FRACTIONATION METHOD FOR WHEY PROTEIN, PRODUCTION METHOD FOR COMPOSITION INCLUDING -LACTALBUMIN, AND PRODUCTION METHOD FOR COMPOSITION INCLUDING -LACTOGLOBULIN

摘要

A method for fractionating whey proteins, including: preparing a solution including a first whey protein and a second whey protein and separating the first whey protein and the second whey protein with a membrane; wherein the first whey protein forms a complex with at least one of carbonate ion, hydrogen carbonate ion, a light metal ion, and a transition metal ion; and the second whey protein satisfies at least one of the following (1) and (2): (1) the second whey protein forms no complex with any of the carbonate ion and the hydrogen carbonate ion; (2) the second whey protein forms no complex with any of the light metal ions and the transition metal ions.
