【摘要】：研究选用200只1日龄健康大围山微型鸡(公母各半),在相同条件下饲养,于150日龄进行屠宰试验,对肌肉肉质性状和肌苷酸含量进行测定,比较大围山微型鸡肌苷酸含量与肉品质常规指标的差异及相关性。研究表明:母鸡腿肌pH_(24 h)显著高于胸肌(P0.05);公鸡胸肌L~*值显著低于母鸡(P0.05);公鸡腿肌a~*值极显著高于母鸡腿肌(P0.01);公鸡胸肌和腿肌剪切力均显著高于母鸡(P0.05);公鸡胸肌粗脂肪含量极显著低于母鸡(P0.01),母鸡腿肌粗蛋白含量极显著高于公鸡腿肌(P0.01),公鸡胸肌粗灰分含量显著低于母鸡(P0.05);母鸡胸肌和腿肌肌苷酸含量均显著高于公鸡(P0.05);相关性分析显示,胸肌和腿肌肌苷酸含量均与pH_(45 min)、p_H(24 h)、a~*值、剪切力、粗蛋白和粗脂肪呈正相关;与L~*值、b~*值、失水率、蒸煮损失率、粗灰分均呈负相关。
[Abstract]:200 1-day-old healthy Daweshan miniature chickens (male and female) were bred under the same conditions and slaughtered at 150 days of age. The meat quality and inosine content were measured.The difference and correlation between inosinic acid content and meat quality were compared.The fat content of hens was significantly lower than that of hens P0.01g, the content of crude protein of hens leg muscle was significantly higher than that of hens leg muscles, the content of crude ash of pectoralis muscle of female chickens was significantly lower than that of hens P0.05.The contents of inosine in breast and leg muscles of hens were significantly higher than those of P0.05hens, and the correlation analysis showed thatThe contents of inosinic acid in pectoralis and leg were positively correlated with the value of pH_(45, shear stress, crude protein and crude fat, but negatively correlated with the value of pH_(45 *, water loss rate, cooking loss rate and crude ash content.
