獾子油 猪油 蛇油脂肪酸成分的分析比较

Comparison of Fatty Acid in Badger oil,Lard oil and Snake oil

目的:分析比较獾子油、猪油及蛇油中脂肪酸成分。方法:以氢氧化钾/甲醇碱催化法对样品进行甲酯化衍生化预处理,采用气相色谱-质谱联用技术(GC-MS),对獾子油、猪油及蛇油中的脂肪酸组成进行测定,用离子流色谱峰面积归一化法计算各脂肪酸成分的相对含量并进行对比分析。结果:獾子油、猪油和蛇油中游离脂肪酸成分及含量均存在差别,獾子油中共检测出11种脂肪酸,高于猪油9种和蛇油10种,且獾子油中不饱和脂肪酸含量(66.946%)也高于猪油(57.012%)和蛇油(61.142%)。结论:獾子油、猪油和蛇油脂肪酸成分存在显著差别,研究为獾子油的开发和应用提供参考。

Objective： To compare the fatty acids in badger oil, lard oil and snake oil. Methods： The sample pre- treatment was achieved through methyl esterification in the presence of KOH/MeOH. The fatty acid composition of badger oil, lard oil and snake oil was analyzed by GC-MS. The peak area normalization method was used to determine and compare the per- cent content of each component. Results： The result showed that there existed obvious difference in free fatty acids among badger oil, lard and snake oil. 11 fatty acids were detected in badger oil, more than lard oil （9 fatty acids） and snake oil （10 fatty acids）. The unsaturated fatty acid of badger oil was 66. 946%, higher than that of lard oil （57. 012% ） and snake oil （61. 142% ）. Conclusion： There is difference in fatty acids between the badger oil and lard oil, Snake oil, the study lays the foundation for exploitation and application of badger oil.
