  • 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 .
  • How to extract soybean oil from ethyl acetate and hexane?
  • To obtain the maximum yield of soybean oil extraction for ethyl acetate, 1-butanol, and hexane, the Soxhlet extractions were performed, whereas around 5 grams of soya flakes were extracted with 150 mL of each solvent for 4 hours in a Soxhlet apparatus (MA491/6, Marconi, Brazil).
  • Can ethanol be used as a solvent for soybean oil extraction?
  • It was possible to use single-batch experimental assays in laboratorial-scale to evaluate key parameters for soybean oil extraction using ethanol as solvent. Such parameters may assist the design and development of continuous and countercurrent extractors adopting fixed bed columns in series as contact stages.
  • Does ethyl acetate increase the yield of soybean oil extraction?
  • According to Dagostin et al. , the increase in ethyl acetate as a co-solvent in mixtures with ethanol leads to an increase in the yield of soybean oil extraction. The isomers of butanol have been found in the literature as promising solvents for vegetable oil extraction , .
  • What is deodorization in soybean oil production?
  • Deodorization removes free fatty acids and volatile compounds from the feedstock . Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , .
