E451
E451 , Triphosphates
Why this classification
Phosphate additive, same concerns as E450.
Common uses in industrial food
Triphosphates (E451) is used by food manufacturers for binding water and oil together to keep texture stable in margarine, ice cream, mayonnaise, ready meals and ultra-processed pastries. It is most often listed in the ingredient panel as E451, Triphosphates, 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 E451 (Triphosphates) safe?
EFSA classifies the risk level of E451 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 E451 typically used for?
Food manufacturers use Triphosphates primarily for binding water and oil together to keep texture stable in margarine, ice cream, mayonnaise, ready meals and ultra-processed pastries. 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 E451 on a label?
Look for the code E451 or its full name Triphosphates 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.
