Why is crude canola oil refined?

Crude canola oil is refined in order to remove undesirable minor compounds that make this oil unusable in food products. However, refining can also cause the removal of desirable health-promoting minor components from the oil.

How to choose a canola oil extraction method?

The choice of the canola oil extraction method depends on several factors, such as oil yield, oil quality, energy consumption, capital cost, regulatory constraints, and environmental impact . There are three main methods of extracting oil from canola seeds: mechanical pressing, solvent extraction, and supercritical fluid extraction .

How is canola oil produced?

Canola oil is produced by first extracting the crude oil from canola seeds either by expeller pressing only or expeller pressing followed by solvent extraction.

What are the undesirable components of crude canola oil?

In addition to the above-mentioned desirable minor components, crude canola oil contains many undesirable minor components such as free fatty acids, phospholipids, chlorophyll, trace metals, waxes, oxidation products and pesticide residues. These are generally removed during refining.
