## Abstract

The invention relates to a method for producing a milk-based product, comprising the steps of: providing a milk raw material; altering a ratio of casein to total protein of the milk raw material to less than about 0.80; subjecting the milk raw material with the altered ratio of casein to total protein from step b) to a heat treatment at the temperature of at least about 150° C. for a period of at most about 0.3 sec; cooling the heat-treated milk raw material from step c) to provide the milk-based product. The method provides milk-based products with long shelf life and good organoleptic properties.
