Abstract

This work reports experimental equilibrium data for fatty systems containing rice bran oil, free fatty acids, ethanol, water, gamma-oryzanol and tocols, at 298.2 K. Model fatty systems composed by refined rice bran oil, commercial oleic acid, gamma-oryzanol, ethanol and water were used for adjusting NRTL and UNIQUAC interaction parameters between gamma-oryzanol and the other pseudocompounds. UNIQUAC interaction parameters between tocols and the other pseudocomponents were determined assuming that the tocols are present at infinite dilution in the liquid-liquid equilibrium system. Despite the complexity of the systems studied, the interaction parameters obtained were capable of correctly predicting the equilibrium for systems containing Brazilian and Thai crude rice bran oils and aqueous ethanol.
