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.
Claims2
A method for producing a textured protein material, comprising:
- forming by an extruder, a sheet-shaped protein material having a porous structure prepared via pressurization and heating;
- and
- then treating the sheet-shaped protein material by an apparatus comprising cutting blade rolls, wherein the apparatus comprises a pair of the cutting blade rolls facing each other,
- thereby
- making slits sheared on a top surface and an under surface of the sheet-shaped protein material in the same direction as an extruded direction thereof, so that the textured protein material in a sheet shape is formed,
- wherein each of the pair of the cutting blade rolls comprises a plurality of annular blades arranged in parallel to each other,
- a pitch width between adjacent annular blades of the cutting blade rolls ranges from 0.8 to 1.5 mm,
- a clearance width between ends of the annular blades of the pair of rolls is in a range from 10 to 30% relative to a thickness of the sheet-shaped protein material formed by the extruder, the thickness of the sheet-shaped protein material formed by the extruder being in a range from 2 to 5 mm,
- each of the plurality of annular blades comprises a square blade that has a flat surface with opposing sides, a pointed corner at each of the opposing sides of the flat surface, and each pointed corner has an angle of 90° between the flat surface and the annular blade,
- the slits are pits and projections formed on the top surface and the under surface of the sheet-shaped protein material by press-cutting the top surface and the under surface thereof with the plurality of annular blades, and
- protein in the textured protein material consists of plant protein.
