Pentasodium triphosphate

Pentasodium triphosphate is a synthetic inorganic salt, a form of sodium triphosphate. It is produced industrially through chemical synthesis, typically by heating sodium carbonate and phosphoric acid.

It is commonly added to processed foods as a stabiliser and emulsifier. It helps to retain moisture, improve texture, and prevent ingredients from separating, particularly in processed meats, seafood, and dairy products.

Pentasodium triphosphate is an authorised food additive in Great Britain, listed on the Register of Food Additive Authorisations. European bodies like EFSA have evaluated its safety. JECFA has also evaluated it and set an acceptable daily intake. At typical consumption levels found in food, it is not considered to pose a health risk. Concerns have been raised about high phosphate intake from processed foods potentially affecting bone health and cardiovascular health, but this is a broader issue related to overall phosphate consumption rather than specific additives.
