Abstract:In this study, the total lipid was extracted by solvent extraction from breast and leg meat of Wuding chicken, Yanjin silky fowl and Daweishan miniature chicken.s. The fatty acids composition and contents were analyzed by use gas chromatography-mass spectrometry (GC-MS) after methyl esterification. Results showed that totally 20 kinds of fatty acids were identified in the breast and leg meat of Wuding chicken, Yanjin silky fowl and Daweishan miniature chickens, mainly including cis-9-oleic acid methyl ester, linoleic acid methyl ester, stearic acid methyl ester, palmitic acid methyl ester and arachidonic acid. The fatty acids contents of breast meats in Wuding chicken (28.470 mg/g) and Yanjin silky fowl (25.042 mg/g) were 28.470 and 25.042 mg/g, respectively, which were significant higher than that in Daweishan miniature chicken (16.769 mg/g). The fatty acids content of leg meat in Daweishan miniature chicken (51.10 mg/g) was significant higher than that in Wuding chicken (40.994 mg/g) (p<0.05).The same fatty acid composition in the three kinds of chickens was found with the similar saturated and unsaturated fatty acids proportion. However, the fatty acid contents in the three kinds of chickens had significant difference, and the fatty acids contents of leg meats were significant higher than those of breast meat in the three kinds chickens (p<0.05).
