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 bleached with water to remove the caffeine, the caffeine-free resin is then washed with a solution comprising water and an organic solvent to elute non-caffeine water solubles and then the resin is rinsed with water to permit its reuse in the further decaffeination of vegetable material extracts.
