摘要: 试验选用健康、体重相近,全放牧饲养条件下24月龄的云南圭山红骨山羊和非红骨山羊各8头进行屠宰试验,比较两者之间肉品质物理参数、感官品定及肌纤维特性指标,探索红骨山羊肉品质形成的规律及食用品质,旨在为云南山羊的品种改良和云南的肉羊生产提供科学的理论依据。试验结果表明,宰后45 min红骨山羊背最长肌红度值a*显著高于非红骨山羊(P<0.05),宰后24 h红骨山羊股二头肌的亮度L*值和黄度b*值显著低于非红骨山羊(P<0.05);红骨山羊背最长肌和股二头肌的剪切力显著高于非红骨山羊(P<0.05);两种山羊背最长肌的肌纤维直径和密度、熟肉率和失水率差异不显著(P>0.05);感官品定指标显示红骨山羊膻味评分显著低于非红骨山羊(P<0.05),总体口感评分显著高于非红骨山羊(P<0.05);两种山羊的嫩度、多汁性、油腻程度和结缔组织评分结果差异不显著(P>0.05)。

Abstract: Sixteen castrated male goats each of red-boned goats and normal boned goats were used to evaluate on the meat quality in the Yunnan Guishan of China. The meat from red-boned goats had significantly higher a* values of LD muscle at 45 min of post-mortem(P<0.05), while the normal boned goats had significantly higher CIE L* and b* value in rump muscle (B femoris, BF) at 24 h of post-mortem(P<0.05).The red-boned goats had significantly higher muscle shear force than that of the normal bone goats in both types of muscle (P<0.05). No significant differences between the two types of goats were measured for cooking rate, water holding capacity (WHC), muscle fibre diameter and density in both types muscle (P>0.05). The meat from red-boned goats had significantly lower (P<0.05) ordor and significantly higher overall flavour compared with the normal boned goats (P<0.05) and no significant difference was measured for juiciness, tenderness, oiliness and connective tissue score between the two types hybrid goats(P>0.05).
