Abstract To improve the gel properties of freezing eel surimi, and increase its economic value, this anticle reserched the form of freezed eel surimi through mensuring the change of protein in the freezing eel producing by SDS-PAGE. The results indicate that Transglutaminase is important in the gelation process of the freezed eel surimi, and different concentration of Transglutaminase can en- hance the breaking force, sunken depth, and gel strength, but without obvious effect on color and whiteness. In condition of the optimal Transglutaminase concentration at 0.5%, the gel intension of freeze eel surimi was 550.4 g·cm, above 3 times of the comparative sample. Electron microscope analyse indicate that the addition of TGase can cause freezed eel surimi forming dense and uniform gel network structure.
