The equilibrium moisture sorption of the samples at different temperatures from 5 to 40 oC (Table 3) showed that temperature increase caused significant reductions in equilibrium moisture levels for all sam- ples with and without glycerol, e.g. the equilibrium moistures for the 40% glycerol sample over supersaturated salt solution of NaNO3 at 5, 25, and 40 oc were 1.15, 0.89, and 0.79 (g waterlig dry matter) respectively.
