Polyphosphates
What you need to know
Polyphosphates stabilise instant noodles, processed cheese and cured meats.
They share the total-phosphate daily limit with the other phosphate additives.
Regulators permit them with maximum levels.
Where it stands, by region
The same additive can be approved in one country and banned in another. This is the divergence that matters most.
