1. A method for making a human milk composition comprising the steps of:
(a) pre-filtering human skim milk using a filter aid through one or more pre-filters to obtain pre-filtered human skim milk, wherein the filter aid is added to the human skim milk in a concentration of from about 20 g/L to about 50 g/L, and wherein the filter aid has a permeability of from about 0.100 D to 0.300 D;
(b) microfiltering the pre-filtered human skim milk through one or more microfilters to obtain microfiltered human skim milk;
(c) concentrating the microfiltered human skim milk to obtain concentrated human skim milk, wherein the concentrating comprises ultrafiltration;
(d) formulating the concentrated human skim milk to obtain the human milk composition, wherein the formulating comprises adding cream to the concentrated human skim milk.
