This work has as aim to study the behavior of the isotherms of the soybean meal. Therefore, experiments had been carried out by using the static method with saturated salt solution at 50, 60 and 70ºC. The data had been adjusted to the equations of the literature, using Statistica software 6.0®. The results indicated that the temperature does not affect significantly the moisture equilibrium values of the soybean meal in the range of temperatures studied and that the LUIKOV and the HALSEY models can be used to foresee the moisture equilibrium of the soybean meal.
