We added sodium alginate (Na-Alg) from three kinds of the brown algaes to lizard fish myofibrils (Mf) and evaluated its effects on the state of water and the denaturation of Mf associated with dehydration.
Na-Alg had the effects of increasing the monolayer and multilayer water around Mf, decreasing water activity, and also had inhibitory effects on Mf dehydration. The inhibitory effects were markedly correlated with the state of the water.
These results suggested that Na-Alg inhibits dehydration-induced denaturation of Mf by stabilizing water around Mf.
