Continuous method for dissolving milk proteins containing water insoluble casein by passing said milk proteins together with one or more solubilizers and with water in a continuous stream through a closed reaction chamber by means of a positive displacement pump and converting the mixture within said reaction chamber under the influence of shearing forces into a solution having a dry solids content within the range of from 20 to 70% by weight. The solution can be removed from the reaction chamber as liquid jets which are dried while forming endless threads or films which can be cut or milled. Water soluble milk protein product having a particle density amounting to at least 90% of the specific density. Apparatus for performing said method containing a positive displacement pump and a closed reaction chamber connected to said pump by way of the discharge conduit of said pump, in which reaction chamber preferably a rotary means, such as a colloid mill or a serrated impeller, is provided.
