摘要
对大眼金枪鱼、黄鳍金枪鱼和蓝鳍金枪鱼的营养成分进行对比评价。采用原子吸收分光光度计、高效液相色谱仪、氨基酸自动分析仪对金枪鱼腹部肌肉的蛋白质、脂肪、氨基酸、脂肪酸、矿物质及维生素的含量进行了对比分析。结果显示,金枪鱼的蛋白质含量较高而脂肪含量较低,氨基酸种类齐全,含有丰富的不饱和脂肪酸、多不饱和脂肪酸和EPA、DHA;富含人体必需常量元素和多种微量元素;维生素含量也较高,具有较高的营养价值和良好的开发利用前景。
The nutritional components of bigeye tuna, yellow-fin tuna and blue-fin tuna were studied and evaluated in this paper. The contents of protein,fat,amino acids,fatty aids,mineral elements and vitamin in tuna abdominal muscles were analyzed by atomic absorption spectrophotometer, HPLC, automatic amino acid analyzer. The results indicated that in the three kinds of tuna the contents of protein was higher but the contents of fat wa s low. Tuna contains variety of amino acid,meanwhile it was rich in unsaturated fattty acids,PUFA,EPA and DHA. It was rich for human in some necessary macroelements and multiple microelements in tuna. As to vitamin contents in the tuna,also had a higher content. Therefore,the three kinds of tuna could be considered to have higher nutritive value and great potential for the exploitation and utilization.
