The most commonly used extraction process to produce high oil yield from canola seeds involves both mechanical pressing and solvent extraction as shown in Fig. 1. Daun has detailed the conventional extraction of canola oil. A series of steps occur prior to and in preparation for expeller pressing.
How is crude canola oil extracted?
Crude canola oil is industrially extracted from canola seeds by expeller-pressing of heat-preconditioned flaked seeds. The residual oil in the pressed B canola cake^is recovered by solvent extraction using hexane. However, hexane extraction may pose adverse safety
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 .
