• 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 ethanol and isopropanol be used for soybean oil extraction?
  • Gandhi et al. noticed a loss of approximately 5¨C7% when using ethanol and isopropanol for soybean oil extraction at a laboratory scale. However, Silva et al. claimed that the reuse of ethanol leads to water accumulation in the solvent, which might reduce the extraction yield.
  • What solvent is used to make soybean protein concentrate?
  • It should be noted that other solvents may be required to produce different and specific products; for example, an alcohol-water mixture is used in an additional extraction step (after hexane extraction) to produce soy protein concentrate (or ¡°SPC¡±) by removing the sugars from standard soybean meal (Wang et al., 2004).
  • How hexane is used to extract soybean oil?
  • However, efforts have been made to reduce the costs (Reverchon and Osseo 1994). Solvent extraction of soybeans is a diffusion process in which the solvent (hexane) selectively dissolves miscible oil components. During extraction, hexane solubi lizes soy oil from cotyledon lipid bodies in soy flakes rapidly, as soon as it enters the lipid body.
  • 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 modern soybean oil?
  • Modern soy oil is a stable high quality triglyceride ingredient used widely in commercial processed foods. It is without other lipid contaminants and available at a reasonable cost. Modern soybean processing starts with solvent extraction to obtain crude oil and defatted meal.
