Abstract
The present invention provides methods for treating milk products to reduce the bacteria and fat therein and/or to recover proteins therefrom. In particular, the present invention provides a method of treating a milk product comprising dynamically filtering the milk product (particularly skim milk or whey) through a filtration medium having a pore rating of about 0.1-1 .mu.m to produce a fat-depleted milk product permeate. The present invention also provides a method of concentrating a protein in a milk product comprising dynamically filtering the milk product through a filtration medium to form a protein-enriched retentate or a protein-enriched permeate. This method can be repeated with the protein-enriched fraction using filtration media of increasingly smaller pore ratings in order to recover particular proteins or combinations of proteins (from among many proteins in the milk product).
