Abstract

In this study, a moisture diffusion model of two-component food rice made wafer under a non-permeable packaging condition was established on the basis of water adsorption kinetics experiment and water diffusion coefficient theory under the condition of 23 ℃; The relation between water content and time change of water diffusion among components was calculated based on the Fick’s law, initial conditions, boundary conditions and moisture sorption isotherm, and then the model-calculated of moisture diffusion were tested and analyzed by experiment when the moisture content was between 0.02 and 0.12. The results showed that the experimental data could be tted with the theoretical model very well.
