摘　　要：对龙虎斑鱼的肌肉进行营养成分分析和肉质评价,结果表明,龙虎斑鱼新鲜肌肉中粗脂肪质量分数4.18%,粗蛋白质量分数17.05%,粗灰分质量分数1.24%,水分质量分数80.19%。肌肉蛋白质中共检测出氨基酸种类有17种,占新鲜肌肉样品的质量分数为17.88%;7种必需氨基酸(EAA)占新鲜肌肉样品的质量分数为7.79%,占氨基酸总量的43.57%;4种鲜味氨基酸(DAA)占新鲜肌肉样品的质量分数为6.17%,占氨基酸总量的34.51%;必需氨基酸指数(EAAI)为101.35,其氨基酸组成比例符合FAO/WHO标准。新鲜肌肉中共检测出脂肪酸种类有14种。其中7种饱和脂肪酸(SFA)占总脂肪酸的质量分数为47.29%;4种单不饱和脂肪酸(MUFA)占总脂肪酸的质量分数为18.86%;3种多不饱和脂肪酸(PUFA)占总脂肪酸的质量分数为33.86%,DHA质量分数占脂肪酸总量的30.24%。龙虎斑鱼营养价值较高,海鲜味浓郁。Muscle nutrients of Pearl Gentian grouper （Epinephelus fuscoguttatus ♀ ×E. lanceolatus ♂）were analyzed and evaluated in this study. Results showed that the content of lipid in fresh muscle ofPearl Gentian grouper was 4.18%,and the content of crude protein, crude ash and moisture was17.05%,1.24% and 80.19%. 17 kinds of amino acid were detected from the fresh muscle,The amountof hydrolytic amino acids in the total amino acids of the muscle of the fresh weight was 17.14%;Thecontent of essential amino acids （EAA） was 7.79%, which make up 43.57% of the total amino acids.The content of delicious amino acids （DAA） was 6.17%,accounting for 34.51% of the total amino acids.Essential amino acid index （EAAI） was 101.35,The amino acids composition ratio accorded with thestandard of FAO/WHO. 14 fatty acids were found in the fresh muscle. The saturated fatty acid（SFA）,monounsaturated fatty acid（MUFA）,and polyunsaturated fatty acid（PUFA） was 47.29%,18.86%and33.86%. DHA was accounting for 30.24% of total fatty acids. Therefore,Pearl Gentian grouper （Epinephelus fuscoguttatus ♀ ×E. lanceolatus ♂） is culture fish with a higher nutrition value and richer eafood taste.
