Function of tetrasodium diphosphate and trisodium diphosphate in meat

What is the difference between the function of tetrasodium diphosphate and trisodium diphosphate in meat?

I have 2 phosphate ingredients that only differ in that, one has tetrasodium diphosphate and the other has trisodium diphosphate?
Sodium content is the same according to the TDS.

i gues they are same products just with differents names.

please check product datasheets.

There is no tetrasodium diphosphate but pyrophospate…

Trisodium is more soluble than tetrasodium which the tetrasodium often forms complexes with divalent ( Ca and Mg ) present in water reducing its emulsifying effect on meat.
