E471 - Mono- and diglycerides

Origin:
Synthetic fats, produced from glycerol and natural fatty acids, mainly from plant origin, but also fats of animal origin may be used. The product generally is a mixture of different products, with a composition similar to partially digested natural fat.
Function & characteristics:
Emulsifiers and stabilisers.
Products:
Many different products.
Acceptable Daily Intake:
None determined.
Side effects:
None known. The body metabolises the products as any other fat. The individual components are also produced normally in the body when digesting normal fat.
Dietary restrictions:
Although mainly vegetable oils are used, the use of animal fat (incl. pork) can not be excluded. Several groups, such as vegans, Muslims and Jews thus avoid these products. Only the producer can give detailed information on the origin of the fatty acids. Chemically the fatty acids from vegetable or animal origin are identical.
