ABSTRACT:
In a method for preparing caseinates, including the introduction of casein, alkaline solutions or basic salts and water into an extruder, the constituents being thoroughly mixed together and then subjected to an increase in pressure and temperature under the influence of return elements, it is provided, to achieve a finished basic product while avoiding a separate comminuting stage following the extrusion process, that the pressure built-up under the influence of return elements or kneading units takes place directly in front of the discharge end of the extruder and the product be discharged freely through this end of the extruder. An apparatus is used to carry out the method, this apparatus being characterised in that the return elemnts or return kneading units are arranged directly in front of the discharge end of the extruder and the discharge end of the extruder is open essentially without any reduction in cross-section relative to the free cross-section of the extruder.
