We used solid phase extraction and gas chromatography-flame ionization detector(SPE-GC-FID).Effects of different vintage technologies(pectases,yeasts,malolactic bacterias and fermentation temperature) on the formation of ethyl carbamate in Cabernet Gernischt wines during vinification were studied.The results showed the concentration range of ethyl carbamate in dry red wines was 7.00~26.80 μg/L,and the average was 17.90 μg/L.In dry white wines,the concentration range was 6.40~21.58 μg/L and the average was 11.35 μg/L.The ethyl carbamate is formed mainly from yeasts and malolactic bacterias during winemaking.The lower temperatures of alcoholic fermentation and the supplements of pectases before alcoholic fermentation could contribute to minimize the production of ethyl carbamate in wine.
