  • Method of deflavoring whey protein using membrane electrodialysis
    Patent number: 7582326
    Abstract: Whey protein materials such as whey from cheese making processes, whey protein concentrates, and whey protein isolates, are deflavored by adjusting the pH of an aqueous composition of such whey protein materials to about 8.0 to about 12 using membrane electrodialysis to solubilize the whey proteins and to release the flavoring compounds and thereafter passing the pH-adjusted composition to an ultrafiltration membrane having a molecular weight cutoff up to about 50,000 Daltons under conditions at which the flavoring compounds pass through the membrane, leaving the retained whey protein material with improved flavor.
    Type: Grant
    Filed: August 22, 2005
    Date of Patent: September 1, 2009
    Assignee: Kraft Foods Global Brands LLC
    Inventors: Peter H. Brown, Colin P. Crowley
  • Method of deflavoring soy-derived materials using electrodialysis
    Patent number: 7175869
    Abstract: Soy derived materials such as soy milk, soy flour, soy concentrates, and soy protein isolates, are deflavored by adjusting the pH of an aqueous composition of such soy derived materials using membrane electrodialysis to a pH of about 9 to about 12 to solubilize the soy proteins and to release the flavoring compounds and thereafter passing the pH-adjusted composition to an ultrafiltration membrane having a molecular weight cutoff up to about 50,000 Daltons under conditions at which the flavoring compounds pass through the membrane, leaving the retained soy material with improved flavor.
