ABSTRACT The effects of material temperatures at the die, screw speed, and screw configurations on inactivation of protease in Arrowtooth flounder ( Atheresthes stomias )muscle were studied. No inactivation occurred below a material temperature of 40°C in the extruder die. Rapid destruction of protease in Arrowtooth flounder muscle occurred in the range 50–80°C. Complete inactivation of protease occurred at 100°C irrespective of screw speed and configuration. Protease inactivation was higher at low screw speed.
