Common uses in industrial food

Carrageenan (E407) is used by food manufacturers for increasing viscosity in dairy desserts, sauces, soups and plant-based drinks. It is most often listed in the ingredient panel as E407, Carrageenan, or under one of its trade names. On a NutriDécrypte product page, this additive contributes to the additives axis (20% of the overall A to E grade), and triggers a label warning when its EFSA risk level is medium or high.

If you want to limit your exposure to this additive, the simplest tactic is to read the ingredients list (not just the front-of-pack), and to favour products graded A or B in our independent catalog. Less processed, NOVA-1 or NOVA-2 categories rarely contain it.

Frequently asked questions

Is E407 (Carrageenan) safe?

EFSA classifies the risk level of E407 as medium risk in its latest review. It is also flagged as controversial by independent toxicology reviewers, meaning the scientific consensus is contested. Several jurisdictions have restricted or banned its use, including: Infant formula US. Always read the latest official opinion before drawing conclusions for your own diet, and consult a registered dietitian for medical questions.

What is E407 typically used for?

Food manufacturers use Carrageenan primarily for increasing viscosity in dairy desserts, sauces, soups and plant-based drinks. You will most often find it in ultra-processed foods (NOVA group 4) and rarely in unprocessed or minimally processed products (NOVA 1 or 2).

How can I avoid E407 on a label?

Look for the code E407 or its full name Carrageenan in the ingredients list, usually printed in small font on the back of the pack. Cooking from raw ingredients, choosing NOVA-1 or NOVA-2 alternatives, and using the NutriDécrypte rankings to filter by grade A or B are the three most reliable strategies.
