2.8.Peroxide value
Gel samples (0.5 g) were mixed with 25 ml of a solution of glacial acetic acid and chloroform (3:2 v/v) in a conical flask,and then 1 ml of saturated potassium iodide was added.The mixture was kept in the dark for about 10 min,and then 30 ml of distilled water and 1 ml of freshly prepared 1% starch were added.After shaking,the samples were titrated with 0.01 M sodium thiosulfate.The peroxide values were expressed in units of meq/kg of sample (Egan,Kirk,& Sawyer,1981).
2.9.Statistical analysis
All analyses were run in triplicate for each replicate (n = 2*3).Results are reported as mean values of six determinations ± standard deviation (SD).Analysis of variance was performed by ANOVA procedures (SPSS 12.0 for Windows).Differences among the mean values of the various treatments and storage periods were determined by the least significant difference (LSD) test,and the significance was defined at P < 0.05.
3.Results and discussion
3.1.Proximate composition of grass carp muscle
Proximate analysis showed that grass carp muscle contains 18.95 ± 0.53% total protein,77.57 ± 0.37% moisture,1.83 ± 0.12% total lipid,and 1.19 ± 0.09% ash.Grass carp muscle has a low lipid,intermediate protein,and high moisture content,similar to previous reports (Bakir,Melton,& Wilson,1993).
3.2.Gel color
Color measurements of grass carp gels were shown in Table 2.Gels with chitosan exhibited higher L (80.08–83.68) than that of control (78.33) (P < 0.05).Significant differences of L values between gels containing high molecular weight chitosan (HC) or low molecular weight chitosan (LC) were not observed.However,L value increased significantly in gels when the mixture of high molecular weight chitosan and low molecular weight chitosan

所有分析运行式三份,为每个复制（每组2 * 3 ） .报告结果作为均值6裁定±标准偏差（标准差） .方差分析是由变异数分析程序（ SPSS的12.0适用于Windows ） .之间的差异平均值的各种处理和贮存期间确定了由至少显着性差异（迷幻剂）的测试,和意义的定义是在P < 0.05 .
3 .结果与讨论
3.1 .近因组成的草鱼肌肉
近因分析表明,草鱼肌肉包含18.95 ± 0.53 ％ ,总蛋白, 77.57 ± 0.37 ％ ,水分, 1.83 ± 0.12 ％ ,总脂,和1.19 ± 0.09 ％的灰.草鱼肌肉有一个低血脂,中间蛋白,高水分含量,类似以前的报告（ bakir ,麦尔登,与卫奕信, 1993年） .
3.2 .凝胶的颜色
颜色测量草鱼凝胶表2所示.凝胶壳聚糖展示了较高的升（ 80.08-83.68 ）比对照（ 78.33 ） ,性（ P < 0.05 ） .显着性差异升的价值观之间的凝胶含有高分子量壳聚糖（高等法院）或低分子量壳聚糖（立法会）不遵守.不过, L值显着增加时,凝胶的混合物高分子量壳聚糖和低分子量壳聚糖
