| 摘 要： | 为提高羊尾巴的利用价值，运用真空抽提法从苏尼特羊羊尾巴中提取羊尾油，并对其进行理化性质的测定。另外，将羊尾油进行干法分提，分为固脂、液油两部分，采用气相色谱-质谱法对原油、固脂与液油脂肪酸组成进行分析。结果表明：苏尼特羊尾油的水分及挥发物含量为8.63%,酸值(KOH)为0.67 mg/g,皂化值(KOH)为180.1 mg/g,碘值(I)为45.48 g/100 g; 3种油样都检测出16种脂肪酸，主要含有棕榈酸、油酸和硬脂酸，液油的不饱和脂肪酸含量较原油和固脂的高。

| Abstract: | In order to improve the utilization value of sheep tail, the oil was extracted from Sunite sheep tail by vacuum extraction method, and its physicochemical properties were determined. The sheep tail oil was separated into solid fat and liquid oil by dry fractionation, and the fatty acid compositions of the crude oil, solid fat and liquid oil were analyzed by gas chromatography-mass spectrometry. The results showed that the moisture and volatile matter content of Sunite sheep tail oil was 8.63%, acid value was 0.67 mgKOH/g, saponification value was 180.1 mgKOH/g, and iodine value was 45.48 gI/100 g. A tatal of 16 fatty acids were detected in the three kinds of oils, and the main fatty acid was palmitic acid, oleic acid and stearic acid. The content of unsaturated fatty acids in liquid oil was higher than that in the crude oil and solid fat. |
