Sodium Tripolyphosphate (STPP) — Food Grade
Allzone Trading supplies food grade sodium tripolyphosphate (STPP) to meat, poultry and seafood processors in Ontario, Quebec and across Canada. STPP is used in brines and marinades for protein solubilisation, water binding and cook-yield retention. Granulation, solubility and grade are confirmed against supplier documentation at quotation.

Technical & procurement detail
Functional role of sodium tripolyphosphate (stpp)+
STPP raises pH away from the isoelectric point of muscle protein and sequesters divalent metal ions, which allows myofibrillar protein to swell and hold added water. The practical result in processing is improved brine uptake, cook yield and sliced texture.
STPP is not interchangeable with other phosphates+
Sodium tripolyphosphate, sodium acid pyrophosphate and tetrasodium pyrophosphate are chemically distinct salts with different pH behaviour, solubility and function. They are frequently used together in blends, but substituting one for another at the same dosage changes both pH and performance. Specify the salt your formulation actually calls for.
Granulation drives dissolution+
Coarse granular STPP dissolves more slowly than fine powder and behaves differently in cold brine make-up. Undissolved phosphate in an injection brine causes filter and needle problems, so state your brine temperature and mixing time and the appropriate granulation will be requested.
Documentation and specification+
Functional values differ between producers and grades. Allzone confirms the applicable grade with the supplier before quoting and shares the technical data sheet and safety data sheet for the exact material offered, so the values you evaluate are the values you receive.
Frequently asked questions
Do you supply blended phosphate systems?+
Blends are available from suppliers. State the function you need and the salts your formulation currently uses, and the matching product and documentation will be requested.
Is food grade documentation provided?+
The supplier technical data sheet and safety data sheet for the exact grade quoted are shared, and food grade suitability is confirmed with the supplier before quotation rather than assumed here.
What packaging is available?+
Packaging is confirmed with the supplier at quotation for the grade and quantity discussed.
Can I request a technical data sheet?+
Yes — the supplier technical data sheet and safety data sheet are shared for the exact grade quoted.
Can you deliver to Ontario and Quebec food plants?+
Yes. LTL and FTL freight is arranged across Ontario, Quebec and Western Canada, with container-direct supply for repeat volumes.
