【摘要】 为了探明脆肉鲩(脆化饲养法)肉质脆化的机理,对普通草鱼(常规饲养法)和脆肉鲩的肝胰脏进行预处理,用毛细管气相色谱法对其游离氨基酸的组成和含量进行测定.结果表明普通草鱼和脆肉鲩的肝胰脏游离氨基酸组成相同,但含量差异显著,100g鲜样中游离氨基酸总含量分别为194.11mg和373.23mg,游离必需氨基酸总含量分别为82.62㎎和191.55mg.这种变化说明在草鱼的饲养过程中,改变其食物组成导致了草鱼肝胰脏游离氨基酸含量的改变.更多还原

【Abstract】 After pretreating the hepatopancreas of two groups of fishes- common grass carp (raised in routine) and grisped grass carp (raised in special method),then measure the composition and content of FAA in capillary gas chromatography.The result shows that the composition of FAA in the hepatopancreas between ordinary grass carp and grisped grass carp is the same,but the content of them is significantly different.The TFAA is respectively 194.11 mg/100 g fresh sample and 373.23 mg/100 g fresh sample.The TFEAA is respectively 82.62 mg/100 g fresh sample and 191.55 mg/100 g fresh sample.更多还原
