Claims
- 1. The method of preparing a textured, puffed, proteinaceous food product comprising subjecting water-moistened, hydrophilic proteinaceous material having a protein content of at least about 30% on a dry weight basis and an effective amount of water within the range of about 10 to 50% to working under effective mechanical pressure and sufficient temperature conditions of more than about 100.degree.C. to convert it to a hot, moist, plastic extrudable mass and extruding said hot plastic mass through and from a length of an elongated die under non-puffing conditions to provide a moisture-containing, unpuffed, substantially homogeneous, translucent to glassy, extruded product, recovering said extruded product, and, as a separate and distinct operation, thereafter puffing said recovered product in a moist state by subjecting it to water-boiling puffing conditions.
- 2. The method of claim 1 wherein said proteinaceous material comprises defatted soy protein.
- 3. The method of preparing a textured, puffed, proteinaceous food product comprising subjecting water-moistened, hydrophilic proteinaceous material having a protein content of at least about 30% on a dry weight basis and an effective amount of water within the range of about 10 to 50% to working under effective mechanical pressure and sufficient temperature conditions of more than about 100.degree.C. to convert it to a hot, moist, plastic extrudable mass and extruding said hot plastic mass through and from a length of an elongated die under non-puffing conditions to provide a moisture-containing, unpuffed, substantially homogeneous, translucent to glassy, extruded product, recovering said extruded product, and, as a separate and distinct operation, drying said recovered product under non-puffing conditions to reduce its moisture content but leave residual moisture, and, as a separate and distinct operation, thereafter puffing said dried product having residual moisture by subjecting it to water-boiling puffing conditions.
- 4. The method of claim 3 wherein said proteinaceous material comprises defatted soy protein.
