Chinese. [目的] 分析安卡鸡脂肪酸组分。[方法] 应用气相色谱- 质谱联合技术对安卡鸡脂肪酸组分进行分析, 并计算各脂肪酸的相对含量。[结果] 安卡鸡肌肉中共分离和鉴定出16 种脂肪酸, 其中饱和脂肪酸7 种, 包括月桂酸、豆蔻酸、十五烷酸、棕榈酸、十七烷酸、硬脂酸和花生酸, 其含量占总脂肪酸的38 .55% ; 不饱和脂肪酸9 种, 包括11-十四碳烯酸、9-十六碳烯酸、9-十八碳烯酸、9 ,12-十八碳二烯酸、6 ,9 ,12-十八碳三烯酸、11-二十碳烯酸、10 ,13-二十碳二烯酸、7 ,10 ,13-二十碳三烯酸以及5 ,8 ,11 ,14-二十碳四烯酸, 其含量占总脂肪酸的61 .45% 。多不饱和脂肪酸占总脂肪酸含量的23 .58 % , 必需脂肪酸占23 .04% 。[结论] 该研究为家禽肌肉中脂肪酸成分分析及营养价值的评定提供了依据。

English. [Objective] The aim was to analyze the components of fatty acids in Anak chicken. [Method] The components of fatty acids in Anak chicken were analyzed by gas chromatography - mass spectrometry technology (GC-MS) and the relative content of each fatty acid were calculated. [Result] 16 kinds of fatty acids were separated from Anak chicken muscle and identified. Among them, 7 kinds fatty acids , including lauric acid , myristic acid , pentadecanoic acid , palmitic acid , margaric acid , stearic acid and eicosanoic acid , were saturated fatty acids and its content accounted for 38 .55 % of the total fatty acids ; 9 kinds fatty acids , including 11- teteadecenoic acid , 9- hexadecenoic acid , 9-vaccenic acid , 9 ,12-octadecadienoic acid , 6 ,9 ,12-octadecatrienoic acid , 11-eicosenoic acid , 10 ,13-eicosenoic acid, 7 ,10 ,13-eicosatriennoic acid and 5 ,8 ,11 ,14-arachidonic acid , were unsaturated fatty acids , and its content accounted for 61 .45% of the total fatty acids . The polyunsaturated fatty acids accounted for 23 .58 % of the total fatty acids and the essential fatty acids accounted for 23 .04%. [Conclusion] The research provided the basis for the analysis on fatty acid components and evaluation on the nutritive value.
