All You Need to Know About Degumming of Soy Lecithin
The water degumming process is one of the oldest ways to refine crude oil. A calculated amount of water, at around 70 degrees hot, is added to hydrate phosphatides. The hydrated phosphatides become denser and oil-insoluble creating a sludge. The created sludge is separated through a centrifugal process. Controlling the temperature and quantity of water in the degumming …
