The decrease in MHC in kamaboko gel was generally due to the polymerisation mediated by endogenous transglutaminase, whilst the degradation was dominant in modori gel. No differences in MHC band intensity were observed in gels added with ZnSO4 or ZnCl2 at levels up to60 mmol/kg. Nevertheless,at 80 mmol/kg concentration, MHC was much more retained in both kamaboko and modori gels.
