| 中文摘要: |
| 对海州湾近岸长蛸肌肉、肝胰脏和生殖腺3种组织的营养成分进行了分析。结果表明，3种组织中粗蛋白含量为13.1%~14.7%，其中肌肉＞肝胰脏＞生殖腺，肌肉干基粗蛋白含量比生殖腺中高6.69%（P<0.05）；粗脂肪含量均较低（0.9%~1.2%），生殖腺＞肝胰脏＞肌肉；3种组织均含18种氨基酸，肌肉、肝胰脏和生殖腺中EAA/TAA值分别为41.06%、40.34%和46.23%，EAA/NEAA值分别为69.67%、67.62%和89.84%，氨基酸组成符合FAO/WHO（1973）参考模式标准；肌肉中多不饱和脂肪酸(PUFA)占脂肪酸总量的519%，其中，C22∶6(DHA)、C20∶5(EPA)和C20∶4(AA)占PUFA总量的80.5%；肌肉中Fe和Zn两种微量元素含量较高，分别为6.07和5.95 mg/kg。 |

| The main nutrients in the muscle, hepatopancreas， and gonade of Octopus variabilis were determined, and the amino acid, fatty acid， and mineral elements were also analyzed and evaluated. The results showed that the content of crude protein in the three tissues was 13.1%~14.7%, among which the highest content was found in dry muscle (6.69% higher than in gonad) (P<0.05). The content of crude fat in the three tissues was low and ranged from 0.9% in muscle to 1.2% in gonad. There were 18 kinds of amino acids found in three tissues. The ratio of EAA/TAA in muscle, hepatopancreas, and gonade was 41.06%, 40.34%, and 46.23%, respectively, which accorded with the amino acids mode recommended by WHO/FAO (1973). PUFA in muscle accounted for 51.9% in total fatty acids, among which C22∶6(DHA), C20∶5(EPA) and C20∶4(AA) in total accounted for 80.5%. The content of Fe and Zn was relatively high in the muscle tissue and amounted to 6.07mg/kg and 5.95mg/kg respectively. In general, the nutrients in O. ariabili muscle were rich and ideal as a food source of human beings |
