Abstract
An improved roast and ground coffee extract decaffeination method which involves partitioning non-caffeine solids from caffeine and returning the non-caffeine solids to a decaffeinated coffee product for improved flavor and economics. Liquid-liquid extraction is used to partition the non-caffeine solids into an aqueous phase from a caffeine-solvent phase. Caffeine is recovered from the caffeine-solvent phase as a valuable byproduct.
