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.
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 .
Soybean oil extraction with ethanol from multiple-batch
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
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
Thermodynamic and statistical analysis of soybean oil
The results indicate that oil extraction process with ethanol is feasible and spontaneous, mainly under higher temperature. Also, the influence of water level in the solvent and temperature were analysed using the response surface methodology (RSM). It can be noted that the extraction yield was highly affected by both independent variables.
This alternative deacidification process by liquid–liquid extraction uses ethanol, a generally recognized as safe (GRAS) solvent, which allows minimizing the losses of nutraceutical compounds present in the oil. In fact, this study provides data that can be used to design a renewable solvent‐based soybean oil deacidification process.
Soybean oil extraction and separation using switchable or
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
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].
Overview of the soybean process in the crushing industry
Abstract. A minimal residual oil content in the meal coming out of the hexane extractor is a clear benefit for a crushing plant; the more oil yield the better revenue for the crusher. In a modern and efficient extraction plant, a residual oil content ≤ 0.5% for soybean meal is expected.
The results compared well with traditional solvent extraction, especially when accounting for the extremely short extraction times (min vs. h). Maximum oil yields of 17.3% and 17.2% at 20 min and 120C were achieved by microwave extraction as compared to 11.3% and 12.4% using control extraction for soybeans and rice bran, respectively.
