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.
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.
What is the purpose of the optimized refining process for vegetable oil?
The purpose of the optimized refining process for each vegetable oil is to maximize the elimination of undesirable materials and minimize the degradation of desirable components (phenolics, tocopherols and phytosterols) and the loss of oils simultaneously (Chew et al., 2018; Chew and Nyam, 2019 ).
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.
