摘要：
The present invention concerns concentrating dairy proteins. Methods of the invention include the production and use of negatively-charged ultrafiltration membranes to achieve high hydraulic permeability with low sieving coefficients. Milk proteins are value-added ingredients m foods. Milk proteins must be concentrated to remove water prior to spray drying. Ultrafiltration membranes are used for this purpose because not only is water removed, but also minerals, lactose, and non-protein nitrogen. This results in a spray dried milk protein powder that is higher in protein and more valuable than it would be if just water was removed.
