a The odor quality of compounds were taken from http://www.thegoodscentscompany.com/, accessed on May 2022; b OTs: Odor thresholds in water; c Concentration: Data are shown as the mean ± standard deviation (n = 3). Different letters in each column represent significant difference (p < 0.05); d OAVs were calculated by dividing the concentration of an odorant by its odor threshold values in water.
