Triphosphates
What you need to know
Triphosphates keep cured meats juicy by binding water, and stabilise processed seafood.
Like all added phosphates they count toward one shared daily limit, which heavy consumers of processed food can approach.
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.
