Abstract:

In this work, volatile compounds and three-dimensional fluorescence spectra of fresh and stored samples of miscellaneoustype
Chinese liquor were measured. Volatile compounds were extracted by solid-phase micro-extraction, and qualitative and
quantitative analyses were carried out by GC-MS and internal standard method. The changing patterns of sixty-three compounds in
the liquor were investigated. The results showed that the relative content of acids increased, so did alcohols, and esters tended to rise or
decrease. The relationships between three-dimensional fluorescence spectra and liquor age were also investigated

Key words: solid-phase microextraction, gas chromatography-mass spectrometry, liquor, volatile compounds, threedimensional fluorescence
