Edible Oil Refining Process

Degumming and Bleaching

Crude oil contains phosphotides that need to be removed via acid degumming. To remove these gums, as well as to produce an attractive colour, oil needs to go through a bleaching process.


To achieve good quality oil, free fatty acids and odour must be removed through a deodorising process. Here, the oil is heated to a high temperature under vacuum in order to strip away the free fatty acids along with its odour.
