ABSTRACT:
A process for removal of caffeine from green coffee beans is disclosed by extraction with an aqueous liquid and preferential adsorption of caffein from the extract by means of a synthetic polymer resin of the type that is obtainable by polymerization or copolymerization of monomers containing aromatic ring systems and acid groups, and whereby the ratio of the total adsorption capacity for caffein to the total ion exchange capacity is larger than about 1 and smaller than about 25.
