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.
2.2. Conventional Solvent Extraction (CSE) The conventional solvent extraction (CSE) process is amongst other factors based on the ability of the solvent to dissolve oils and to extract them from the seeds. Therefore, the solvent must be able to solubilize the oil for an efficient extraction. It is the most commonly used method usually carried
Solvent Extraction - AOCS
The second most prevalent solvent-extracted oilseed is rapeseed and/or the varieties called Canola [1]. Sunflower is also quite high in volume. A much lower volume or secondary use for soybean oil and rapeseed oil, gaining popularity in recent years, is as a feedstock for biodiesel fuels for diesel engines.
The influence of particle size and solvent flow rate on the kinetics of oil extraction from soybean (eight fractions from 0.433 to 0.122 mm) was studied using hexane, simulating commercial percolation type extractor. The reduction in particle size from 0.433 mm to 0.141 mm showed an increase in the oil yield. However, further reduction to 0.129 mm and 0.122 mm affected the yield due to bed
Soybean oil extraction with ethanol from multiple-batch assays
The apparatus used for experimental extraction assays was a stainless-steel column (height = 50 cm and diameter = 4.5 cm) equipped with a thermostatic jacket (with a heating and cooling circuit), a centrifugal pump for solvent recirculation, and a solvent boiler, the same facility used by Bessa et al. [20] for rice bran oil extraction. 500 g of grounded soybean collets were packaged inside a
Green solvents in the extraction of oil from soybean and other sources. Using a solvent in industrial-scale extraction requires plentiful supply, safety, low cost, non-flammability, oil extraction efficiency, and practicability [50]. Several companies recommend green solvents because they contribute to more sustainable processes [51].

Carbon dioxide with properties of 10–50 MPa pressures and 35–80 °C temperatures is the most frequent solvent used because it has a relatively low critical temperature (31.1 °C), is nontoxic, nonflammable, with good solvent power, low viscosity, high diffusivity, can be easily removed from the product (does not leave organic solvent residues), and is readily available at low cost [73,74,75].
- 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.
- How is soybean oil extracted in a continuous and countercurrent process?
- Extraction of soybean oil in a continuous and countercurrent process. Multistage extraction was experimentally reproduced from batch single-stage assays. The process efficiency was mainly limited by the oil solubility in the solvent. The minimum solvent mass flow and the number of ideal stages were calculated.
- 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 .
