本研究采用气相色谱/质谱联用技术（GC/MS）测定了驼奶、羊奶和牛奶中的游离脂肪酸（FFA）含量。牛奶样品在加入乙醇和2.5 M h2so4后，用乙醚/正庚烷混合物（1:1 v/v）提取。用氨基丙基柱分离游离脂肪酸。驼奶的总游离脂肪酸含量为13.64 μmol/10 ml，羊奶和牛奶的总游离脂肪酸含量分别为13.53 μmol/10 ml和22.56 μmol/10 ml。发现骆驼和山羊乳脂中含有c4 - c20的游离脂肪酸，而奶牛乳脂中不含c18: 2和c18: 3的游离脂肪酸。结果表明，骆驼奶中游离脂肪酸（c14）含量分别是羊奶和牛奶的2.8倍和1.9倍。
In this study, free fatty acids (FFA) contents of camel, goat and cow milk were determined by using Gas Chromatography/Mass Spectrometry (GC/MS). Milk samples were extracted by diethyl ether/n-heptane mixture (1:1 v/v) after addition of ethanol and 2.5 M H 2 SO 4 . The FFA isolation was carried out with an aminopropyl column. The total FFA concentration of camel milk was 13.64 μmol/10 ml milk and goat and cow milk contained 13.53 and 22.56 μmol/10 ml milk FFA, respectively. It was found that camel and goat milk fat had FFA with C 4 -C 2 0 , while cow milk fat contained no FFA with C 1 8 : 2 and C 1 8 : 3 . It was established that FFA contents ( C 1 4 ) concentration in camel milk was approximately 2.8-fold and 1.9-fold higher than that of goat and cow milk, respectively.
