Application OF STPP Sodium Tripolyphosphate

In Food:

The uses of stpp include using it as a preservative. Sodium Tripolyphosphate STPP can be used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture. Pet food and animal feed have been known to be treated with Sodium tripolyphosphate stpp , serving the same general purpose as it does in human food. 

In Tech:

The majority of STPP Sodium tripolyphosphate is consumed as a component of commercial detergents.

Other uses include "ceramics (increase viscosity of the glazes upto a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze."STPP is used as a polyanion crosslinker in polysaccharide based drug delivery
