Understanding Hexane Extraction of Vegetable Oils
The hexane extraction process After soybeans or other oilseeds are cleaned, cracked, cooked, and dried, the flaked seed material is bathed in hexane at a solvent plant. Proper pretreatment helps rupture the oil-bearing cells and increase the surface area of the seed, allowing the solvent to thoroughly penetrate the material to extract more fat.

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 ...

Chaabani et al. (2019) classified the lipid classes of Pistacia lentiscus oil obtained by hexane and some bio-based solvents. According to these authors, the extracts obtained with 2-methyltetrahydrofuran, ethyl acetate, dimethyl carbonate, p-cymene, and hexane have more triacylglycerols.In contrast, the extracts of isopropanol and ethanol are richer in phospholipids since alcohols have a good ...
