摘要: 以臀股二头肌为研究对象,比较分析黑色牛肉与正常色泽牛肉在理化性状和凝胶特性上的差异。结果表明:在化学成分方面,除水分含量有明显差异(P<0.05)之外,粗蛋白含量、粗脂肪、粗灰分差异均不显著(P>0.05);在物理性状方面,pH值、色泽、滴水损失和蒸煮损失均有明显差异(P<0.05),黑色牛肉的嫩度与正常色泽牛肉的嫩度无显著差异(P>0.05);凝胶特性方面,黑色牛肉的凝胶强度和凝胶保水性要高于正常色泽牛肉,且差异显著(P<0.05)。

Abstract: Beef biceps femoris muscles were used to comparatively analyze differences in physcio-chemical properties and gel properties of DFD beef and normal colored beef. The results showed that DFD beef and normal colored beef significantly differed in their moisture content (P <0.05), but their differences in crude protein, crude fat and crude ash contents had no statistical significance (P>0.05). There was no significant difference in their tenderness (P> 0.05). Furthermore, DFD beef exhibited significantly higher gel strength and water hold capacity (WHC) as compared to normal colored beef.

Key words: DFD (dark firm dry) beef, physico-chemical properties, gel properties
