ABSTRACT:
Disclosed is a method of fractionating α-lactalbumin from β-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 β-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 β-lactoglobulin and is substantially devoid of α-lactalbumin, and a supernatant that predominately α-lactalbumin and is substantially devoid of β-lactoglobulin.
