^a Aroma description from panelists. ^b Aroma intensity from panelists. ^c FD factor from panelists. ^d Odor thresholds in water. ^e The aroma description is derived from the literature corresponding to the threshold of the compound, and the aroma description of the compound whose threshold is not found is from the website (http://www.thegoodscentscompany.com/). ^f NF means the threshold values have not been found in references. ^g The content of the hotrienol was determined by internal standard method temporarily, and its OAV value might not be accurate, so the compound was removed during aroma reconstruction and aroma omission.
