The study of water activity in aqueous solutions of some sugars

In the work water activity was studied in aqueous solutions of some sugars: maltose, glucose, maltodextrins, fructose and sucrose. The concentration dependence for activity and activity coefficient of water was obtained. Calculated values of water activity were compared with experimental data. The results of calculation and experiment have shown a satisfactory agreement indicating the adequacy of the proposed model to the real process.
