摘要: 为了分析盐田汪子生态养殖硬壳蛤可食部位的营养成分及营养价值,对其基本营养成分、氨基酸、脂肪酸及矿物质等指标进行了测定。结果表明,硬壳蛤可食部位水分含量为86.37%,干基中蛋白质、脂肪、灰分质量分数分别为66.92%、6.21%、16.96%;共检出21种脂肪酸,包括10种饱和脂肪酸(SFA)、4种单不饱和脂肪酸(MUFA)和7种多不饱和脂肪酸(PUFA),其中不饱和脂肪酸含量约占52.88%,EPA和DHA的总量占PUFA的65.10%,占脂肪酸含量的27.18%;检测出了16种氨基酸,其中鲜味氨基酸含量约占总氨基酸含量的40.82%,EAA/TAA为35.79%,EAA/NEAA为55.70%,且富含矿物质Na、Ca、K、Mg等。可见硬壳蛤具有较高的营养价值。

Abstract: In this paper, the basic nutrients, amino acids, fatty acids and minerals of Mercenaria mercenaria were determined and analyzed. The results showed that the moisture content of the M. mercenaria was 86.37%, and the content of protein, fat and ash in the dry base were 66.92%, 6.21% and 16.96% respectively. A total of 21 fatty acids were detected, including 10 saturated fatty acids(SFA), 4 monounsatura-ted fatty acids(MUFA)and 7 polyunsaturated fatty acids(PUFA). The content of unsaturated fatty acid was 52.88% of the total fatty acids. The content of EPA and DHA was 65.10% of the PUFA, 27.18% of the total fatty acids. 16 amino acids were detected. The content of delicious amino acid was about 40.82% of the total amino acids. The EAA/TAA was 35.79% and the EAA/NEAA was 55.7%. The contents of Na, Ca, K, Mg were rich. In summary, the nutritional value of the M. mercenaria was high.

Key words: Mercenaria mercenaria, fatty acid, amino acid, nutritional value, evaluation
