摘要: 采用通用方法分析金鲳鱼的营养成分,评价其营养价值,为金鲳鱼的综合利用提供参考。结果显示:金鲳鱼含16种常见氨基酸,其中7种是人体必需氨基酸。第一限制性氨基酸为色氨酸(Trp),第二限制性氨基酸为蛋氨酸(Met),必需氨基酸比例比较均衡,符合WHO/FAO的标准。金鲳鱼中不饱和脂肪酸(UFA)含量显著高于饱和脂肪酸(SFA)含量;单不饱和脂肪酸总量高于多不饱和脂肪酸总量,其中棕榈酸和油酸含量最高;富含亚油酸、DHA和EPA。综上,金鲳鱼营养丰富,具有较好的食用价值、保健作用和综合开发利用价值。Abstract: Nutritional components of the golden pompano were tested in routine methods in order to evaluate its nutritive value and offer basic data for multipurpose use.The results showed that 16 kinds of amino acids were found in the golden pompano, and 7 kinds of amino acids were essential for human needs.According to amino acid scores (AAS) and chemical scores (CS) , the first limited amino acid was Trp and the second limited amino acid were Met.The ratio of essential amino acids was equalization.The content of unsaturated fatty acids (UFA) was higher than the content of saturated fatty acids (SFA) .The content of cetylic acid and oleic acid were the highest.Besides, the contents of linoleic acid, EPA and DHA in fatty acids were rich.It was indicated that golden pompano was one of the fishes with good edible value and nutritive value and health benefits.It was worthy of exploitation and utilization.
