A PROCESS OF PREPARING SHAPED OILSEED PROTEIN PRODUCTS COMPRISING PREPARING A SOLUTION OF OILSEED PROTEIN HAVING A PROTEIN CONCENTRATION OF FROM ABOUT 10% TO ABOUT 30% AND A SUBSTANTIALLY CONSTANT VISCOSITY ON STANDING, CONTINUOUSLY FEEDING SODIUM HYDROXIDE INTO A STREAM OF THE PROTEIN SOLUTION TO PRODUCE AN INITIAL PH THEREIN IN THE RANGE FROM ABOUT 11.5 TO ABOUT 13.5. ALLOWING THE STREAM OF PROTEIN TO AGE FOR A TIME LESS THAN ABOUT ONE HOUR WHEREBY THE VISCOSITY OF THE STREAM OF PROTEIN WILL INCREASE, AND IMMEDIATELY THEREAFTER EXTRUDING THE RESULTING STREAM OF PROTEIN SPINNING SOLUTION THROUGH AN EXTRUSION DEVICE IMMERSED IN AN ACID COAGULATION BATH WHILE THE INCREASED VISCOSITY OF THE STREAM OF PROTEIN SPINNING SOLUTION IS WITHIN THE RANGE FROM 1/3 OF ITS PEAK VISCOSITY TO ITS PEAK VISCOSITY.
