  • How to extract soybean oil?
  • Soybean oil can be obtained by expelling or using an organic solvent. Although, the employment of solvent will always follow the expelling to increase lipid extraction yield .
  • Which solvent is used in soybean oil production?
  • Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , . This solvent has a high solubility for oil extraction, availability, low price, low boiling point, and heat of vaporization .
  • Is ethanol better than hexane for soybean oil extraction?
  • Despite the fact that soybean oil extraction with hexane is more efficient, in terms of a more concentrated miscella, the outcomes obtained in this study revealed that is possible to exhaust the raw material with ethanol, and that a high oil recovery value can be reached when a S / F = 3/1 is employed.
  • Can soybean oil be extracted with ethanol?
  • Still, the soybean oil extraction using the same method with ethanol was performed by Rodrigues et al. . The results were almost similar to those obtained in Soxhlet extraction. The PLE using isopropanol and ethanol as a solvent for extracting nut kernel oil was performed by Cornelio-Santiago et al. .
  • Can green solvents be used in soybean oil extraction?
  • The application of green solvents in soybean oil extraction is reviewed. Hansen parameters and COSMO-based models can serve as a solvent selection tool. Direct substitution of hexane with green solvents is the most promising alternative. Kinetic models and the thermodynamic assessment are analyzed comprehensively.
  • Can hexane be used for soybean oil extraction?
  • In contrast, some advanced technologies such as enzyme-assisted, supercritical fluids, deep eutectic solvent, and ionic liquids seem less efficient than ordinary processes using hexane for soybean oil extraction. The best alternatives for replacing hexane seem to be ethanol, ethyl acetate, the terpenes, 2-MeTHF, and CPME.
