| 中文摘要: |
| 测定了养殖星斑川鲽肌肉中的蛋白质、脂类和灰分等生化组分，并计算了其比能值，分析了肌肉中构成蛋白质的16种常见氨基酸和主要脂肪酸含量。结果表明，星斑川鲽属高蛋白、低脂肪鱼类；肌肉氨基酸含量同其他鲆鲽鱼类相比，属中上等水平；必需氨基酸和呈味氨基酸的含量较高。肌肉蛋白中氨基酸的支/芳值为2.33。各类脂肪酸中，油酸（18∶1n）含量最高，其次为亚油酸（18∶2n6）和棕榈酸（16∶0）。星斑川鲽富含EPA和DHA，营养丰富且平衡良好，是值得推荐的优良养殖品种和优质食用鱼类。 |
| 英文摘要: |
| Muscle of cultured starry flounder Platichthys stellatus were analyzed for the content of protein, lipids, ash, amino acid, fatty acid, and other biochemical components. The results showed that starry flounder is a kind of fish with high protein and low lipid contents. And the total amino acid content was of medium level. However, the essential amino acid contents were of high level. The ratio of branched-chain and aromatic amino acids was 2.33 for juvenile starry flounder. Oleic acid (18∶1n) content was the highest of all fatty acids, and the contents of linoleic acid (18∶2n6) and palmitic acid (16∶0) were lower than oleic but higher than the other fatty acids. The fish was also rich in the EPA (20∶5n3) and DHA (22∶6n3), and had enriched and balanced nutrients, indicating that it is an excellent candidate for farming and is a nutritious seafood. |
