Fitting the asymptotic model to experimental data of the dehydration process of processed corn grain at 50 °C in a moisture analyzer model HR83 Mettler-Toledo. The prepared corn grain samples with alkaline cooking of 0.8% Ca (OH)₂ at 92 ° C with and without steeping time in its cooked water at times 0, 2, 4, 6, and 8 h. The asymptotic equation is properly fitted to the experimental data, which allowed calculate the rate of hydration versus time by using its first derivative. We found that the hydration rate decreases rapidly with increasing drying time.

Keywords : Dehydration Asymptotic model; nixtamalized; Corn; Dryer halogen; Steeping time.
