  • 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 .
  • 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 .
  • Does ethyl acetate improve the extraction of soybean oil?
  • Dagostin et al. studied the extraction of soybean oil using ethanol as solvent and ethyl acetate as co-solvent; it was discovered an improvement in the extraction for the temperatures of 25 and 40 °C while no improvement in extraction was verified when 5 wt% and 10 wt% of ethyl acetate was added in ethanol at 55 °C.
  • 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.
  • Which solvent is used to extract crambe seed oil?
  • The pressurized liquid extraction (PLE) was assessed by Mello et al. using methyl acetate as a solvent to extract crambe seed oil. A higher extraction yield was achieved than n -hexane and ethanol in Soxhlet extraction. Still, the soybean oil extraction using the same method with ethanol was performed by Rodrigues et al. .
  • Can ethanol be used as a co-solvent for soybean oil extraction?
  • The extraction of soybean oil using ethanol mixed with biodiesel as a co-solvent was analyzed by Dagostin et al. . It was noticed that high temperatures positively affect the extraction. To use hydrated ethanol as a solvent, it was necessary to use vast amounts of biodiesel as co-solvent to reach the exact extraction yield as anhydrous.
