Products containing E211
Common uses in industrial food
Sodium Benzoate (E211) is used by food manufacturers for preserving products against mould, yeast and bacterial growth, especially in soft drinks, sauces, pickles and sliced bread. It is most often listed in the ingredient panel as E211, Sodium Benzoate, 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 E211 (Sodium Benzoate) safe?
EFSA classifies the risk level of E211 as medium risk in its latest review. It is also flagged as controversial by independent toxicology reviewers, meaning the scientific consensus is contested. Always read the latest official opinion before drawing conclusions for your own diet, and consult a registered dietitian for medical questions.
What is E211 typically used for?
Food manufacturers use Sodium Benzoate primarily for preserving products against mould, yeast and bacterial growth, especially in soft drinks, sauces, pickles and sliced bread. 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 E211 on a label?
Look for the code E211 or its full name Sodium Benzoate 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.
