Abstract

The relationship between the contents of methyl trans-cinnamate and the ratio of DP/DS (diameter of pileus / diameter of stalk) in the fruit-body of Tricholoma matsutake during its development was investigated. The stages of development were divided as follows: stage A is less than 1, stage B is from 1 to less than 2, stage C is from 2 to less than 3, and stage D is more than 3 of the values of DP/DS. The contents of methyl trans-cinnamate in pileus and stalk of pine mushroom ranged from $77{\mu}g/g$ to $824{\mu}g/g$ and from $7.6{\mu}g/g$ to $22.4{\mu}g/g$, respectively during its development. In the part of pileus, there is no relevance of the methyl trans-cinnamate content of pine mushroom between the stage A and B, but there was significantly different among the stage of B, C and D. In the case of stalk, the relevance of the methyl trans-cinnamate content of pine mushroom between stage D and other stages showed a low difference. In addition, as pileus of pine mushroom developed the level of the aroma compound increased as well and showed higher correlation relationship ($r^2=0.877$) between the contents of methyl trans-cinnamate in the pileus and the ratio of DP/DS. From the results of this study, we can conclude that the aromatic component of pine mushroom can be deduced from the value of DP/DS, which indicates the stage of the development appearance.
