摘要： The physicochemical properties, Ca2+-ATPase activity, and surface hydrophobicity of grass carp myobrillar with different cryoprotectants (0.5 % irradiated degraded KGM, 0.5 % beta-glucanase KGM hydrolysate, 8 % sucrose-sorbitol (1:1 w/w)) were investigated. The molecular weight analysis showed that the irradiated degraded KGM and beta-glucanase KGM hydrolysate were 1.209 x 10(4) and 2.093 x 10(4) Da, respectively. The solubility, Ca2+-ATPase activity, and total and reactive sulfhydryl (SH) content of treatments containing KGM hydrolysates were higher than other treatments during frozen storage. Addition of KGM hydrolysates could effectively prevent the increase of surface hydrophobicity. The gel strength and whiteness of surimi showed that the addition of KGM hydrolysates in this experiment resulted in surimi with comparable quality.
