Bleaching Bleaching was introduced in edible oil refining at the end of the 19th century to improve the colour of cottonseed oil. Originally, it was a batch process at atmospheric pressure, in which natural bleaching clay was added to hot oil wi

Physical refining became a reality in the 1950s for processing palm oil, which typically contains high FFA and low gum contents. The palm oil process subjected the crude feedstock first to pretreatment and then to acidification.
