Food phosphate · Potassium salt · INS 450(v)
TKPP is a highly water-soluble alkaline phosphate used in selected food formulations for emulsification, sequestration, texture support and process control. Bespring supplies food grade TKPP for international industrial buyers.
Include quantity, destination, application and required compliance documents for a useful quotation.
Product overview
Tetrapotassium pyrophosphate (TKPP), also called tetrapotassium diphosphate or potassium pyrophosphate, is the potassium salt of pyrophosphoric acid. Its chemical formula is K4P2O7, its CAS number is 7320-34-5, and its international food additive designation is INS 450(v).
TKPP is hygroscopic and highly soluble in water. Its combination of alkalinity, phosphate functionality and metal-ion binding makes it useful in carefully designed food-processing systems. The appropriate dosage and legal use must be determined for the specific food category and destination market.
Functional roles
TKPP can perform several functions in a formulation. Actual performance depends on the complete phosphate system, raw materials, process conditions, dosage and target product attributes.
TKPP can bind selected metal ions and support process control in food systems where mineral interactions influence stability, appearance or equipment performance.
In suitable protein, starch and dairy systems, TKPP may contribute to emulsification, water management, yield and finished-product texture.
Food industry uses
These are formulation starting points rather than universal usage claims. Buyers should verify technical suitability, permitted use level and labeling requirements.
Used in selected ground-meat and ham-sausage phosphate systems to support water retention, yield and texture.
May be combined with other condensed phosphates for mineral control and quality objectives in aquatic-product processing.
Alkaline phosphate functionality can support texture, processing tolerance and yield in suitable noodle formulations.
Used in selected stabilizer and emulsifier systems where overrun, consistency and process performance are being optimized.
Sequestration and emulsification functions may support mineral and protein management in suitable dairy applications.
May be evaluated in carefully controlled phosphate systems intended to support processing and product appearance.

Qualification support
Certificates and management-system documents are time-sensitive. Ask for current, applicable copies and verify the product name, site, scope, issuer and validity dates during supplier qualification.
Current specification, technical data sheet, safety data sheet and a representative or batch-specific certificate of analysis.
Request the HACCP, Kosher and Halal documents applicable to the offered product and production or packing site.
Request the current ISO certificate and scope, together with traceability or quality questionnaires required by your approval process.
Storage & handling
Buyer questions
TKPP is used in selected formulations as an emulsifier, sequestrant, texturizer and alkaline phosphate. Potential applications include processed meat, seafood, noodles, dairy systems, frozen desserts and canned foods, subject to trials and local regulations.
Yes. Tetrapotassium pyrophosphate, tetrapotassium diphosphate and potassium pyrophosphate are commonly used names for K₄P₂O₇, CAS 7320-34-5 and INS 450(v).
