Abstract:The aromatic composition of fruit wines fermented with Enterobacter Xiangfang was analyzed by headspace solid phase micro-extraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). The results showed that the main aroma components produced by Enterobacter Xiangfang were phenylethanol, 3-methyl-1-butanol, 2-methyl-butanol and their corresponding acetates in the early fermentation stage, and heptaldehyde, 2,4,5-trimethyl-1,3-dioxolane, ethyl decanoate, ethyl octanoate, isobutyric acid and so on in the later fermentation stage. The main aroma components produced by yeast fermentation were ethyl decanoate, phenylethanol, ethyl octanoate, 2,4,5-trimethyl-1,3-dioxolane, 3-methyl-1-butanol, acetal, ethyl Dodecanoate and so on. Compared with yeast fermentation, Enterobacter Xiangfang fermentation not only had the basic aroma composition of fruit wine, but also had its unique aroma characteristics.
