The more elastic brown trout myofibril gel was formed with the higher protein concentration(Lefevre et al. 1998). Along with water content increasing. the decreasing amount of myofi brillar protein could lead to a lower value for surimi with hy droxyl propyl methylcellulose(Chen& Huang, 2008). Therefore, the surimi paste with a higher oil concentration exhibited the lower G and G" values in Fig. 4. The increase of vegetable oil concentration could not compensate the weakenin effect of reduction of fish protein on the surimi gel network
