The general impact of glycerol on sorption isotherms observed in this research is similar to its effect in glycerol-whey protein mixtures, studied in edible films by Coupland et al. (2000) who reported that glycerol drew water into food systems while keeping its water activity low. Taken together, the equilibrium moisture content of dried figs at each aw is significantly influenced by the amount of glycerol present. The BET and GAB equations were able to fit the experimental data in figs as a high sugar system. This work confirmed that glycerol has a good potential for use as a hygroscopic ingredient in figs, in order to hold more water at a specific water activity. This could be thought of as a promising approach to modify the hard texture of dried figs with long shelf life in terms of microbial stability. More work is needed on the effect of glycerol on textural hardness, sensory characteristics and glasslrubber transition temperature of figs
