Green solvents and technologies for oil extraction
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

Improving Oil Extraction from Canola Seeds by Conventional
Canola seeds are one of the most important sources of edible vegetable oils globally. Crude canola oil is industrially extracted from canola seeds by expeller-pressing of heat-preconditioned flaked seeds. The residual oil in the pressed ¡ùcanola cake¡ì is recovered by solvent extraction using hexane. However, hexane extraction may pose adverse safety and environmental impacts compared to

Rapeseed
Binomial name. Brassica napus. L. [note 1] Rapeseed ( Brassica napus subsp. napus ), also known as rape and oilseed rape, is a bright-yellow flowering member of the family Brassicaceae (mustard or cabbage family), cultivated mainly for its oil-rich seed, which naturally contains appreciable amounts of erucic acid.

Understanding Hexane Extraction of Vegetable Oils
During extraction, hexane flows through a bed of flaked soybean or soybean collets (if the material has been expanded in an Anderson Solvex Expander), swiftly dissolving the oil from the solid seed material. The hexane extraction process creates two byproducts: a mixture of oil and hexane called miscella, which contains about 25-35% fat, and
