As is the case for coffee and wine, mushroom aroma is utilized as a means of discerning the food
value of mushrooms, so it has been analyzed using gas chromatography/mass spectrometry (GC/MS)
systems (Table 1) [12–16]. Furthermore, characteristic aroma has also been used as a marker of
mushroom discrimination [17,18]. The main components of mushroom aromas include a variety of
alcohols, and in particular 1-octen-3-ol (mushroom alcohol or matsutake alcohol) is commonly
detected in many varieties of mushrooms. However, the components of fresh mushrooms vary per their
place of origin and can change depending on the period of time after collection and storage
temperature. In a study about matsutake mushroom, the amount of the total aroma differed with the
production area [19]. Additionally, the aroma was reduced by one half when stored at 27 C for 66 h.
Another study has reported that truffles, when stored for seven days, showed less change in aroma at
+8 °C, comparing with +4 °C [20]
