Title: Volatile compounds on dry red wines of‘Pinot Noir'from two producers in Wuwei
Abstract: The volatile compounds of‘Pinot Noir'dry red wine from two producers(Huangyanghe and Suwushan)in Wuwei were analyzed with dichloromethane as the extracts and gas chromatography-mass spectrometry(GC-MS).The odor activity value(OVA)was employed for evaluating the contribution of volatile compounds.The result showed that 57 aroma compounds were identified.The major compounds included 3-methyl-1-butanol,2-methyl-propanol,ethyl acetate,acetic acid,phenyl ethanol,1-propanol,2,3-butanediol,1-hexanoic acid,3-hydroxy-2-butanone.The main contributing compounds included 3-methyl-1-butanol,2-methyl-propanol,benzyl alcohol,ethyl octanoate,isoamyl acetate,ethyl acetate,isovaleric acid,2-methyl-butyric acid,hexanoic acid and octanoate.There were 53 aroma compounds identified form Huangyanghe wine,26 aroma compounds identified from Suwushan wine,the total aroma content was 593.49mg/Land 472.62mg/L respectively.It is suggested that there is a significant difference in type and content of major volatile compounds and main contributing compounds,the differences represent their own specific flavor characteristics.
