Xanthan gum (E415)

Xanthan gum (E415) 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

Xanthan gum is a thickener made by fermenting sugar with the bacterium Xanthomonas campestris. A small amount makes sauces and dressings thick and stable.

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.
Thickener
Thickeners are substances which increase the viscosity of a foodstuff.
