A method of manufacturing a protein-containing food product by means of heat-treating a protein and water-containing carrier material suitable for pumping in a turboreactor which has a cylindrical reaction chamber with a rotor equipped with blades in order to centrifuge the carrier material in the form of a dynamic, turbulent layer against an inner wall of said reaction chamber, heat-treating, drying to AW less than 0.6 and granulating the carrier material, advancing the carrier material in the direction of an outlet from the turboreactor, and forming individual food products from the carrier material; a protein-containing food product made by press molding of a carrier material that has been granulated and dried to an AW value of less than 0.6 and that is microbiologically stable, the carrier material being free of gelantized starch.
