• Resumen

  • The effects of organic salts (sodium (Na)-citrate, Na-gluconate, and Na-succinate) on the solubilization of myofibrillar proteins and the inhibition of autolysis of squid mantle muscle were investigated. All of the organic compounds dissolved myofibrils as NaCl did. Na-citrate showed the strongest ability with half dissolving at 0.06 M. Half dissolving by Na-gluconate, Na-succinate, and NaCl were 0.27, 0.21, and 0.27 M, respectively. Dissolving myofibrils by Na-citrate was not accompanied by the acceleration of autolysis. Na-citrate above 0.25 M almost completely inhibited the autolysis. The inhibition of autolysis by Na-gluconate and Na-succinate was much less than that of Na-citrate. Consequently, it was concluded that Na-citrate was the organic salt to dissolve squid myofibrils without inducing autolysis.
