摘要: 本研究对翘嘴鲌(Culter alburnus)、团头鲂(Megalobrama amblycephala)及其杂交子一代鲌鲂F1(C.alburnus♀×M.amblycephala♂)、子二代鲌鲂F2(self-crossing of C. alburnus♀×M. amblycephala♂)背部肌肉的营养成分进行了比较分析,并对其营养品质进行了评价与对比。结果显示:鲌鲂F1和F2肌肉的水分含量均显著低于父本团头鲂(P<0.05),粗蛋白含量则显著高于团头鲂(P<0.05),鲌鲂F1的粗脂肪含量显著高于鲌鲂F2和团头鲂(P<0.05)。4种鱼均检测出18种氨基酸,其中,鲌鲂F2的氨基酸总量(TAA)、必需氨基酸(EAA)、呈味氨基酸(DAA)、∑EAA/∑TAA、∑EAA/∑NEAA、氨基酸评分(AAS)、化学评分(CS)及必需氨基酸指数(EAAI)等均不同程度高于亲本及鲌鲂F1。4种鱼均检测出20种以上的脂肪酸,其中,鲌鲂F1的∑PUFA和∑EPA+DHA含量高于双亲,并显著高于鲌鲂F2(P<0.05),∑SFA:∑MUFA:∑PUFA比值为1:1.88:1.02,较双亲及鲌鲂F2更接近人体合理膳食的理想模式。综合分析,相较于双亲,鲌鲂F1具有高脂、高蛋白、高EPA+DHA和均衡的脂肪酸组成等营养价值特点,鲌鲂F2则具有低脂、高蛋白、均衡的氨基酸组成以及最优的食用品质。因此,鲌鲂F1和F2具有不同的营养品质特点,可满足消费者的不同需求,均具有良好开发利用前景。

Abstract: In this study, the nutritional components of the back muscles of topmouth culter (Culter alburnus) (Abbr. CA), blunt nose bream (Megalobrama amblycephala) (Abbr. MA), hybrid of (female C. alburnus) × (male M. amblycephala ) (Abbr. HF1) and self-crossing of hybrid of (female C. alburnus) × (male M. amblycephala) (Abbr. HF2) were analyzed, and their nutritional quality were also evaluated and compared. Results showed that moisture contents were significantly lower in HF1 and HF2 than that in MA (P<0.05), while their crude protein contents were significantly higher (P<0.05), and crude fat content in HF1 was significantly higher when compared with that in HF2 and MA (P<0.05). Eighteen kinds of amino acids were found in muscles from four kinds of fish with all of them higher in HF2 than HF1 and their parents, including the total amino acids (TAA), essential amino acids (EAA), delicious amino acids (DAA), ∑EAA/∑TAA, ∑EAA/∑NEAA, amino acids score (AAS), chemical score (CS) and essential amino acid index (EAAI) to some degree (specific). More than twenty kinds of fatty acids were found in muscles from four kinds of fish. The ∑PUFA and ∑EPA+DHA content of HF1 were higher than that in its parents, and were significant higher when compared with that of HF2. Furthermore, ∑SFA:∑MUFA:∑PUFA of HF1 was 1:1.88:1.02, which was closer to the ideal diet of human body than that of its parents and HF2. In general, HF1 had high nutritional value such as low moisture, high fat, high protein, high EPA+DHA and balanced fatty acids composition when compared with parents. In addition, HF2 had low moisture, low fat, high protein and balanced amino acids composition as well as the best edible quality. They all can provide high-quality aquatic protein for different demand of market and have good prospects for development and utilization.
