    • 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 a bacteria and fat-depleted 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).
    • 本发明提供了用于处理乳制品以减少其中的细菌和脂肪和/或从其中回收蛋白质的方法。 特别地,本发明提供了一种处理乳制品的方法,其包括通过具有约0.1-1μm孔径的过滤介质动态过滤乳制品(特别是脱脂乳或乳清)以产生脂肪贫乏的乳制品 渗透。 本发明还提供将蛋白质浓缩在乳制品中的方法,其包括通过过滤介质动态过滤细菌和脂肪贫乏的乳制品以形成富含蛋白质的滞留物或富含蛋白质的渗透物。 使用越来越小的孔隙等级的过滤介质,可以用富含蛋白质的级分重复该方法,以便回收特定蛋白质或蛋白质组合(从乳制品中的许多蛋白质中)。
