Popis: In order to investigate the changes in volatile compounds of Morchella esculenta during drying treatments, the volatile compounds of fresh, vaccum freezed-dried, and hot air-dried Morchella esculenta from two different parts (the pileus and stipe) were compared and analyzed by electronic nose combined with headspace gas chromatography-ion mobility spectroscopy (HS-GC-IMS) techniques. The principal component analysis (PCA) of electronic nose data showed that the drying treatment significantly changed the volatile profiles of Morchella esculenta regardless of the sampling parts. The HS-GC-IMS analysis yielded a total of 41 volatile flavor compounds, and abundant amounts of alcohols (40.02%~50.76%), esters (15.82%~25.66%), and aldehydes (18.24%~20.33%) were observed for the fresh sample. Furthermore, the drying treatments resulted in the reduction of alcohols and esters in fresh Morchella esculenta, specifically by 27.39% to 33.51% and 62.14% to 68.51% respectively, while the total contents of ketones and pyrazines increased significantly (P
