文昌鸡肌肉脂肪酸组分的气相色谱—质谱联合分析

应用气相色谱—质谱联合技术对文昌鸡肌肉脂肪酸组分进行分析,并以面积归一法,计算各脂肪酸的相对百分比含量。结果表明,文昌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n-十二烷酸、n-十四烷酸、十五烷酸、n-十六烷酸、十七烷酸、n-十八烷酸和二十烷酸,其含量分别为0.75%、1.23%、0.43%、23.86%、2.04%、11.18%、0.13%,占总脂肪酸的39.63%;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及5,8,11,14-二十碳四烯酸,其含量分别为0.15%、1.79%、25.84%、21.99%、0.48%、0.32%、0.45%、0.61%、8.75%,占总脂肪酸含量的60.37%。多不饱和脂肪酸占总脂肪酸含量的32.29%,而必需脂肪酸占总脂肪酸含量的31.23%。这一结果为家禽肌肉中脂肪酸成分分析及营养价值的评定提供了基础依据。

GC-MS Analysis on the Components of Fatty Acids in the Muscle of Wenchang Chicken

The components of fatty acids in Wenchang chicken were analyzed by gas chromatogrphy-mass spectrometry technology(GC-MS),and the relative content of each fatty acid were calculated.16 kinds of fatty acids were seperated from Wenchang chicken.Among them,7 kinds of fatty acids,including lauric anid,myristic acid,pentadecanoic acid,palmitic acid,margaric,stearic acid and eicosanoic,were saturated fatty acids.The content of those 7 fatty acids were 0.75%,1.23%,0.43%,23.86%,2.04%,11.18%,0.13%,accounts for 39.63%...
