| Abstract: | 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. |
