Monopotassium phosphate
Function: Emulsifier
E340I is the European food-additive number for Monopotassium phosphate, an emulsifier — helps ingredients that normally separate, like oil and water, stay mixed. Monopotassium phosphate (E340i) is an emulsifier used as a food additive.
What is E340I used for?
Monopotassium phosphate (E340I) is an emulsifier — helps ingredients that normally separate, like oil and water, stay mixed. It is added during food production for a technological purpose rather than for nutrition.
Is E340I safe or restricted?
E340I is approved for use in the EU. It sits among the additives EFSA keeps under ongoing review as new evidence is published. Forkin classifies it as “Under monitoring” and does not make health claims. See the methodology for how regulatory levels are assigned.

- What is E340I?
- E340I is the E-number for Monopotassium phosphate, an emulsifier — helps ingredients that normally separate, like oil and water, stay mixed. Monopotassium phosphate (E340i) is an emulsifier used as a food additive.
- What is E340I used for?
- Monopotassium phosphate (E340I) is an emulsifier — helps ingredients that normally separate, like oil and water, stay mixed. Manufacturers add it during processing rather than for nutrition. The Forkin app shows which products in your scan history actually contain it.
- Is E340I vegan or vegetarian?
- It depends on the source. Many additives can be produced from plant, mineral, or animal-derived raw materials, and the ingredient list rarely states which was used. The Forkin app shows the verified vegan and vegetarian status per product where it's known, instead of a blanket guess.
- Is E340I safe, and is it banned anywhere?
- E340I is approved for use in the EU. It sits among the additives EFSA keeps under ongoing review as new evidence is published. Forkin classifies it as "Under monitoring" and does not make health claims — see the methodology page for how regulatory levels are assigned, and the Forkin app for the full profile, including acceptable daily intake (ADI) and restrictions by country.
