Phospholipids
Another important fat emulsifier group is the phospholipids. The most common phospholipid is lecithin. Because of their carbohydrate-fat structure, they move well in fats and in water. This allows them to move easily in and out of cells. Lecithin is used, for instance, in cod liver oil supplement production as an emulsifier which allows for easier digestion of the cod liver oil. Lecithin is consumed as a dietary supplement, as it assists the breakdown of fats by the liver and gall bladder.
