초록

Primary extraction of ground roasted coffee. The coffee is first extracted with an amount of aqueous extraction liquid sufficient to extract substantially all of the dry soluble solids from the coffee, but preferably not so large that the extract must be concentrated for further processing. The coffee is next extracted with an aqueous extraction liquid to extract hydrophobic flavor components. The hydrophobic flavor components are removed from the resulting extract by stripping and recovered as a concentrated aqueous solution.

A multi-stage method for the primary extraction of ground roasted coffee, comprising the following two integrated steps: (a) passing a stream of ground roasted coffee through a number of stages, at elevated temperatures between 60°and 120°at which substantially no hydrolysis of coffee solids occurs, countercurrently to a stream of aqueous extraction liquid to produce an extract of predetermined concentration, the ratio of liquid to coffee being in the range of 1.5:1 to 3:1, said aqueous extraction liquid extracting substantially all the soluble solids fr...
