Protease Inhibitors Affect Physical Properties of Arrowtooth Flounder and Walleye Pollock Surimi

Abstract
The effects of protease inhibitors from potato, bovine plasma and egg white on the punch, torsion and color tests of arrowtooth flounder and pollock surimi were determined. At 2% addition, the inhibitors increased the strength of arrowtooth gels while variable results were found with pollock gels. Bovine plasma produced a gel with a yellow hue while the gel with potato inhibitor was darkest.
