| 摘 要： | 为评价新品种白金丰产鲫Carassius auratus Var.Pengzenensis♀×Cyprinus acutidorsalis Wan♂的含肉率和肌肉营养成分,选取体质量为(580.33±198.02)g的1龄白金丰产鲫进行分析,测定其含肉率、一般营养成分、氨基酸组成和脂肪酸组成。结果表明:白金丰产鲫含肉率为66.22%,肌肉中水分含量为79.90%,粗蛋白质含量为17.61%,粗脂肪含量为1.71%,灰分含量为1.13%;采用酸水解法共检测出17种氨基酸,其中必需氨基酸占氨基酸总量的39.50%,呈味氨基酸占总氨基酸含量的37.12%;必需氨基酸评价显示,白金丰产鲫的必需氨基酸评分均大于1,必需氨基酸组成符合FAO/WHO模式标准;共检测到23种脂肪酸,其中饱和脂肪酸(SFA)7种,不饱和脂肪酸(UFA)16种,不饱和脂肪酸(UFA)含量为70.09%,其中的多不饱和脂肪酸(PUFAs)含量为42.48%。研究表明,白金丰产鲫含肉率高,必需氨基酸含量丰富、组成合理,脂肪酸种类丰富,不饱和脂肪酸特别是高度不饱和脂肪酸含量高。

| Abstract: | The dressing rate,approximate nutrient composition,and composition of amino acid and fatty acid were determined in muscle of 1-year-old crucian carp hybrid Carassius auratus Var. Pengzenensis♀×Cyprinus acutidor-salis Wang♂ with body weight of (580.33±198.02)g to evaluate dressing rate and nutritional composition of the crucian carp hybrid. It was found that the fish had dressing rate of 66.22%, moisture of 79.90%, crude protein content of 17.61%,crude fat content of 1.71% and ash content of 1.13% in the muscle. A total of 17 amino acids were detected by acid-hydrolysis method, with essential amino acids of 39.50%, and delicious amino acids of 37.12% in the total amino acids. The essential amino acid scores analysis revealed that the crucian carp hybrid had essential amino acid scores of over 1,the essential amino acid composition being in line with the FAO / WHO mod-el standard. In this study,23 fatty acids were detected, including 7 saturated fatty acids (SFA), 16 unsaturated fatty acids (UFA), 70.09% of unsaturated fatty acids(UFA), and 42.48% of polyunsaturated fatty acids(PU-FAs). The findings indicated that the crucian carp hybrid as a new variety was featured by high dressing rate,rich and reasonable composition in essential amino acids,rich in fatty acid,and high content of unsaturated fatty acids, especially highly unsaturated fatty acid content. |
