摘    要:试验选取10头24月龄的科尔沁公牛,对其肩肉、辣椒肉、板腱、脖肉、上脑、眼肉、外脊、里脊等部位肉进行营养成分、理化指标测定,并对数据进行统计分析。结果表明,粗蛋白质、粗脂肪、水分、嫩度、pH、a*值在不同部位间差异显著(P<0.05);反映肉色的L*值和b*值在不同部位间差异不显著(P>0.05);牛前部肉中肩肉和板腱的蛋白质、脂肪、水分和嫩度、肉色与中部高档部位肉很相近,无显著性差异(P>0.05),这些部位肉的价值有待进一步挖掘。

关 键 词:科尔沁牛  胴体部位肉  营养成分  嫩度  肉质

Abstract:Ten Horqin oxes with 24 months old were selected.The Nutrients,tenderness,pH and objective color of blade bolar,chuck tender,blade oyster,neck,highrib,ribeye,striploin,tenderloin were measured.By statistical analysis,the results showed that protein,fat,moisture,tenderness,pH and a*,respectively,were affected by different location(P<0.05).L* and b* were not affected by cuts(P>0.05).Protein,fat,moisture,tenderness and objective color of blade bolar and blade oyster were almost the same as middle high-grade cu...
Keywords:Horqin carcass  carcass cuts  nutrients  tenderness  meat quality
