| 摘 要： | 试验旨在分析乌珠穆沁草原饲养的黑安格斯牛肌肉氨基酸组成及其营养价值,为该品种的饲养、杂交繁育及肉品质评价提供基础数据。采集7头体重为500 kg±38 kg黑安格斯肉牛的里脊、臀肉、肩肉、眼肉、上脑、胸肉和米龙等部位肉样,测定其氨基酸含量与组成,并用FAO/WHO氨基酸模式进行营养价值分析。结果显示样品中水分平均含量68.73%,低于国家标准;粗脂肪平均含量为30.56%。并检测出17种氨基酸,鲜味、甜味和苦味氨基酸含量丰富,其与总氨基酸(TAA)含量的比值分别为25.8%、32.7%和41.6%。必需氨基酸(EAA)含量、EAA/TAA、EAA/NEAA及EAA评分均超过FAO/WHO氨基酸模式。在所有测定样品中,眼肉、里脊和上脑氨基酸含量较高,氨基酸组成丰富。综上所述,乌珠穆沁草原饲养的黑安格斯牛肉氨基酸组成丰富,含量较高,能够满足人体营养需要,属于优质蛋白质。

| Abstract: | This experiment was aimed to analyze the amino acids composition and nutrient value of Black Angus raised in Ujinmqin grassland and provide basic data for feeding,cross breeding,and meat quality evaluation.Highrib,tenderloin,ribeye,nates meat,topside,shoulder clod and brisket samples were collected from seven Australian imported Black Angus raised in Ujinmqin grassland with 500 kg?38 kg body weight.The content and composition of amino acids were determined and then nutritent value were analyzed using FAO/WHO amino acids pattern.The results showed that the moisture and crude fat of samples were 68.73% and 30.56%.There were total 17 kinds of amino acids were determined in the samples and UAA,SAA and BAA were abundant.The ratios of these three abundant amino acids to total amino acid (TAA) were 25.8%,32.7% and 41.6%,respectively.The EAA content,EAA/TAA,EAA/NEAA and the EAA scores were all higher than FAO/WHO amino acids pattern.The amino acids content of ribeye,tenderloin and highrib were higher than that of other parts of muscle.In conclusion,the meat of Black Angus raised in Ujinmqin grassland had abundant composition and high content of amino acids,which were able to provide enough nutrient elements for human beings. |
