Emulsifier

Emulsifier 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

Emulsifiers keep fat and water from separating, giving products a smooth, stable texture over a long shelf life. Common examples are lecithins (E322) and mono- and diglycerides of fatty acids (E471).

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.
