Water activity at 35 °C in ‘sugar ’ + water and ‘sugar ’ + sodium chloride + water systems

Abstract
Water activities of aqueous solutions of xylose, glucose, fructose and sucrose, and of these sugars with sodium chloride, were measured and correlated with a simple empirical equation proposed by Lin et al. (1996). Parameters for the equation were obtained and, from them, values of water activity were calculated with an average relative deviation of less than 0.14% for all the systems studied.
