PURPOSE:To obtain a laminated food showing a dried bean curd-like taste, by extruding a protein raw material comprising oil stuff seed protein and gluten as main components and water from a slit die under pressure and under heating by the use of a twin screw extruder. CONSTITUTION:1pt.wt. oil stuff seed protein (e.g., soybean protein), 0.1-2pts.wt. gluten and water in an amount to give 25-40wt% water content of raw material are blended. Then, the blend is extruded from a slit die under pressure and under heating by the use of a twin screw extruder, to give the aimed laminated food. Properly the front part of barrel of the twin screw extruder is heated at 70-100 deg.C, the heating part at 100-180 deg.C and the tip melting part at 160-190 deg.C. The narrower width of opening of the slit die is properly <=6mm. Consequently, a food having a liminated texture and a densely aggregated fibrous texture of each single layer can be produced. |
