The equilibrium moisture content of all samples increased significantly with increasing aw and the samples containing glyc erol had more moisture compared to the corresponding controls at the same temperature. In addition, the samples with 40% glyc erol contained more equilibrium moisture than the 20% samples. For instance, at 25 ac the moisture level of the control, 20% glycerol and 40x glycerol samples at water activity of 0.742 were 0.33, and 0.89 (g waterlg dry matter), respectively.
