摘要

对从印度西南海岸（阿拉伯海）捕捞的深海泥虾（Solenocera hextii）和铲鼻龙虾（Thenus unimaculatus）的脂肪酸图谱进行了评估和比较。棕榈酸和油酸分别是龙虾和虾类的主要饱和脂肪酸和单不饱和脂肪酸。单刺T.unimaculatus含有更高浓度的C20-22n-3多不饱和脂肪酸，如二十二碳六烯酸和二十碳五烯酸。与泥虾相比，铲鼻龙虾的n-3/n-6多不饱和脂肪酸比率更高（大于4），多不饱和/饱和脂肪酸（>1.2）和低胆固醇/高胆固醇比率（>2）也明显更高。较低的血栓形成性（≤0.5）和动脉粥样硬化形成性（<1.0）指数表明，单刺T.unimaculatus是人类营养理想的海洋物种。

Deep-sea mud shrimp and shovel-nosed lobster from the Arabian Sea as prospective sources of long-chain polyunsaturated fatty acids

Fatty acid profile of deep-sea mud shrimp (Solenocera hextii) and shovel-nosed lobster (Thenus unimaculatus) harvested from south-west coast (Arabian Sea) of India were evaluated and compared. Palmitic and oleic acids were the principle saturated fatty acids and monounsaturated fatty acids, respectively in lobster and shrimp species. T. unimaculatus contained greater concentrations of C20-22 n-3 polyunsaturated fatty acids, such as docosahexaenoic acid and eicosapentaenoic acid. Higher n-3/n-6 polyunsaturated fatty acid ratio (greater than 4) in addition to considerably greater polyunsaturated/saturated fatty acid (>1.2) and hypocholesterolaemic/hypercholesterolaemic ratio (>2) were recorded in shovel-nosed lobster compared to the mud shrimp. Lesser thrombogenicity (≤0.5) and atherogenicity (<1.0) indices recognised T. unimaculatus as a desirable marine species for human nutrition.
