摘要: 采用生物化学方法测定和分析了野生黄唇鱼(Bahaba flavolabiata)肌肉和鳔的营养成分。黄唇鱼肌肉和鳔的营养成分都属于高蛋白、低脂肪类型。肌肉的必需氨基酸模式优于FAO/WHO的理想模式,氨基酸含量、必需氨基酸含量和鲜味氨基酸含量均较高,种类齐全。鳔的氨基酸组成较FAO/WHO的理想模式低,但其蛋白质含量高达35.90%,高于其他已报道的水产品,粗脂肪和粗灰分含量较低;氨基酸种类齐全且含量丰富,富含鲜味氨基酸;在氨基酸测定中发现了牛磺酸、γ-氨基丁酸、鸟氨酸和羟脯氨酸等4种具Abstract: Nutrition composition in muscle and air bladder of wild Bahaba flavolabiata was investigated. Results show that in the nutrition composition of muscle and air bladder there are high protein and low fat. In muscle, the composition of amino acids met the Food and Agriculture Organization of the Untied Nations/World Health Organization (FAO/ WHO) standard. The contents of amino acid,essential amino acid and flavour amino acid are relatively high with complete component type. In air bladder, the composition of amino acid is less than the FAO/ WHO standard, while its protein content of 35.90% was higher than that of other aquatic produces reported, and the contents of crude fat and crude ash are lower. The content of amino acid is high with complete component type, being rich in flavour amino acids. Four kinds of derived amino acids such as Tau,γ-GAba, Orn, and HYpro with important physiological functions were found in air bladder. The ratio of branch-chain amino acid to aromatic amino acid in muscle and air bladder was calculated closing the normal value of that in human. The contents of unsaturated fatty acids are relatively rich, with the ratio of 1.45 and 1.51 in terms of unsaturated fatty acids/saturated fatty acids separately. calcium,shodium,potassium magnesium,iron,copper and zinc were found which were essential for the human. The results indicate that muscle and air blader of B.flavolabiata are the high nutritive sea-food.
