ANALYSIS OF FATTY ACID COMPOSITIONS AND CONTENT OF BEEF FROM DIFFERENT GEOGRAPHICAL ORIGINS
摘要
Abstract
It is an important means of food safety management to build food traceability system.In this study the beef samples gathered from Jilin,Ningxia,Guizhou and Hebei were detected by Gas Chromatography（GC）,the differences of fatty acid composition among four beef-producing areas were analyzed,and the feasibility of beef geographical origin judged by fatty acid composition analysis were researched.The results indicated that there were significant differences of fatty acid composition in cattle muscles from different regions,the content of SFA（the content were higher than 62%） in Jilin and Hebei samples were extremely significantly higher than those in Guizhou and Ningxia;Ningxia contains the significantly higher content of C16：1 and C18：1 than other areas,content were 3.362% and 27.041% respectively;the content of a-C18：3,C20：5 and PUFA-n3 in Guizhou and Hebei samples were extremely significantly higher than those in Jilin and Ningxia,the content of PUFA-n3 in Jilin samples is only 46% of that in Guizhou.Fatty acid analysis technology is a potential method for beef geographical origin traceability.关键词
