Abstract
The present invention relates to a method for treating raw human milk to produce treated human milk having undetectable levels of bacteria. The milk is skimmed to produce skim human milk then subjected to microfiltration to yield a filtrate which has undetectable levels of bacteria, including Bacillus cereus. The resultant human milk can be further processed, used and/or sold.
Claims17
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.

A method for making a human milk composition comprising the steps of:
- (a) pre-filtering human skim milk comprising about 0.1% to about 1.0% fat content 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 about 50 g/L, and wherein the filter aid has a permeability of about 0.300 D;
- (b) microfiltering the pre-filtered human skim milk through one or more microfilters to obtain a microfiltered human skim milk;
- (c) concentrating the microfiltered human skim milk to obtain concentrated human skim milk, wherein the concentrating comprises ultrafiltration with an ultra-filter between about 1 to about 40 kDa in size;
- (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.
