Impact of bambara groundnut protein isolate (BGPI) on autolysis and gel properties of surimi from lizard fish was investigated. As the levels of BGPI increased (0-3 %), breaking force, deformation and retention/ stability of myosin heavy chain (MHC) of modori gel markedly increased (P<0.05). Nevertheless, only 0.25% BGPI increased above parameters in kamaboko gel. A decreasing trend in whiteness and expressible moisture content of kamaboko gel was observed when the BGPI levels increased. Because of suitability of 0.25% BGPI in kamaboko gel, this level was selected for determination of microstructure and sensory analysis. Microstructure of kamaboko gel added with 0.25 % BGPI had a more compact structure than that without BGPI addition. Regarding sensorial properties, elasticity, texture and general acceptance of kamaboko gel added with 0.25% BGPI was significantly higher than control (P<0.05). Therefore, BGPI at an appropriate level could be a protease inhibitor to improve gel properties of kamaboko.
