Abstract: Problem to be Solved An object of the present invention is to provide a method for producing a textured protein material having a meat-like fibrous texture. Solution The textured protein material having a meat-like fibrous texture can be produced by feeding a flat-sheet-like textured protein material prepared via pressurization and heating, and then extrusion by an extruder through cutting blade rolls composed of a pair of rolls facing each other and having a plurality of square-blade-like annular blades arranged in parallel, thereby making slits sheared on the topside and the underside of the textured protein material in the same direction as the extruded direction.
