Trisodium phosphate
Function: Emulsifiers
E339III is the European food-additive number for Trisodium phosphate, an emulsifier — helps ingredients that normally separate, like oil and water, stay mixed. TRISODIUM PHOSPHATE is the inorganic compound with the chemical formula Na3PO4.
What is E339III used for?
Trisodium phosphate (E339III) 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. See all Emulsifiers (E-numbers).
Is E339III safe or restricted?
E339III faces restrictions under EU rules on how, where, or in what quantities it may be used. Forkin classifies it as “Restricted use” and does not make health claims. See the methodology for how regulatory levels are assigned, or the guide to how EU additives are approved, re-evaluated and banned.
Is E339III vegan or vegetarian?
Trisodium phosphate (E339III) is typically produced from plant, mineral, or synthetic sources, so it is generally suitable for vegans and vegetarians.
The production source can vary between manufacturers — the Forkin app shows product-specific vegan and vegetarian signals where available, based on ingredient and label data. Always read the label for allergens.
