摘要: 为了探讨半番鸭肌肉营养品质特性,对大型白羽半番鸭的胸肌肉常规营养成分、氨基酸和脂肪酸组分进行测定,并对其蛋白质营养价值做出评价。结果显示:大型白羽半番鸭胸肌水分含量为75.57%,粗蛋白质为21.79 %,粗脂肪为0.96 %,粗灰分为1.33 %,胸肌氨基酸总量为202.37 mg/g,必需氨基酸为83.20 mg/g,鲜味氨基酸为72.50 mg/g;氨基酸评分(AAS)和化学评分(CS)均表明:第一限制性氨基酸是蛋+胱氨酸,第二限制性氨基酸是缬氨酸;脂肪酸组分中不饱和脂肪酸和饱和脂肪酸比为1.22;雄性鸭与雌性鸭间胸肌谷氨酸和脂肪酸C16:0差异均显著,脂肪酸C18:2差异极显著。研究表明:大型白羽半番鸭肌肉具有蛋白质、氨基酸含量高,脂肪含量低的营养特性。

Abstract: In order to study the characters of meat quality of white-plumage mule duck, the nutritional components, the content of amino acids, the content of fatty acids and the protein nutritive value in the chest muscle of large white-plumage mule ducks were analyzed and evaluated. The results showed that the contents of moisture, crude protein, crude fat and crude ash in the chest muscle were 75.57 %, 21.79 %, 0.96 % and 1.33 %, respectively. And the total amino acid (TAA), essential amino acids(EAA), delicious amino acids were 202.37 mg/g, 83.20 mg/g and 72.50 mg/g, respectively. According to the amino acids score (AAS) and the chemical score (CS), the first limiting amino acid was Met + Cystine and the second was Valine. The ratio of unsaturated acids to saturated acid was 1.22. There were significant differences in glutamic acid and fatty acid C16:0 between the female and male ducks and extremely significant differences in fatty acid C18:2. In conclusion, large white-plumage mule duck was characterized by high content of protein and amino acid as well as low content of fat.
