| 以虹鳟(Oncorhynchus mykiss)、山女鳟(O.masou masou)及其杂交F1(虹鳟♀×山女鳟♂)为研究对象,分别进行了肌肉营养成分和肌肉质地测定。结果显示,(1)杂交F1肌肉粗脂肪含量显著低于双亲(P<0.05),含水率和粗蛋白含量介于双亲之间,其中含水率最高者为山女鳟,粗蛋白含量最高者为虹鳟,并且三者间差异显著(P<0.05);(2)杂交F1肌肉氨基酸总量、必需氨基酸总量、非必需氨基酸总量和鲜味氨基酸总量均显著高于双亲(P<0.05),其半必需氨基酸含量高于虹鳟,但低于山女鳟;(3)3种鱼肌肉营养品质评价结果表明,杂交F1肌肉必需氨基酸指数(77.77)明显高于虹鳟(63.67),略低于山女鳟(79.19);(4)杂交F1肌肉肉色(亮度、红度、黄度)和嫩度与双亲相比差异显著(P<0.05),按肉色和嫩度测定值由高到低排列依次为山女鳟>杂交F1>虹鳟。研究结果表明,杂交F1继承了山女鳟肉质优良的特性,肌肉品质优于虹鳟,这为虹鳟和山女鳟杂交育种提供了参考。 |

| This study was conducted to analyze the flesh composition and flesh texture of Oncorhynchus mykiss,O. masou masou and their hybrid F1 (O.mykiss♀×O.masou masou ♂ ). The results showed that,(1) content of crude lipid of flesh was significant lower in crossbreed F1 than in its parents (P<0.05),moisture of flesh was lower in crossbreed F1 than in O.masou masou,but higher than in O.mykiss (P<0.05),while crude protein was lower than in O.mykiss,but higher than in O.masou masou (P<0.05);(2) the total amino acid,essential amino acid,non-essential amino acid and total delicious AA of flesh were higher in crossbreed F1 than in their parents,while semi-essential amino acid was higher in crossbreed F1 than in O.mykiss and lower than in O.masou masou;(3) the muscle nutritional quality evaluation results of crossbreed F1 and the parents show that the EAA index of crossbreed F1 was 77.77,which was approaching that of O.masou masou (79.19) and significant higher than that of O.mykiss (63.67);(4) there are significant difference between crossbreed F1 and the parents (P<0.05) in flesh color and tenderness,the measured value of crossbreed F1 was higher than that of O.mykiss and lower than that of O.masou masou. All of results showed that the flesh quality of O.masou masou is better than that of O.mykiss,the flesh quality of crossbreed F1,inheriting the characteristics of O.masou masou,was much better than that of O.mykiss. |
