摘  要：
研究新疆巴什拜羊不同部位肌肉,在-18℃冻藏0.5、1、2、7、15、30d后肉品质的变化。结果表明:在冻藏期间,肩肌、臀肌、背最长肌粗脂肪、总胶原蛋白含量及剪切力值差异显著(P<0.05),而胶原蛋白溶解度无显著差异(P>0.05)。冻藏时间对肩肌的解冻和蒸煮损失有极显著影响(P<0.01),而对臀肌和背最长肌无显著影响(P>0.05);对肩肌和臀肌的结缔组织滤渣有极显著影响(P<0.01),而对背最长肌无显著影响(P>0.05)。随着冻藏时间的延长,3个不同部位肌肉剪切力逐渐下降(P<0.05)。背最长肌的水分含量、剪切力较低,粗脂肪含量较高,具有较好的嫩度。臀肌的剪切力最高,嫩度最差。

摘  要：
Quality changes in mutton from different parts of Bashbay sheep carcass after storage at-18 ℃ for 0.5,1,2,7,15 d and 30 days were investigated.Significant differences in crude fat and total collagen contents and shear force existed among shoulder,gluteus and longissimus dorsi muscles during frozen storage(P<0.05),whereas no significant differences in collagen solubility were observed(P>0.05).Frozen storage time had extremely significant effects on the thaw drip and cooking loss of shoulder muscle and the filtration residue content of connective tissue in shoulder and gluteus muscles(P<0.01),but did not has significant effects on longissimus dorsi(P>0.05).A gradual decrease in shear force was observed for three muscles with prolonged storage time(P<0.05).longissimus dorsi revealed lower levels of moisture and shear force but a higher level of crude fat and better tenderness than shoulder and gluteus muscles,whereas gluteus muscle had the highest shear force and the worst tenderness.
