摘要

Baijiu - Chinese white spirits - contain a plethora of volatile compounds of which only some have been identified. This study reports two pre-treatments, direct injection and headspace solid phase microextraction (HS-SPME), coupled with gas chromatography mass spectrometry to analyse the volatile compounds of liquor distilled from grains fermented in 100-, 200- and 300 year-old cellars. Three samples from each cellar were analysed and 71 compounds were detected using direct injection with 75 compounds detected using HS-SPME. The compounds included esters, alcohols, carboxylic acids, aldehydes and ketones and other compounds. Although both methods detected a similar number of compounds, the types of compounds detected differed. The collection times of the samples were divided into four stages according to their composition. This study provides an analytical foundation for further determining components in baijiu.
