Analysis of Flavoring Compositions in Dry Red Conquister Grape Wine of by GC/MS

The flavoring compositions in Conquister grape juice and in dry red wine were extracted by solvent extraction and analyzed by GC/MS.Their relative contents were determined by area normalization.The results showed that 68 kinds of flavoring compositions were identified in the juice and the ten flavoring compositions of high relative content were ethyl acetate,2-furancarboxaldehyde,5-(hydroxymethyl),4h-pyran-4-one,2,3-dihydro-3,5-dihydroxy-6-methyl,acetic acid,(E)-2-hexen-1-ol,1-hexanol,acetic acid,1-methylethyl ester,furfural,2-butenoic acid,ethyl ester and ethanol,and 68 kinds of flavoring compositions were identified in the wine,and the ten flavoring compositions of high con-centration were ethanol,1-butanol,3-methy,1-butanol,3-methyl-,acetate,phenylethyl alcohol,octanoic acid,ethyl ester,ethyl acetate,hexanoic acid,ethyl ester,octanoic acid,7-[2-(ethoxycarbonyl)-3a,5adimethoxycyclopentyl-1]-heptanoic acid,ethyl ester,and 1-hexanol.
