<p>COFFEE EXTRACT DECAFFEINATION METHOD A method of decaffeinating caffeine-containing liquids and particularly aqueous coffee extracts is disclosed. Caffeic acid is added to a caffeinecontaining aqueous coffee extract so as to form an insoluble, colloidal caffeic acid/caffeine complex. Crystals of the insoluble caffeic acid/caffeine complex are then grown and subsequently separated from the aqueous decaffeinated coffee extract. The coffee extracts intended for use herein include both roasted and green coffee extracts. 30005-B</p> |
