The transglutaminase(TGase) was added in the silver carp surimi to improve the quality.The effect of TGase concentration,handing time,handing temperature and pH on white degrees,hardness,springiness,cohesiveness and solubility was researched.The result showed that the addition of TGase at different concentrations could improve the hardness,springiness,cohesiveness of silver cap surimi gels distinctly without obvious effect on color and whiteness.The appropriate adding condition of TGase confirmed by orthogonal test was transglutaminase concentration 0.3%,handing time 60min,temperature 40℃ and pH7.5.SDS-polyacrylamide gel electrophoresis and solubility analyses indicated that myosin heavy chain(MHC) of silver carp surimi gels could form covalent cross-linking under the catalysis of TGase added.
