  • Process for freezing coffee extract prior to lyophilization
    Patent number: 3961424
    Abstract: This invention involves dispersing coffee extract in relatively warm immiscible liquid refrigerant wherein the temperature of the extract/refrigerant mix is maintained at about 15.degree.F. to the ice point of the extract. This permits the formation of large ice crystals whereby the finished product is darker and more coffee-like in color. Next the temperature of the mix is reduced to below -20.degree.F. and the frozen extract is separated from the refrigerant and is then freeze-dried.
