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.
