PROCESS FOR PREPARING DECAFFEINATED COFFEE Gregory L. Bolt and Dennis R. Grubbs ABSTRACT A process for preparing a soluble decaffeinated coffee of improved flavor and aroma is described. The process comprises the steps of forming an aqueous extract of roast and ground coffee, decaffeinating the extract by contact with a water-immiscible organic solvent for caffeine, and separating the decaffeinated aqueous coffee extract from the caffeine- laden water-immiscible organic solvent. The coffee extract is improved in its flavor and aroma by incorporation of certain flavorful compounds separated from the caffeine-laden organic solvent. Caffeine is partitioned from the organic solvent by contact with water and the resulting organic solvent and its content of flavorful compounds is incorporated into the coffee extract.
