Abstract
A method for solubilizing partially extracted roasted and ground coffee in a fixed bed reactor in the absence of any added acid catalyst is disclosed. The hydrolysis is effective to achieve a soluble solids yield of about 55% to about 68% based on the original roasted and ground coffee and it effects minimal degradation of the soluble solids generated.
