PURPOSE:To economically produce a grain-gluten bread, having improved secondary processability, flavor and taste and capable of embrittling and readily pulverizable in a short time, by heat-treating the grain-gluten bread in a twin- screw extruder under pressure. CONSTITUTION:Grain-gluten bread, e.g. wheat-gluten bread, is heat-treated in a twin-screw extruder under pressure. The twin-screw extruder may be extruder, having improved extrusion driving force and moderate shearing force and capable of giving sufficient energy from the outer cylinder barrel and a twin-screw type completely meshing corotating extruder having improved mixing and kneading property is particularly preferred. The barrel temperature is preferably 120-150 deg.C and the amount of dehydration is preferably 30-50pts.wt. based on 100pts.wt. grain-gluten bread. Thereby, the aimed grain-gluten bread having improved secondary processability and flavor and taste and capable of embrittling and readily pulverizable with little smell of grain-gluten bread can be economically produced in a short time. The grain-gluten bread suitable for secondary processing use, e.g. confectionary and bakery, etc., is obtained. |
