Abstract
This work aims to provide better knowledge of pyrazine and thiazole st ructural properties, exploitable in aroma extraction. An optimized ext raction method including steam-vacuum distillation and liquid/liquid e xtractions of the aqueous distillate followed by gas chromatography-ni trogen-phosphorus detector analysis enabled us to quantify 50 ppt of s uch heterocycles in a food matrix such as beer. Lipophilicity appears as a determining parameter for vacuum distillation while basicity gove rns the liquid/liquid extractions.
