| 摘 要： | 使用常规营养测试方法,测定尖鳍鲤的肌肉营养成分.结果表明,其水分含量为79.29(±1.54)％,粗蛋白含量为16.77(±0.31)％,粗脂肪含量为2.48(±0.1 1)％,粗灰分含量为1.54(±0.1 1)％.使用GC-MS(气相色谱-质谱联合)技术,对尖鳍鲤的肌肉脂肪酸成分进行分析,研究各组分脂肪酸占总脂肪酸的比重.结果表明,尖鳍鲤肌肉中共分离和鉴定出18种脂肪酸,其中饱和脂肪酸(SAF)8种,分别是2-己基-环丙烷辛酸、月桂酸、12-甲基十三烷酸、肉豆蔻酸、十五烷酸、棕榈酸、珠光脂酸和硬脂酸;单不饱和脂肪酸(MUFA)4种,占总脂肪酸的40.4％,分别是9-十六烯酸、9-十八烯酸、11-十八烯酸和11-二十碳烯酸;多不饱和脂肪酸(PUFA)6种,分别为9,12-十八碳二烯酸、11,14-二十碳二烯酸、α-亚麻酸、11,14,17-二十碳三烯酸、花生四烯酸和DHA,占总脂肪酸比重的17.0％.

| Abstract: | The nutritional components of muscle in Cyprinus acutidorsalis Wang were analyzed using ordinary standard methods. The results showed that contents of moistur , crude protein, crude fat, crude ash were 79.29(±1.54)%,16.77(±0.31)%, 2.48(±0.11)% and 1.54(±0.11)% in fresh muscle, respectively. The fatty acid composition of muscle in C.acutidorsalis Wang were analyzed through gravimetric method and tested by gas chromatogrphy-mass spectrometry(GC-MS) technology. The results showed that, 18 kinds of fatty acids were separated and determined. Among them, there were 8 kinds of saturated fatty acids (SAF) including cyclopropaneoctanoic acid, 2-hexyl, dodecanoic acid, tetradecanoic acid-12-methyl, etradecanoic acid, pentadecanoic acid, hexadecanoic acid, heptadecanoic acid and octadecanoic acid; there were 4 kinds of monounsaturated fatty acid (MUFA) including 9-hexadecenoic acid, 9-octadecenoic acid, 11-octadecenoic acid, 11-eicosenoic acid, accounting for 40.4% of the total fatty acids; there were 6 kinds of polyunsaturated fatty acids (PUFA) including 9,12-octadecadienoic acid, 11,14-eicosadienoic acid, 9,12,15-octadecatrienoic acid, 11,14,17 eicosatrienoate,eicosatetraenoic acid and docosahexaenoic acid, accounting for 17.0% of the total fatty acids. |
