  • Fractionation of whey proteins by complex formation
    Patent number: 6900290
    Abstract: Disclosed is a method of fractionating ?-lactalbumin from ?-lactoglobulin in whey or whey protein concentrate. The method includes the steps of contacting whey or whey protein concentrate with a complexing agent so that the complexing agent forms insoluble complexes with ?-lactoglobulin present in the whey or whey protein concentrate. The insoluble complexes are then separated from the whey or whey protein concentrate, thus yielding a precipitate that is predominately ?-lactoglobulin and is substantially devoid of ?-lactalbumin, and a supernatant that predominately ?-lactalbumin and is substantially devoid of ?-lactoglobulin.

  • Fractionation of whey proteins by complex formation
    Publication number: 20030004316
    Abstract: Disclosed is a method of fractionating &agr;-lactalbumin from &bgr;-lactoglobulin in whey or whey protein concentrate. The method includes the steps of contacting whey or whey protein concentrate with a complexing agent so that the complexing agent forms insoluble complexes with &bgr;-lactoglobulin present in the whey or whey protein concentrate. The insoluble complexes are then separated from the whey or whey protein concentrate, thus yielding a precipitate that is predominately &bgr;-lactoglobulin and is substantially devoid of &agr;-lactalbumin, and a supernatant that predominately &agr;-lactalbumin and is substantially devoid of &bgr;-lactoglobulin.
