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。

Abstract: 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.

Key words: muscle, frozen storage time, quality
