The fitting quality parameters of BET and GAB models (Rss, SEE, and presented in Table 4, indicate that the GAB model gives the smaller RSS/SEE along with higher R2 and so better describes the experimental adsorption data of figs throughout the entire range water activity (0.11-0.84). This observation is similar to that reported by other researchers, who studied sorption isotherms of various fruits and vegetables. Kiranoudis et al. (1993) determined the equilibrium moisture content of potato, carrot. tomato, green epper. and onion within the range of water activity at three different temperatures (30, 45, and 60 oc and GAB model satisfactory for the prediction experimental data obtained. McLaughlin and Magee (1998) determined among for potatoes at temperatures of 30, 45, and 60 oc and, the models tested, the GAB model gave the best fits to Al et al. (2004) the GAB del represented the sorption of potato and starch and concluded that the equilibrium moisture con Akanbi et al. (2006) tents of tomato slices obey closely the equilibrium moisture contents of tomato slices obey closely the GAB equation.
