Abstract:

Simultaneous distillation (SDE) and extraction method and head-space solid phase micro-extraction method (HS-SPME) were employed for sampling in GS-MS analysis of volatile components in commercial Douchi, respectively. Totally 96 compounds were identified, including 40 hydrocarbons, 13 esters and 11 aldehydes, 9 alcohols, 7 acids, 6 ketones, 7 phenols and 3 other heterocycles. There were more components extracted with SDE than those with HS-SPME, and SDE method provided better results in detecting high boiling-point and low volatile compounds, while SPME method was more rapid, simple, and nondestructive. A comprehensive evaluation on volatile components in Douchi products could be obtained by the combination of both methods.

Key words: Douchi, volatile components, SDE, HS-SPME
