countercurrent water absorber. Supercritical carbon dioxide is the preferred supercritical fluid. The method of the present invention is more efficient than batch processes and produces an improved decaffeinated coffee.
