Food grade phosphate · Potassium salt · CAS 13845-36-8
Potassium tripolyphosphate is a condensed potassium phosphate evaluated in selected food systems as an emulsifier, moisture-retention agent, sequestrant, stabilizer, texture modifier, binder and quality-protection aid.
Include your food application, target specification, quantity, destination and required documents.

Direct product answer
Food grade potassium tripolyphosphate (KTPP) is a condensed potassium phosphate with formula K5P3O10 and CAS number 13845-36-8. The supplied grade is a white powder with a reference assay of at least 90.0%.
KTPP is not the same material as sodium tripolyphosphate (STPP) or tetrapotassium pyrophosphate (TKPP). Buyers should qualify the exact chemical identity, grade, specification and functional performance required by their process.
Functional roles
The supplied application information identifies several possible functions. Actual results depend on the complete phosphate system, dosage, raw materials, process and regulatory limits.
KTPP may be evaluated where protein, fat and water interactions affect process yield and finished texture.
Phosphate functionality may support metal-ion control, stabilization and selected color or oxidative-stability objectives.
Food application screening
The supplied sheet describes KTPP by its functional roles rather than a closed list of food categories. Qualification should therefore start with the intended process and measurable acceptance criteria.
Screen emulsification, water retention, binding, yield and texture under the real salt, protein and temperature conditions.
Evaluate mineral interactions, emulsification, stability, flavor and texture in the complete dairy formulation.
Test moisture management, appearance and texture while controlling dosage, labeling and destination-market limits.
Compare KTPP alone and in permitted blends for solubility, pH, sequestration and functional performance.
Measure color retention under realistic processing and storage; do not infer finished-product shelf life from ingredient identity alone.
Define target outcomes, control formulation, sampling plan and test method before moving from bench to plant trial.

Buyer questions
No. KTPP is potassium tripolyphosphate, K5P3O10, CAS 13845-36-8. TKPP is tetrapotassium pyrophosphate, K4P2O7, CAS 7320-34-5. They require separate specifications and trials.
The supplied sheet states K5P3O10 content of at least 90.0%. Confirm the current signed specification and test method for the offered batch.
The reference is 25 kg per bag, 22 metric tons per 20-foot container and a 500 kg minimum order. Confirm current pallet, liner and loading details.
