G' increased continually whereas C decreased due to cross-linking, indicating the formation of a highly elastic protein gel As vegetable oil concentration was increased. the G and G" values were decreased remarkably over the entire temperature range(Fig. 4). Keeping constant moisture level caused the increase of oil concentration and the decrease of protein concentration in gels. The lower protein concentration. the less elastic brown trout myofibril gel was formed(Lefevre et al. 1998). However, there were several studies showed the opposite conclusions that the modulus
