<p>DECAFFEINATION WITH TREATED ACTIVATED CARBON An aqueous coffee extract is decaffeinated with a treated activated carbon. The activated carbon is first contacted with an ethyl cellulose solution in order to adsorb the ethyl cellulose on the carbon. The ethyl cellulose-containing activated carbon is then dried and contacted with an aqueous coffee extract. The substantially decaffeinated extract is subsequently separated from the carbon. 30006-E</p> |
