The oat flake moisture sorption isotherms showed a clear dependence on temperature for the working values in this study. The GAB model is considered to be the most versatile sorption model available in the literature Al-Muhtaseb et al. The water activity in equilibrium equals the relative moisture of the air that surrounds it Zhang et al. Having a reasonably small number of parameters threethe GAB equation has been found to adequately represent the experimental data in the range of water activity of the most practical interest in foods, i.
