Abstract
The invention relates to a process for the preparation of milk and milk powders having a long storage life utilizing techniques which are known per se. To that end, a milk liquid is prepared, which is evaporated, and a fat fraction is added to the milk liquid in one or more effects of the evaporator. This process is particularly suitable for the preparation of a milk having a long storage life, in which unsaturated fatty acid chains are present.
