Soybean Oil Deacidification Using Membrane Separation and Supercritical Carbon Dioxide
A model oil consisting of soybean oil triacylgycerols (TAGS) and added free fatty acids (FFA as oleic acid) was used. An evaluation of the solubility of soybean oil, oleic acid and linoleic acid in supercritical carbon dioxide provided the appropriate temperature and pressure conditions to use for the membrane separation. Data obtained from the solubility tests showed the best operational conditions in terms of temperature and pressure 45°C and 306 atm, respectively.
