Abstract
Abstract Liquid coffee extract is brought up to the relatively high solid content of between about 35 and 50% solids by the addition of various nutritive ingredients and then slowly and continuously cooled from about 35* to 40*F to between -14*F and -20*F over a period of at least 40 minutes. The extract is then thoroughly frozen and freeze dried to a stable moisture content to yield a dry, soluble coffee product having an improved and acceptable rate of solubility.
