Title: Diffusion of water in potato starch pastes

Abstract:

The aim of the work was to describe water transport in two-component biopolymer-water systems on the basis of water activity measurements. Research material consisted oi physically (drum dried) and differently chemically modified starches (E1404, E1412, E1414, E1422). A phenomenological model was proposed which takes into consideration water transport in the gel and surface effects associated with evaporation. It was found, that water molecules in such systems undergo diffusion in two phases. Moreover, utilization of comprehensive results of water activity measurements as well as the model proposed in this study provide detailed analysis of water transport mechanism in starch gels.
