摘要: 利用顶空固相微萃取-气相色谱-质谱联用技术对新疆肥尾羊的脂肪的特性进行研究。结果表明:脂肪的碘值为59.6g I2/100g,酸值为0.095mg KOH/g,皂化值为190.9mg KOH/g;脂肪酸主要由肉豆蔻酸、棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸构成,分别占总脂肪酸总量的8.9%、23.6%、13.5%、34.9%、2.4%、1.3%;氨基酸的含量占样品总质量的0.02%,羊脂的挥发性成分主要由环丁醇、环己烷、乙酸乙酯等26种挥发性成分组成。

Abstract: The fat characterisics of tail fat tissue in fat-tailed sheep from Xinjiang were analyzed by solid-phase microextraction (SPME) coulped to gas chromatography (GC)-mass spectrmetry (MS). The iodine, acid, and saponification values were 59.6, 0.095 KOH mg/g, 190.9 KOH mg/g, respectively. The fatty acid composition consisted mainly ofmyristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid, which accounted for 8.9%, 23.6%, 13.5%, 34.9%, 2.4% and 1.3%, respectively. The amino acid content of the fat tissue was 0.02%. A total of 26 predominant volatile components were detected such as cyclobutanol, cyclohexane, ethyl acetate, and so on.
