  • Title: Chemical composition and aroma evaluation of volatile oils from edible mushrooms (Pleurotus salmoneostramineus and Pleurotus sajor-caju).

    Journal: J Oleo Sci; 2014; 63(12):1323-32. PubMed ID: 25409690.
    Abstract:
    This study is focused on the volatile oils from the fruiting bodies of Pleurotus salmoneostramineus (PS) and P. sajor-caju (PSC), which was extracted by hydrodistillation (HD) and solvent-assisted flavor evaporation (SAFE) methods. The oils are analyzed by gas chromatography-mass spectrometry (GC-MS), GC-olfactometry (GC-O), and aroma extract dilution analysis (AEDA). A total of 31, 31, 45, and 15 components were identified in PS (HD and SAFE) and PSC (HD and SAFE), representing about 80.3%, 92.2%, 88.9%, and 83.0% of the oils, respectively. Regarding the aroma-active components, 13, 12, 13, and 5 components were identified in PS (HD and SAFE) and PSC (HD and SAFE), respectively, by the GC-O analyses. The results of the sniffing test, odor activity value (OAV) and flavor dilution (FD) factor indicate that 1-octen-3-ol and 3-octanone are the main aroma-active components of PS oils. On the other hands, methional and 1-octen-3-ol were estimated as the main aroma-active components of PSC oils.
