摘　　要：利用梭子蟹池塘人工养殖过程中剔除的雄蟹制成软壳蟹(体重为65~70 g),并分析了其营养组成,结果显示:(1)蟹体中水分、粗脂肪、粗蛋白和灰分含量分别为87.02%、4.72%、6.25%和3.20%;(2)蟹体中富含多不饱和脂肪酸(PUFA),其总含量(ΣPUFA)占总脂肪酸的25.40%,其中,DHA、EPA和ARA的含量分别为14.84%、4.67%和1.86%;(3)蟹体中共检测到18种氨基酸,按湿重计,蟹体中必需氨基酸(EAA)含量和非必需氨基酸(NEAA)含量分别为26.77 mg·kg^-1和44.74 mg·kg^-1,总氨基酸(TAA)含量为71.51 mg·kg^-1,EAA/NEAA比值为0.60,EAA/TAA比值为0.37;(4)蟹体中富含Ca、P、K、Na、Mg、Fe、Zn等多种对人体有益的微量元素,其中Na和Ca含量最高,按湿重计,其含量分别为4522.97 mg·kg^-1和3450.35 mg·kg^-1;蟹体中含有微量的重金属元素,含量最高的为Cu元素也仅1.23 mg·kg^-1。整体上,本研究认为利用池塘人工养殖梭子蟹雄体生产的软壳蟹是一种营养丰富、健康安全的食品,具有良好的发展潜力。In this study,soft-shelled crabs(65-70 g in weight)were made from male crabs removed during artificial culture in Portunus trituberculatus ponds,and their nutritional composition was analyzed.The results showed that the contents of water,crude fat,crude protein and ash were 87.02%,4.72%,6.25% and 3.20% respectively.The crab body was rich in polyunsaturated fatty acids(PUFA),which accounts for 25.40% of the total fatty acids.the contents of DHA,EPA and ARA were 14.84%,4.67% and 1.86% respectively.Eighteen kinds of amino acids were detected in crabs,according to wet weight,the contents of essential amino acids(EAA)and non-essential amino acids(NEAA)were 26.77 mg·g^-1 and 44.74 mg·g^-1,respectively.The contents of total amino acids(TAA)were 71.51 mg·g^-1,the EAA/NEAA ratio was 0.60,and the EAA/TAA ratio was 0.37.Crab body was rich in Ca,P,K,Na,Mg,Fe,Zn and other trace elements which were beneficial to human body.Among them,Na and Ca contents were the highest,which were 4522.97 mg·kg^-1 and 3450.35 mg·kg^-1 respectively by wet weight.Crab body contained trace heavy metal elements,the highest content of Cu was only 1.23 mg·kg^-1.On the whole,this study considers that the soft-shelled crab produced by the male of P.trituberculatus cultured in ponds is a nutritious,healthy and safe food with good development potential.
