  • Iron-fortified soluble coffee and method for preparing same
    Patent number: 4006263
    Abstract: Liquid coffee extract having a solids concentration of from about 10 to 30% by weight is maintained at a temperature below about 70.degree.

  • Decaffeination process
    Patent number: 3989850
    Abstract: Decaffeinated coffee of improved quality is achieved using a process wherein caffeine-containing green coffee is countercurrently extracted with a water solution of coffee solubles. The decaffeinated coffee removed from the extraction zone is treated to remove surface solids contained thereon and is then dried at temperatures not in excess of 200.degree. F. The critical combination of a specified lower limit of surface solids on the coffee prior to drying and the drying temperature has been found to result in a decaffeinated coffee product of improved flavor.
