title: Chemical Composition and Character Impact Odorants in Volatile Oils from Edible Mushrooms.
abstract: The aim of this study was to investigate the chemical composition and the odor-active components of volatile oils from three edible mushrooms, Pleurotus ostreatus, Pleurotus eryngii, and Pleurotus abalonus, which are well-known edible mushrooms. The volatile components in these oils were extracted by hydrodistillation and identified by GC/MS, GC-olfactometry (GC-O), and aroma extract dilution analysis (AEDA). The oils contained 40, 20, and 53 components, representing 83.4, 86.0, and 90.8% of the total oils in P. ostreatus, P. eryngii, and P. abalonus, respectively. Odor evaluation of the volatile oils from the three edible mushrooms was also carried out using GC-O, AEDA, and odor activity values, by which 13, eight, and ten aroma-active components were identified in P. ostreatus, P. eryngii, and P. abalonus, respectively. The most aroma-active compounds were C8 -aliphatic compounds (oct-1-en-3-ol, octan-3-one, and octanal) and/or C9 -aliphatic aldehydes (nonanal and (2E)-non-2-enal).
