Abstract
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.

A demineralised whey powder, obtained 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 in this manner, to dialysis;
- and
- (e) dehydrating the diluate such obtained.
A process for the production of a demineralised whey powder, comprising the following steps:
- (a) separating raw milk into skimmed milk and cream;
- (b) microfiltrating or microdiafiltrating the skimmed milk, obtaining a whey protein-rich permeate P1 and a retentate R1 containing casein and GMP;
- (c) separating the lactoferrin from the permeate P1 by means of column chromatography;
- (d) dialysing the permeate P1 from which lactoferrin had been removed;
- (e) drying the diluate, obtaining a product in powder form.
