Abstract
The invention involves a process for the decaffeination of coffee, wherein--usually moistened--coffee is exposed to a circulating medium essentially composed of a compressed gas and an entrainer; this medium is subjected to partial condensation of the caffeine containing entrainer, in the absence of decompression; the caffeine is recovered from the condensate by evaporation of the entrainer portion thereof, and the medium is recycled to the coffee for continued extraction of caffeine therefrom.
