Abstract: The mass transfer kinetics during the osmotic dehydration of sábila (Aloe vera barbadensis Miller) were analyzed. A gel-to-solution ratio of 3:1 was used over an 80-hour process. The Azuara and Peleg mathematical models were applied to describe the kinetics of moisture loss and solid gain at a constant temperature of 25 °C and fixed concentration. Although the experimental data fit both models, the Peleg model provided a better fit. Additionally, the effective diffusion coefficients were adjusted using the Arrhenius equation as a function of temperature.
