雪山草鸡氨基酸组成与营养价值研究

[目的]评价雪山草鸡的营养价值。[方法]以雪山草鸡为材料,对各种氨基酸的含量及组成进行分析,并评价其营养价值。[结果]雪山草鸡肌肉中氨基酸含量占蛋白质含量的95.34%,且种类齐全,8种人体必需氨基酸的含量达1.096 g/kg。鲜味氨基酸、甜味氨基酸和芳香族类氨基酸占总氨基酸的质量分数分别为24.97%、17.86%和7.07%,各种人体必需氨基酸种类齐全且比例均衡,比值系数分(SRC)为76.91。在各种人体必需氨基酸中,第一限制氨基酸为甲硫氨酸+半胱氨酸。[结论]该研究可为雪山草鸡进一步开发利用提供科学依据。

Study on the Amino Acid Composition and Nutritional Value of Xueshan Chicken

[Objective] The research aimed to evaluate the nutritional value of Xueshan chicken.[Method] Using Xueshan chicken as test materials,the content and composition of its amino acids were analyzed.And its nutritional value was evaluated.[Result] The content of amino acids in the muscle of Xueshan chicken took 95.34% of protein content and the kinds of amino acids were rich.The content of 8 kinds of human essential amino acids reached 1.096 g/kg.The mass fraction of flavor amino acids,sweetness amino acids and aromatic amino acids in total amino acids were 24.97%,17.86% and 7.07% respectively.All kinds of human essential amino acids were rich and balanced,score of ratio coefficient(SRC) was 76.91.Among all kinds of human essential amino acids,the first limited amino acid was Met + Cys.[Conclusion] The research could provide scientific basis for future development and utilization of Xueshan chicken.
