Abstract:In this study，meat quality characteristics of eight different breeds and genders of Aohu，Cele Black，Dorper，Duolang，Kazakh，Han，Hotan，and Hu Sheep were analyzed to explore the correlation between mutton quality characteristics and external factors as well as internal physicochemical indicators. Physical properties，minerals，and amino acid content of 8 different types of frozen hind leg meats were determined.It was found in routine index determination of meat quality that the thickness of back fat in male sheep was significantly lower than that in female sheep，while the thickness of back fat in Dorper sheep was more prominent，at 11.33 mm.However，the fat content in the hind leg meat was relatively low，only 2.58%. The mineral content determination found that iron content in Dorper lamb was the highest，at 24.37 mg/kg. The zinc content in Cele black lamb was the highest，at 40.53 mg/kg.The magnesium content in Duolang lamb was the highest，at 412.67 mg/kg.However，there was no significant difference in calcium and copper content among the eight types of lambs mentioned above. Amino acid content determination found that amino acid content in male sheep meat was slightly higher than that in female sheep，while the amino acid content in Kazakh sheep meat was significantly higher than that in other varieties，with a prominent flavor.
