摘要: 试验选取中国西门塔尔公牛的冈上肌、背最长肌、腰大肌和半腱肌4个部位,分别对其进行物理指标(蒸煮损失、剪切力、pH及肉色)、营养品质(脂肪、蛋白质和水分含量)的测定及感官评定(嫩度、多汁性、风味)。结果表明,综合物理指标、营养物质含量和感官评分结果来看,以腰大肌肉质好,而半腱肌较差,水分含量和肉色红度值在各部位间没有显著差异(P>0.05),其他指标则存在显著差异(P<0.05),且某一种品质与多个客观指标有关,结合客观指标和感官试验才能更合理的评定牛肉品质。

Abstract: The longissmus doris,semitendinous muscle,psoas major muscle and semitendinosus of Simmemtal male calf was chosen and analyzed about myoglobin,shear force,pH,color,protein ,fat,water holding capacity,tenderness,juiciness and flavor. The results indicated that psoas major muscle was the best and semitendinosus was the worst by considering the data of both physical,nutrition and photographic assessment. The differences of water holding capacity and redness was not remarkable(P>0.05),and the differences of others were remarkable(P<0.05).It was more advisability by combining photographic assessment and objective indicators.
