Abstract

Procedure to produce a decaffeinated vegetable material, where vegetable material containing caffeine is extracted with a volume of liquid fatty material immiscible in water and recirculating in a decaffeination zone, characterized in that in said extraction it is verified for a sufficient period of time for transferring caffeine from said plant material to said fatty material, and wherein the caffeine-laden fatty material resulting from the extraction is separated from said plant material and is led to a regeneration zone for the separation of caffeine before recirculation to said decaffeination zone, the separation of said caffeine in said regeneration zone by vaporization is understood.
