Here are some methods for extracting food processing oils:

Mechanical extraction
The first method used in edible oil processing plants, this method uses an expeller press to extract oil from seeds.
Chemical extraction
This method uses hexane extraction.
Solvent extraction
This method involves soaking the plant or fat being extracted in a solvent, and then using heat and the solvent to separate and pull oil from the organic material.
Aqueous extraction
This method is an alternative to hexane-based oilseed extraction, and it can simultaneously recover vegetable oils and high-quality protein products.
Dewaxing
This method, also called winterization, is often used in vegetable oil refineries that process corn and sunflowers. It improves the oil's clarity and brightness by removing solids like waxes or saturated glycerides.
Desolventizing
This method is used to remove residual hexane from solid meals that result from the extraction stage of crushed oilseeds.
Supercritical fluid extraction
This method is a common way to extract lipids from foods, and has been used in the dairy industry to isolate PLs.
Green solvents
These solvents could be used as an alternative to petroleum-based solvents for extraction purposes in the food industry.
