Which industrial technologies are used for vegetable oils’ refining?
The present review aimed at comparing the two main industrial technologies used for vegetable oils¡¯ refining, namely, chemical refining and physical refining. Chemical refining removes free fatty acids by soda neutralization.
How does edible oil refining reduce production costs?
In edible oil refining, the continuous effort to reduce overall production costs is mainly achieved by increasing plant capacities, installation of mono feedstock plants, and increasing the degree of automation. Over the years, more energy-efficient processes and technologies, resulting in a higher refined oil yield, have gradually been introduced.
What is vegetable oil refining?
As vegetable oil is an important component of the human diet, the source and the processing play an important role in consumer acceptability. To remove impurities that affect the color, palatability, stability, and safety of oil, crude vegetable oil must be refined. This review highlights the processes and steps used in vegetable oil refining.
Why is refining important?
In general, refining is a necessary process to ensure the quality of edible oils. It is very important to remove unnecessary components while retaining the important components of the oils. However, the refining process may cause oxidation of the oils and produce unfavourable degradation products, which may affect the quality of the oils.
