Abstract:
Densities and sound speeds of aqueous solutions of Erythritol, Xylitol, Sorbitol, and Maltitol were measured at 15 °C, 25 °C, 40 °C, and 45 °C using a density and sound velocity meter (DSA 5000M). The results were used to calculate the apparent and standard molar volumes and compressions, the specific volumes and compressions, as well as the hydration numbers and their temperature dependence. The volumetric results are used to characterize the hydration of sugar alcohols and are related to sweet taste chemoreception.
