The four different ERH/EMC models including the Henderson, Chung-Pfost, modified Halsey and Oswin equations were respectively used to investigate the fitting agreement of the measured data. Based on the comparison of the residual distributions, the coefficient of determination R2 values, the residual sum of squares SSE values, and the mean relative percentage deviation P values obtained from the regression analysis of six temperatures 20、30、35、40、50 and 60 ℃ tests, the Oswin model with two parameters and the modified Oswin model with three parameters all had the equivalent representative to the prediction of ERH/EMC values for the samples of lemon balm, and was also the best predicting models for the desorption isotherms of lemon balm.
