DECAFFEINATION PROCESS

摘要

A process is disclosed wherein the decaffeination of aqueous extracts of vegetable material with non-ionic, hydrophobic resin may be performed in a continuous manner. In accordance therewith, extract is contacted with resin to effect decaffeination, exhausted resin containing adherent caffeine and non-caffeine water solubles is leached with water to remove the caffeine, the caffeine-free resin is then washed with a solution comprising water and an organic solvent to elute noncaffeine water solubles and then the resin is ?osed with water to permit its reuse in the further decaffeination of vegetable material extracts.
