Vegetable oil refining methods


Vegetable oil refining process:
Vegetable oil refining process usually includes the following sections: degumming and deacidification, decolorization, deodorization and dewaxing. The process of removing these impurities after oil extraction section and oil press section is called edible oil refining. The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible more palatable and stable against rancidity upon storage.

Refining methods for vegetable oil refining :
There are two refining methods for the vegetable oil refining in the edible oil refinery plant. They are physical refining and chemical refining. Physical refining means removing gum in oil during process of degumming in special method and removing FFA in process of deodorizing by steam. Chemical refining, however, means removing FFA in a chemical way ( Acid-base neutralization). Gum and soap foot produced is separated by centrifuges.
Vegetable oil refining - Chemical Refining
1.The finished edible oil is consistent and stable.
2.Excellent adaptability and less requirement to oil quality.
3.Less bleaching earth is added into compared with physical refining.
Vegetable oil refining - Physical Refining
1.High oil refining rate, less oil loss.
2.No waste water discharged.
3.Especially suitable for oils of high acid value, and low gum content.
4.More FFA distilled out.
