摘　　要：测定了中华鳖肌肉和油脂块的水分、蛋白质和脂肪含量、肌肉的矿物质和氨基酸含量、肌肉和油脂块的脂肪酸组成。结果表明:肌肉的蛋白质和脂肪含量分别为 1 8.2 1 %和 1.2 3 %,油脂块的脂肪含量为 86.72 %;肌肉中微量元素含量丰富,其中铁和铬含量分别为 3 80.1 3mg/kg和 1.0 8mg/kg;肌肉的必需氨基酸和鲜味氨基酸含量分别占氨基酸总量的 4 6.94 %和 4 5.4 5%,其中鲜味谷氨酸和天门冬氨酸含量最高,分别为 1 1.90 %和 7.94 %;肌肉和油脂块中高度不饱和脂肪酸含量分别占脂肪酸总量的3 0.1 8%和 2 4.96%,其中肌肉的EPA和DHA含量分别高达 9.93 %和 9.1 2 %。在上述研究结果的基础上。Experiments were carried out to study on the content of moisture, crude protein and lipid of muscle and fatty block, and of mineral element and amino acid of muscle, and on the fatty acid composition of muscle and fatty block in Chinese soft shelled turtles (Trionyx sinensis ). Results showed that protein and lipid content in muscle were 18.21% and 1.23% respectively, and lipid content of fatty block was 86.72%. It was found that there were rich trace mineral elements of important physiological functions in muscle, in which iron and chromium content were 380.13 mg/kg and 1.08 mg/kg. The essential amino acids and delicious amino acids in muscle accounted for 46.94% and 45.45% of total amino acids respectively, in which glutamic acid and aspartic acid content were highest, reaching about 11.90% and 7.94%. The fatty acids of muscle and fatty block contained 30.18% and 24.96% of high unsaturated fatty acids, among which EPA (Eicosapentaenoil acid) and DHA (Docosaheraenoic acid) content were 9.93% and 9.12%. On the basis of above results, the nutrient value and health keeping value of turtle were confirmed.
