摘要：
A process is disclosed wherein the decaffeination of solutions of caffeine in fatty media is effected with hydrophilic, phenol/formaldehyde polymeric resins having phenolic functional groups. In particular, the solutions are contacted with resin to effect decaffeination and the solvent medium is recovered, whereas the exhausted resin containing adherent caffeine and any non-caffeine solids may be regenerated for re-use. Other features of the invention are described in the specification.
