Title: Determination of volatile aroma compounds in litchi vinegar by HS-SPME-GC/MS
Abstract: The volatile compounds of Litchi vinegar were extracted by solid phase micro extraction and were identified by the analysis of gas chromatography-mass spectrometry.About 34 different components were identified including acids,alcohols,aldehydes,ketones,esters,hydrocarbons and a few other compounds.The percentage of each component was determined by area normalization.It was indicated that the main volatile components in the Litchi vinegar were acetic acid(61.6%),ethyl acetate(7.91%),3-hydroxy-2-butanone(6.44%),isoamyl acetate(2.97%),phenethyl acetate(2.87%),diisobutyl phthalate(2.25%),(2R,3R)-(-)-2,3-butanediol(2.09%),isobutyl acetate(1.74%),2,3-butanediol(1.61%),octanoic acid ethyl ester(1.42%),acetic acid 2-methylbutyl ester(1.37%),ethyl alcohol(1.25%).
