应用“同时蒸馏-萃取”(SDE)装置提取出干香菇的挥发性风味成份。再由旋转带式蒸馏器浓缩样品。经GC/MS鉴定出91种组份。包括硫醚、硫醇和含硫成环化合物、噻唑、呋嘀和吡嗪等类杂环化合物,以及醇、醛、酮、酯等。硫化物中的3,5-二甲基-1,2,4-三硫杂环戊烷首次被发现。 The volatile flavor components of dried shiitake mushrooms were extracted by using “simultaneous distillation-extraction” (SDE) device. The sample was again concentrated by a rotary belt distiller. 91 components were identified by GC / MS. Including thioethers, mercaptans and sulfur-containing ring compounds, heterocyclic compounds such as thiazole, furosemide and pyrazine, as well as alcohols, aldehydes, ketones, esters and the like. For the first time, 3,5-dimethyl-1,2,4-trithiolane in sulfide was found.
