摘要
对青海欧拉羊肌肉脂肪酸进行分析,并与高原型藏羊和小尾寒羊的肌肉脂肪酸组成进行比较。欧拉羊肌肉提取脂肪后进行甲酯化,用气相色谱-质谱联用法测定脂肪酸组成。结果显示:在欧拉羊肌肉中分离鉴定出17种脂肪酸,其主要成分是棕榈酸(22.33%)、硬脂酸(25.91%)、油酸(39.32%)、亚油酸(1.87%),其中饱和脂肪酸占51.62%、单不饱和脂肪酸占42.41%、多不饱和脂肪酸占5.34%。欧拉羊不饱和脂肪酸含量与高原型藏羊比较,无明显差别,比小尾寒羊的含量要高。
The fatty acid composition of longissimus dorsi in Oula sheep living in Qinghai province was analyzed by GC-MS after methyl esterification and compared with that of Tibetan sheep and Small Tail Han sheep.A total of 17 fatty acids were identified in the muscle of Oula sheep,mainly consisting of stearic acid（22.33%）,palmitate acid（25 91%）,oleic acid（39.32%） and linoenic acid（1.87%）.Saturated,monounsaturated and polyunsaturated fatty acids accounted for 51.62%,42.41% and 5.34% of the total fatty acids,respectively.Oula sheep showed no remarkable differences in unsaturated fatty acid content when compared with Tibetan sheep,but was higher than mall-tail Han sheep.
