  • Patent number: 5026572
    Abstract: A method of making a jerky-type product is provided which uses multiple extrusion steps. First, a blend of a wet beef product and a high protein flour are mixed and then cooked by extruding the first blend at a temperature sufficient to at least partially cook the beef in the first blend. Next, a second blend is formed which includes the extruded product of the first extrusion step and additional wet beef. The second blend is then cooked by extruding the second blend at a temperature sufficient to cook the wet beef in the second blend. Finally, the material from the second blend is processed into jerky form.
