该研究测定了野生波纹唇鱼Cheilinus undulates肌肉的营养成分。结果显示, 波纹唇鱼肌肉(鲜样)的水分、粗蛋白、粗脂肪和粗灰分的含量分别为80.97%、18.38%、0.10%和0.49%。肌肉中含有18种氨基酸, 总量为15.70%(鲜重), 必需氨基酸含量占氨基酸总量的39.37%, 必需氨基酸的组成符合FAO/WHO的标准。氨基酸的支/芳值为2.5654, 接近正常人的支/芳值; 依据氨基酸评分(AAS)结果, 第一限制性氨基酸为苏氨酸(Thr), 第二限制性氨基酸为色氨酸(Trp); 必需氨基酸指数(EAAI)为68.46; 4种鲜味氨基酸(SAA)的总量为31.85%。脂肪酸中二十碳五烯酸(EPA) + 二十二碳六烯酸(DHA)的含量为21.86%。含有人体所必需的钠、钾、钙、镁、铁、铜、锌等元素, 表明波纹唇鱼具有较高的营养价值。

Nutritive composition in muscle of wild double-headed parrotfish Cheilinus undulates was investigated in this study. Results showed that the contents of moisture, crude protein, crude lipid, and crude ash in fresh muscle of C. undulates were 80.97%, 18.38%, 0.10% and 0.49%, respectively. A total of 18 kinds of common amino acid in the muscle was detected with the 15.7%(wet weight); the content of essential amino acids was 39.37% of the total ones, which met the Food and Agriculture Organization of the Untied Nations/World Health Organization (FAO/WHO) standard. The ratio of branch-chain amino acids to aromatic amino acids was 2.5654, close to the normal value of that in human. According to nutritive evaluation in amino acid score(AAS), the first limited amino acid was threonine (Thr), the second was tryptophane (Trp), and the value of essential amino acid index (EAAI) was 68.46. The total content of four smelled amino acids was 31.85%. The content of EPA + DHA in fatty acids was 21.86%。The elements of Na, K, Ca, Mg, Fe, Cu, Zn were found in muscle, which were essential for the human. In conclusion, this research indicated that C. undulates is a nutritive sea-food fish.
