Freeze-thaw cycling led to decreased values for water holding capacity (WHC), gel strength and gel texture with all surimi and fish-meat gels. Both PM surimi and fish-meat gels had greater WHC and whiteness than those of RA grade. PM was more comparable to FA following freeze-thaw abuse. Although still better than RA, PM fish-meat gels showed a loss of cutting strength, hardness, breaking force and deformation. Texture analysis of gels showed that FA gel had more favorable chewiness, springiness, cohesiveness and brittleness. Overall, PM fish-meat gels were comparable to Alaska pollock FA fish-meat gels with respect to freeze-thaw stability. Keywords : Alaska pollock, Fish-meat gels, Pagrus major, Red sea bream, Surimi
