Abstract

Static headspace( SHS) and solid phase microextraction( SPME) technology were used to extract odor components in infant nutrition package.Their odor components were analyzed qualitatively and quantitatively by the gas chromatography / mass spectrometry( GC- MS) and then compared the results. The results showed that the most obvious changes in the samples were aldehydes after the accelerated oxidation test.The main components of the nutritional package's rancid flavor may be Hexanal,2- pentyl furan,( E,E)-2,4- nonadienal,( Z)-14- methyl-8- hexadecene-1- acetal.Rancid flavor may be generated by the interaction of several substances.
