摘要

Producing long-life milk, comprises: a separation step, including centrifugation through which the raw milk is separated into a cream part with high fat content, and a skimmed milk part with preserved low fat skim milk content; subjecting to a mechanical treatment for the separation of microorganisms and/or their spores; and heating to obtain an intermediate product, optionally after pasteurization and/or cooling in a heat treatment process at a temperature of more than 135[deg] C, preferably >= 140[deg] C. An independent claim is also included for a device for carrying out the above mentioned method, comprising a separator to separate the raw milk into skimmed milk part and cream part, a mechanical device including a Bactofuge(RTM: Centrifuge to decrease the bacteria and spore content of milk) for the separation of microorganisms and/or their spores from the skimmed milk part and a heat treatment device for heating obtained intermediate product by the mechanical treatment of the skimmed milk part at a temperature of >= 135[deg] C, preferably >= 140[deg] C.
