Which methods are used in vegetable oil extraction?
From the preceding analysis, it is observed that recent research on vegetable oil extractions has been focused more on the assisted methods (microwave and ultrasound) and supercritical fluid extraction compared to the conventional solvent and mechanical extraction methods.
Does temperature affect extraction yields of peanut oil?
Sharma et al. reported a significant effect of temperature on extraction yields of peanut oils at 40 °C which however dropped significantly when temperatures were reduced to 37 °C. The drop was associated with a possibility of enzyme thermo-inactivation.
How to optimize oil extraction from plant material?
Response surface methodology is the most commonly used method to optimize oil extraction from plant material. Box-Behnken and Doehlert are better than the Centre Composite Design but much more efficient than the traditional full factorial design.
What are the methods of oil extraction from oil seeds?
Conclusions Oil extraction methods from oil seeds include conventional methods (solvent and mechanical extraction) and nonconventional or improved techniques (supercritical fluid extraction, ultrasound, microwave, and enzyme assisted extraction.
