Oilseeds are crucial for the nutritional security of the global population. 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 ...
Background One of the most basic needs of mankind is an abundant and reliable food supply. In the modern world, one major source of protein and vegetable oil is from oilseeds, particularly the soybean – an abundant resource which is largely processed using solvent extraction, an efficient and reliable means to separate the high-protein meal solids from the high-energy edible oil.

Advantages of mechanical extraction include the production of good quality oil and the possibility of the use of its cake compared to when extraction is done in solvents. Oil extraction by mechanical presses is the most common and entails the use of either hydraulic presses or screw presses driven by a motor [2,21].
Extracting solvents should be completely immiscible with the original solvent. The solute to be extracted must have greater solubility in the extracting solvents; In order to remove the solute by heating the solution in a water bath, the extracting solvents must be more volatile than the solute.

The use of solvents led to differences in the shade of the oils, possibly due to the extraction of chlorophyll and carotenoids, which are common pigments in vegetable oils. Solvent extraction could facilitate the selective leaching of some types of pigments, unlike oil expression by pressing, in which the pigments would be expelled from the ...
The solvent extraction method recovers almost all the oils and leaves behind only 0.5% to 0.7% residual oil in the raw material, such as peanuts solvent extraction plant or ground nuts solvent extraction plant etc. In the case of mechanical pressing the residual oil left in the oil cake may be anywhere from 6% to 14%.

As with soybean oil extraction, the economic feasibility of alternative green extraction methods for other seeds were demonstrated to be dependent on their co-products. The values of the co-products (rapeseed meal and molasses) compensated for the higher crushing costs resulting from ethanol extraction compared to the hexane extraction of rapeseed oil [ 37 ].
The solvent extraction of vegetable oils like soybean oil dominates the oilseed industry as the most popular extraction method used around the world. Most large-scale solvent plants use hexane extraction to chemically separate oilseeds into liquid fat and solid protein—popular ingredients in the food industry and many other market sectors.

Peanuts, being crucial crops of global importance, have gained widespread recognition for their versatility and nutritional value. In addition to direct consumption, either with or without treatment, peanuts can be the subject of diverse applications focusing mainly on two distinct objectives: oil extraction and defatting processes.
