ABSTRACT

Density and sound velocity for solutions of carbohydrates glucose, fructose and sucrose in water and in aqueous solutions of 10% w/w of polymers PPG400, PEG400, PEG4000, and PEG10000 were measured at T = (288.15, 293.15, 298.15, 303.15, and 308.15) K. From the measured experimental data, the isentropic compressibility values of the investigated solutions were determined and from which the values of the hydration numbers of the carbohydrates were calculated. Apparent molar volume and apparent molar isentropic compressibility of the carbohydrates in the investigated solutions were also determined and based of them the sweet properties of the carbohydrates were discussed. Finally, the infinite dilutions apparent molar properties for transfer of the carbohydrates from water to aqueous solutions of different polymers were studied and the results were discussed based on the different interactions exist in the solutions.
