Thermodynamic and statistical analysis of soybean oil extraction

  • 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 .
  • 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.
  • What is soybean processing?
  • Soybean processing can be broken down into two (if screw pressing) or three (if solvent extracting) major areas: preparation (cleaning, dehulling, flaking, expanding), extraction (screw pressing, solvent extraction), and oil/meal finishing (oil and meal desolventizing, oil cooling and filtering, and meal toasting, drying, cooling and grinding).
  • How is oil extracted from soybeans?
  • Direct solvent extraction became the preferred processing method in the 1950s. In hard screw pressing, the liquid oil is squeezed or pressed from the soybean solids known as cake, usually after cooking and/or drying the beans to enhance the efficiency of continuous screw presses in removing oil ( Fig. 11.1).
