Abstract:
The present invention concerns a method for concentrating dairy proteins. The method includes producting and using negatively-charged ultrafiltration membranes to achieve high hydraulic permeability with low sieving coefficients. The method thus yields good protein concentration at a fast rate.

Claim (Index 1):
A method of concentrating dairy proteins, the method comprising:\n (a) providing a protein mixture containing dairy proteins; (b) ultrafiltering the mixture of step (a) using a negatively charged ultrafiltration membrane wherein the ultrafiltration membrane has a molecular weight cutoff of 100 kDa or greater and a negative charge of more than 3 milliequivalents per square meter; and (c) conducting the ultrafiltering of step (b) under conditions that yield a hydraulic permeability of more than 120 Liters per hour per square meter per bar, a protein sieving coefficient of no more than about 0.05 of the dairy proteins, and a permeate flux (J v ) at least 6-fold higher than when conducting ultrafiltration of milk serum using a neutral 10 kDa membrane, thereby producing concentrated dairy proteins.
