Each value is expressed as mean ± standard deviation (n = 3); “^a–n” means with different letters in the same column have significant difference (p < 0.05). “ND” means not detected. L, F, HA, SC, and HH represent the lemon peel samples, fresh, hot-air drying, steam-drying cycle, and high temperature and humidity, respectively. FJ, CT, and XC were commercial Chenpi samples.
