A demineralised whey powder is suggested which is obtainable by: (a) Separating raw milk, removing the cream; (b) Subjecting the skimmed milk such obtained to microfiltration or microdiafiltration, obtaining a whey protein-rich permeate P1 and a retentate R1 containing casein and GMP in the process; (c) Subjecting the permeate P1 to column chromatography separation, in which the lactoferrin contained therein remains on the column; (d) Subjecting the permeate, from which lactoferrin had been removed, to dialysis; and (e) Dehydrating the diluate such obtained.
