Abstract

A method for producing milk with a lowered bacterial content is provided. Raw milk is divided by centrifugal separation into one fraction consisting of cream and another fraction consisting of skim milk. The skim milk fraction is directed into a microfilter in which part of the fat globules, protein, and bacteria are separated off. From the microfilter there is obtained a permeate which consists of skim milk having a lowered fat, protein and bacterial content, and a retentate having an increased fat, protein and bacterial content. The retentate is subsequently sterilized.
