Abstract

The fatty acid composition in the hepatopancreas of the red king crab from the Barents Sea was studied. Polyunsaturated fatty acids dominated among the fatty acids analyzed (11 792 ± 592 μg/g, 45.3 ± 0.7% of the total fatty acid concentration). Saturated fatty acids and monounsaturated fatty acids were found in approximately equal proportions accounting for 7825 ± 454 μg/g (28.3 ± 0.4%) and 7661 ± 510 μg/g (26.4 ± 0.6%), respectively. Significant interannual and intersexual differences were found in the fatty acid profiles of the crabs studied. The crab size, shell age, and number of injured legs did not affect the fatty acid compositions in the hepatopancreas. The high concentrations of essential fatty acids belonging to the omega-3 and omega-6 classes indicate that the hepatopancreas of the Barents Sea red king crab could be used as a source of extraction of these valuable substances.

巴伦支海红帝王蟹肝胰腺中的脂肪酸组成

摘要

研究了来自巴伦支海的红帝王蟹的肝胰脏中的脂肪酸组成。在分析的脂肪酸中，多不饱和脂肪酸占主导（11 792±592μg/ g，占总脂肪酸浓度的45.3±0.7％）。发现饱和脂肪酸和单不饱和脂肪酸的比例大致相等，分别为7825±454μg/ g（28.3±0.4％）和7661±510μg/ g（26.4±0.6％）。在所研究的螃蟹的脂肪酸谱中发现了明显的年际和两性差异。螃蟹的大小，壳龄和受伤的腿的数量不影响肝胰腺中的脂肪酸组成。
