摘要:

对不同贮存期兼香型白酒的挥发性成分和三维荧光光谱进行测定。利用固相微萃取对挥发性成分进行提取、气相色谱-质谱法定性、内标法定量,对5 个不同贮存期酒样挥发性成分的变化进行研究。结果表明,不同贮存期酒样中的酸类物质相对含量呈上升趋势,醇类物质相对含量略有增加,酯类物质部分上升部分呈下降趋势。利用三维荧光光谱对不同贮存期酒样进行了测定,初步探讨了三维荧光在兼香型白酒酒龄方面的应用。

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
