Diffusivity of starchy endosperm and bran of fresh and re wetted rice

, : Diffusivity of starchy endosperm and bran of fresh and re wetted rice. Journal of Food Science 45(2): 356-361

Mathematical equations based on Fick's law of diffusion were used to model the thin-layer drying of rewetted white and brown rice. Diffusivities of the starchy endosperm and bran were determined by minimizing the sum of squared deviations between the theoretically predicted and observed drying curves. Diffusion coefficients calculated for the rewetted materials were compared to those reported for fresh materials and were statistically equivalent. Volumetric data for white and brown rice were collected for use in specifying the mathematical models.
