Mono- and diglycerides of fatty acids (E471)

Mono- and diglycerides of fatty acids (E471) is one of the markers Open Food Facts uses to classify a food as ultra-processed (NOVA group 4).

What it is and why it counts

Mono- and diglycerides of fatty acids are made from fats and glycerol. They are among the most widely used emulsifiers in bread, cakes, ice cream and spreads.

Cosmetic additives

NOVA calls these additives "cosmetic": they change how a product looks, feels or tastes rather than keeping it safe to eat. Their presence is one of the two defining signs of an ultra-processed food.

Function

Emulsifier: Emulsifiers are substances which make it possible to form or maintain a homogenous mixture of two or more immiscible phases such as oil and water in a foodstuff.
Stabiliser: Stabilisers are substances which make it possible to maintain the physico-chemical state of a foodstuff; stabilisers include substances which enable the maintenance of a homogenous dispersion of two or more immiscible substances in a foodstuff, substances which stabilise, retain or intensify an existing colour of a foodstuff and substances which increase the binding capacity of the food, including the formation of cross-links between proteins enabling the binding of food pieces into re-constituted food.
