Abstract

The extraction kinetics of rice bran oil (RBO), free fatty acids (FFA), and oryzanol using ethanol (0 and 6.3 mass % of water) at 40 degrees C-70 degrees C were investigated. High extraction temperatures increased the yields of RBO and oryzanol by increasing the diffusivity of the solvent, regardless of its water content. Two models that permitted the estimation of mass transfer and diffusion coefficients were fitted to the oil extraction data with low average relative deviations (5.92%). The diffusion coefficient (1.93-7.46 x 10(-10) m(2).s(-1)) increased with increasing temperature and decreasing hydration of the solvent. (AU)
