Green solvents and technologies for oil extraction from oilseeds
The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solvent has lead to several
The extraction of soy oil from soybean flakes in industry requires large amounts of hexane solvent and results in significant losses and energy consumption during the distillative removal of the solvent. Hexanes and related hydrocarbon extractants are also becoming an environmental and health concern. A new
Recent advances in green soybean oil extraction: A review
The current technologies and green solvents used for soybean and general vegetable oil extraction are presented. Besides, main kinetic and thermodynamic approaches are reviewed, and tools for screening solvents are presented. Issues regarding cost, recovery, and reuse of green solvent are assessed.
Abstract. Soybeans are the dominant oilseed in both U.S. and world markets. During a typical year soybean production comprises over half the worldwide oilseed production ( Anonymous 1995 ). However, according to Dutton (1981) in the early 1940s, soybean oil was considered a poor quality oil, not suitable for food use, and more appropriate for
Soybean oil extraction and separation using switchable or expanded
Supercritical CO 2 (scCO 2) could be used but requires 500 bar for the most energy-efficient extraction of soy oil from soybeans (i.e. minimum energy cost per kg of extracted oil). 2,3 Soybean oil is miscible with many other low polarity organic solvents, especially those having a Hildebrand solubility parameter less than or equal to 22 MPa 1 /2 .
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.

Extrusion has been used as pretreatment prior to expeller pressing of soybean oil, extracting over 70% of oil compared to single-step expelling, which yielded 60% . This process has also been used for simultaneous treatment with fatty acid methyl ester as a solvent, extracting 98% of oil from sunflower seeds .
The thermodynamic assessment showed endothermic, and spontaneous processes for both solvents. 1-Butanol, ethyl acetate, and hexane have a better performance on the yield of soybean oil extraction than using ethanol; however, ethyl acetate is the best candidate to replace the industrial use of hexane due to its highest rate of soybean oil extraction at the process beginning.
- 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 n hexane is used in oil extraction?
- The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents.
- 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.
