ABSTRACT The squat lobster Munida gregaria has been recognized as a potential resource in several countries. However, data about its composition and nutritional value are scarce. This study provides information about the nutrients and nutritional quality of M. gregaria meat. Meat yield, proximate composition, cholesterol content, and fatty acid (FA) and amino acid (AAs) profiles were analyzed, and nutritional quality indexes were estimated. The average meat yield was 9.93%. The yearly average of the proximate composition of the M. gregaria meat (g/100 g meat) was moisture = 77.6, protein = 13.7, lipids = 3.84, and ash = 2.19. The average annual cholesterol content was 6.60 mg/100 g. The predominant FA (%) was C20:5ω3 (23.6), followed by C18:1ω9c (20.9), C22:6ω3 (18.5), and C16:0 (16.3); the unsaturated fatty acids were 72.8% of the total FA. The main AAs (g/100 g protein) were glutamic acid (15.1), leucine (9.47), and aspartic acid (8.51). Regarding the nutritional quality, the polyunsaturated FA/saturated FA ratio (1.99), ω3/ω6 ratio (8.62), atherogenic index (0.26), thrombotic index (0.56), hypocholesterolemic/hypercholesterolemic ratio (4.07), and polyene index (2.58) showed that M. gregaria meat provides lipids that are beneficial to the human diet. Moreover, M. gregaria meat provides high-quality proteins, which are well balanced in their essential AAs composition.

蹲龙虾 Munida gregaria 肉的近似成分和营养质量 (Fabricius 1973)

摘要 蹲龙虾 Munida gregaria 已被多个国家认可为潜在资源。然而，关于其成分和营养价值的数据很少。本研究提供了有关 M. gregaria 肉的营养成分和营养质量的信息。分析了肉类产量、近似组成、胆固醇含量以及脂肪酸 (FA) 和氨基酸 (AAs) 谱，并估计了营养质量指标。平均产肉率为9.93%。M. gregaria 肉的近似组成（g/100 g 肉）的年平均值为水分 = 77.6、蛋白质 = 13.7、脂质 = 3.84 和灰分 = 2.19。年平均胆固醇含量为 6.60 毫克/100 克。主要的 FA (%) 是 C20:5ω3 (23.6)，其次是 C18:1ω9c (20.9)、C22:6ω3 (18.5) 和 C16:0 (16.3)；不饱和脂肪酸占总脂肪酸的 72.8%。主要的 AA（g/100 g 蛋白质）是谷氨酸 (15.1)、亮氨酸 (9.47) 和天冬氨酸 (8.51)。关于营养质量，多不饱和脂肪酸/饱和脂肪酸比 (1.99)、ω3/ω6 比 (8.62)、致动脉粥样硬化指数 (0.26)、血栓指数 (0.56)、低胆固醇/高胆固醇比 (4.07) 和多烯指数 (2.58)表明 M. gregaria 肉提供对人类饮食有益的脂质。此外，M. gregaria 肉提供了高质量的蛋白质，这些蛋白质的必需氨基酸组成非常平衡。和多烯指数 (2.58) 表明 M. gregaria 肉提供对人类饮食有益的脂质。此外，M. gregaria 肉提供了高质量的蛋白质，这些蛋白质的必需氨基酸组成非常平衡。和多烯指数 (2.58) 表明 M. gregaria 肉提供对人类饮食有益的脂质。此外，M. gregaria 肉提供了高质量的蛋白质，这些蛋白质的必需氨基酸组成非常平衡。
