Abstract:

The effects of different additives on surimi quality were investigated by measuring the activities of cathepsinB, H and L, pH, gel strength and folding flexibility, water-holding capacity and whiteness of grass carp surimi added withseveral saccharide and protein additives separately. Results indicated that different additives had different inhibitory effectson the activities of cathepsin B and L in grass carp surimi. Sucrose plus sorbite resulted in the greatest increase in surimi gelstrength. Grass carp surimi had the highest water-holding capacity upon the addition of potato starch. All additives testedexcept purple yam and refined kojac powder had no significant effect on surimi whiteness, but potato starch, sucrose plussorbite, refined kojac powder and collagen could remarkably enhance the folding efficiency of grass carp surimi.

Key words: grass carp, additive, surimi quality, cathepsin
