Other than significant oilseeds, ultrasound-assisted methods were also used in many other edible oil extractions, such as for the extraction of oil from maize where the conditions of 250?W power, 40?kHz frequency at 40?°C temperature for 60?min gave a maximum yield of 67?±?0.27% ( Datt & Sidhu, 2019 ).
How is edible oil produced?
Conventionally, edible oil is produced by extraction with an organic solvent alone or by screw pressing prior to solvent extraction.
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.
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.
