摘要
The composition of total fatty acid ethyl ester (FAEE) in yeast cells and the liquid phase separated from grape must during alcoholic fermentation at different temperatures was investigated by using the solid-phase extraction method. Thirteen FAEE from butyric to linolenic acids were detected during fermentation. Significant amounts of long-chain unsaturated FAEE, including linoleic and linolenic acids derived from grape material, had already accumulated in the yeast cells by day 3 during fermentation.
