A method of manufacturing a food product that includes the steps of: delivering a protein and water-containing carrier material to a turboreactor which has a cylindrical reaction chamber with a substantially horizontal longitudinal axis and with a rotor equipped with blades and rotatable about its longitudinal axis provided in the reaction chamber. The rotor is rotated at a speed sufficient to centrifuge the carrier material against an inner wall of the reaction chamber and to form a dynamic, turbulent layer at the inner wall. The carrier material is heat treated and dried in the reaction chamber and is then advanced in the direction of an outlet from the turboreactor. The heat-treated and dried carrier material as a food product is withdrawn from the outlet, wherein an atmosphere of superheated steam is generated in the reaction chamber.
