heal.abstract	In this work, the hydration mechanism of soluble starch has been investigated by means of equilibrium water sorption and desorption isotherms, and of thermally stimulated depolarization currents (TSDC) techniques in the temperature range 77-300 K. The water content, h, of the samples was varied between 0 and 0.39 g of water/g of dry sample. The results of equilibrium water sorption measurements were analyzed by means of the Guggenheim-Anderson-De Boer (GAB) equation in terms of bound and clustered water. Two TSDC peaks were observed and the dependence of their characteristics on water content was studied.	en
