Edible Oil And Fats Extraction Process in Sudan

Which seeds are used for oil extraction?
For oil extraction in particular, it has been applied to a wide variety of seeds such as apricot, canola, soybean, sunflower, grape, acorn and walnut seeds [ 44 ].
What equipment is used for oil extraction?
Historically, oil has been pressed out of seeds by indigenous communities for centuries, and the mechanical pressing of soybeans dates back to the 1940s [ 14 ]. There are two broad categories of equipment for oil extraction: expeller press and extruder ( Figure 2 ).
Can alternative green extraction methods be used for other seeds?
As with soybean oil extraction, the economic feasibility of alternative green extraction methods for other seeds were demonstrated to be dependent on their co-products.
Can a twin-screw extruder extract oil from sunflower seeds?
The use of a twin-screw extruder for the aqueous extraction of sunflower seeds led to 35% higher oil yield than when processed in a blender [ 66 ]. Enzymes are frequently used in all realms of food processing and their addition to aqueous oil extraction offers many advantages.
