摘要

Fen-Daqu is a saccharifying agent and fermentation starter for the production of Chinese liquor Fen (alcoholic spirit) and Fen traditional vinegar. The volatile compounds produced at seven incubation steps were analysed by HS-SPME-GC-MS. A total of 83 major volatile compounds were identified, including 23 esters, 8 acids, 24 alcohols, 18 ketones and aldehydes, 6 pyrazines and 4 acetals. Data obtained by HS-SPME-GC-MS were subjected to principal component analysis. The trajectory plots of volatile compounds in Fen-Daqu samples obtained during successive steps of incubation were revealed. The major compounds that contributed to discrimination were hexanal, (E)-2-octenal, (Z)-2-octen-1-ol, nonanoic acid, 1-octanol, 2-decen-1-ol, hexyl acetate, (E)-2-octen-1-ol, acetic acid, ethyl acetate, phenylethyl alcohol, ethyl alcohol, octanoic acid, 1-octanol, 3-methyl-2-buten-1-ol and pyrazines.
