Recent advances in green soybean oil extraction: A review
The extraction of soybean oil and free fatty acids was evaluated using ethanol with different hydration levels (from anhydrous to 5.98 wt%) by Toda et al. [29]. It was found that the increase in water content suppresses soybean oil extraction and increases the free fatty acids content.
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 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.
Aqueous extraction processing (AEP) of soy is a promising green alternative to hexane extraction processing. To improve AEP oil yields, experiments were conducted to probe the mechanisms of oil release. Microscopy of extruded soy before and after extraction with and without protease indicated that unextracted oil is sequestered in an insoluble matrix of denatured protein and is released by
Alternative Techniques for Defatting Soy: A Practical Review
Hexane extraction is the most common technique used to remove oil from full fat soy materials in the production of both soy oil and defatted soy. The popularity of hexane is based on its high oil extraction efficiency and its availability. The solvent, however, has some considerable economic, environmental, and safety drawbacks. A review of alternative soybean defatting techniques is carried
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
Advances in Aqueous Extraction Processing of Soybeans
The Journal of the American Oil Chemists' Society publishes original research and technological advances on fats, oils, oilseed proteins, and related materials. Abstract Aqueous extraction processing technologies, having advanced in recent years, may be a viable alternative to hexane extraction to separate oil and protein from soybeans.
In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
- Why is the soybean price a critical factor for hexane extraction?
- Material cost takes up about 44% of total operating costs in a facility producing 4 million kg of soybean oil and increases to over 90% of total operating costs in 173.22 and 415.73 million kg of soybean oil production facilities. Therefore, the soybean price is concluded as a critical factor for the hexane extraction process. 3.2.2. Utility costs
- 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 hexane be used for soybean oil extraction?
- In contrast, some advanced technologies such as enzyme-assisted, supercritical fluids, deep eutectic solvent, and ionic liquids seem less efficient than ordinary processes using hexane for soybean oil extraction. The best alternatives for replacing hexane seem to be ethanol, ethyl acetate, the terpenes, 2-MeTHF, and CPME.
- 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.
