The present invention relates to a method for the production of commercially sterile skimmed milk. After separation, the skimmed milk fraction is treated by microfiltration in one or more steps. The microfiltration gives a permeate flow and a retentate flow, in which all microorganisms of a given size have effectively been separated from the permeate flow. After the microfiltration, the permeate flow is heat treated at a temperature of 72-134 DEG C during a requisite period of time. In order to obtain a sterile skimmed milk which is as good as free of destroyed microorganisms, the retentate flow is not employed. |
