title: Characteristic odorants from bailingu oyster mushroom (Pleurotus eryngii var. tuoliensis) and summer oyster mushroom (Pleurotus cystidiosus).
abstract: In this study, the characteristic odorants of the volatile oils from Pleurotus species (P. eryngii var. tuoliensis and P. cystidiosus) were extracted by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O), and aroma extract dilution analysis (AEDA). A total of 52 and 54 components (P. eryngii var. tuoliensis and P. cystidiosus, respectively) were identified, representing about 98.8% and 85.1% of the volatile oils, respectively. The main components of the P. eryngii var. tuoliensis oil were palmitic acid (82, 38.0%), oleic acid (86, 25.0%) and linoleic acid (85, 9.7%). The main components of the P. cystidiosus oil, palmitic acid (82, 25.8%), indole (54, 9.1%) and myristic acid (77, 5.3%). Regarding the aroma components, 16 and 13 components were identified in the P. eryngii var. tuoliensis and P. cystidiosus oils respectively, by the GC-O analyses. The results of the sniffing test, odor activity value (OAV) and flavor dilution (FD) factor indicate that methional, 1-octen-3-ol and nonanal are the main aroma-active components of P. eryngii var. tuoliensis oil. On the other hands, dimethyl trisulfide and 1-octen-3-ol were estimated as the main aroma-active components of the P. cystidiosus oil.
