摘要
为探究东乡羊肉品质,选择9月龄健康东乡肉羊、小尾寒羊和湖羊公羊各10只,测定分析肉品质、脂肪酸水平、挥发性风味物质及矿物质含量等。结果显示,东乡羊肉中瘦肉精、抗生素、磺胺类药、重金属等指标均符合绿色安全标准,组织形态、色泽、黏度均符合正常鲜肉标准;东乡羊肉的色度、失水率显著高于其他两种羊(P<0.05);东乡羊肉所含蛋白质、肉类风味物质相对含量显著高于同类产品平均水平(P<0.05),多不饱和脂肪酸与脂肪酸、脂肪酸n-6与脂肪酸n-3的比值均显著高于同类产品平均水平(P<0.05);不良风味物质、胆固醇、脂肪的含量均显著低于同类产品平均水平(P<0.05);东乡羊肉铁、镁、钾含量均显著高于同类产品(P<0.05)。研究表明,东乡羊肉具有良好的营养、保健作用,能够增强人体抵抗力及免疫功能,脂肪酸含量和比例更符合人类健康膳食标准。
In order to explore the quality of mutton in Dongxiang County,ten healthy nine-month-old Dongxiang mutton sheep,small-tailed Han sheep and Hu sheep rams were selected to determine and analyze the meat quality,fatty acid levels,volatile flavor substances and mineral content,etc.The results showed that the indicators of clenbuterol,antibiotics,sulfa drugs,and heavy metals in Dongxiang mutton sheep all met the green safety standards,and the tissue shape,color and viscosity all met the requirements of normal fresh meat standards.The color and water loss rate of Dongxiang mutton sheep were significantly higher than the other two types of sheep(P<0.05).The relative content of protein and meat flavor substances in Dongxiang mutton sheep was significantly higher than the average level of similar products(P<0.05),the ratios of polyunsaturated fatty acids to fatty acids and fatty acid n-6 to fatty acid n-3 were significantly higher than the average level of similar products(P<0.05).The content of undesirable flavor substances,cholesterol and fat are significantly lower than the average level of similar products(P<0.05).The iron,magnesium and potassium content of Dongxiang mutton sheep were significantly higher than that of similar products(P<0.05).The Study indicates that Dongxiang mutton sheep has good nutrition and health effects,can enhance human resistance and immune function,and the content and ratio of fatty acids are more in line with human health dietary standards.
