本文测定了花点石斑鱼和青石斑鱼肌肉中18种氨基酸的含量。测定结果表明:石斑鱼肌肉中氨基酸含量较高,花点石斑鱼肌肉中氨基酸总含量为764.98mg/g,青石斑鱼的为743.78mg/g,这两种石斑鱼肌肉的氨基酸总舍量中,人体的8种必需氨基酸含量之和分别为40.87%和41,99%;谷氨酸、天门冬氨酸,精氨酸、丙氨酸和甘氨酸等5种氨基酸系的鲜味物质的含量之和分别为45.03%和44.37%.石斑鱼肌肉所含必需氨基酸的比值与人体所需氨基酸的组成模式比较接近.所以,对人体来说,石斑鱼肌肉是一种营养价值较高的鲜美的蛋白源.最后,本文提出了石斑鱼必需氨基酸的组成模式。
In this paper, the determination of the 18 kinds of amino acids in the muscle of the spotted grouper and the green grouper. The results showed that the content of amino acids in muscle of grouper was higher, the total content of amino acids in the muscle of flower grouper was 764.98 mg / g, and that of blue grouper was 743.78 mg / g. The total amino acids In the rounding, the sum of the eight essential amino acids in the human body is 40.87% and 41.99%, respectively; and five kinds of amino acid-based umami substances such as glutamic acid, aspartic acid, arginine, alanine and glycine And the sum of the content is 45.03% and 44.37%, respectively.The ratio of essential amino acids contained in grouper muscle is close to the composition pattern of amino acids required by human body.Therefore, for the human body, grouper muscle is a nutritional value High and delicious protein source.Finally, this paper presents the compositional pattern of essential amino acids in grouper.
