The study of fatty acid composition in raw and dry black sesame and sesame oil by GC-MS
In this study,isooctane was used as fatty acid extraction agent,sodium methanol-methanol as methyl esterification reagent,and then Q1-SIM method was established by gas chromatography-mass spectrometry,aiming to make qualitative and quantitative analysis of fat-ty acids,so as to explore the fatty acid composition in raw and dry black sesame and sesame oil.The experimental results showed that a total of 17 fatty acids were detected in raw and dry black sesame and sesame oil,mainly including C16∶0,C18∶0,C18∶1N9C and C18∶2N6C.In addi-tion,we also found five rarely reported fatty acid components:C17∶1,C18∶1N9T,C21∶0,C20∶4N6,C20∶5N3,which contained 0.019％,0.056％,0.011％,0.013％,0.045％in raw and dry black sesame oil and 0.027％,0.112％,0.010％,0.011％,0.052％in sesame oil,re-spectively.
