【摘要】：以清溪花鳖和中华鳖日本品系为研究对象,对鳖雌雄肌肉和裙边水分、粗蛋白、粗脂肪、灰分、矿物质元素含量及氨基酸、脂肪酸组成进行分析。结果表明:1)清溪花鳖和中华鳖日本品系雌雄肌肉的粗蛋白含量分别为18.46%、17.25%、19.17%、18.83%,裙边为21.00%、22.31%、24.89%、20.07%,2种鳖雌雄肌肉的粗脂肪含量分别为1.07%、0.96%、1.17%、1.05%,裙边为0.23%、0.32%、0.30%、0.27%;2)清溪花鳖和中华鳖日本品系雌雄肌肉的必需氨基酸指数分别为93.92、92.52、91.89、93.12,说明2种中华鳖的肌肉营养丰富,均为良好蛋白源,肌肉中必需氨基酸/氨基酸总量分别为37.10%、36.67%、36.48%、36.76%,裙边中必需氨基酸/氨基酸总量分别为17.74%、19.73%、17.80%、17.81%;3)清溪花鳖和中华鳖日本品系雌雄肌肉中多不饱和脂肪酸含量丰富,二十碳五烯酸+二十二碳六烯酸的含量分别为14.98%、13.97%、16.20%、19.22%,中华鳖日本品系雌雄肌肉中二十碳五烯酸+二十二碳六烯酸的含量要高出清溪花鳖约3%。
[Abstract]:The contents of water, crude protein, crude fat, ash, mineral elements, amino acids and fatty acids in male and female muscles of Trionyx sinensis (Trionyx sinensis) and Japanese strain of Trionyx sinensis (Trionyx sinensis) were studied. The results were as follows: 1) the crude protein contents of female and male muscles of Qingxi and Chinese soft-shelled turtle lines were 18.46%, 17.25%, 19.17%, 18.83%, 21.00%, 22.31%, 24.89%, 20.07%, respectively, and their skirt edges were 21.00%, 22.31%, 24.89%, 20.07%, respectively. The crude fat contents of the muscles of the two species were 1.07%, 0.96%, 1.17%, 1.05%, 0.23%, 0.32%, 0.30%, 0.27%, respectively, and their skirt edges were 0.23%, 0.32%, 0.30% and 0.27%, respectively. 2) the essential amino acid index of male and female muscles of Qingxi and Chinese soft-shelled turtle strains were 93.92, 92.52, 91.89 and 93.12, respectively, indicating that the two species of soft-shelled turtle were rich in muscle nutrition and were good protein sources. The ratio of essential amino acid to amino acid in muscle was 37.10%, 36.67%, 36.48%, 36.76%, respectively. The ratio of essential amino acid / amino acid in skirt was 17.74%, 19.73%, 17.80%, 17.81%, respectively. 3) the polyunsaturated fatty acids in the muscles of Qingxi and Chinese soft-shelled turtle were rich, and the content of eicosapentaenoic acid 22 carbon hexaenoic acid was 14.98%, 13.97%, 16.20%, 19.22%, respectively. The content of eicosapentaenoic acid 22 carbon hexaenoic acid in the muscle of Japanese strain of Trionyx sinensis was about 3% higher than that of Qingxi Trionyx sinensis.
