ABSTRACT A process of producing soluble coffee is described involving the steps of air cooling freshly roasted coffee beans followed by quenching the beans with liquid nitrogen and freez- ing the beans. The frozen beans are then subjected to a grind- ing operation to produce a colloidal coffee product having a particle size less than 45 µ. The frozen colloidal product is then added to a chilled coffee extract prepared by conventional methods and is blended with the extract using a homogenizer. The coffee extract containing the colloidal coffee product is then spray-dried or freeze-dried to produce a soluble coffee powder. The soluble coffee powder is found to contain regular coffee aromatic notes and possesses a regular coffee flavor. -2-
