The deacidification of rice bran oil by continuous liquid–liquid extraction using aqueous ethanol as the
solvent was investigated in a perforated rotating disc column (PRDC). The influence of partial acylglycerols
and minor compounds, such as phosphorus and nutraceutical compounds, on the free fatty acid mass
transfer was observed. The experimental results show that total deacidification by solvent extraction is
feasible. The losses in neutral oil, tocols and c-oryzanol were significantly lower than those reported
in the literature for alkali or physical refining of rice bran oil. A simulation of the extraction process
was also performed, and the simulated results were in good agreement with the experimental data.
