Direct product answer
What is food grade potassium metaphosphate?
Food grade potassium metaphosphate (KMP) is a potassium phosphate salt identified by CAS 7790-53-6 and the general formula KPO3. The supplied grade is a white powder intended for evaluation in food-processing systems that need phosphate functionality without sodium.
The material can support emulsification, moisture retention, water softening, metal-ion sequestration, texture adjustment, color protection and oxidative-stability objectives. Performance depends on the complete formulation, process, dosage and destination-market rules.
Food formulation uses
Where is potassium metaphosphate used?
The supplied product information identifies the following application areas and functional targets. Treat them as formulation starting points, not universal performance or permission claims.
Cheese systems
May support fat emulsification, metal-ion control and microstructure adjustment in selected cheese formulations.
Evaporated milk
Can be assessed for mineral control, buffering-related process stability and emulsification in qualified dairy systems.
Aquatic seasonings
The supplied application guidance highlights microstructure modification and related quality control in selected aquatic seasoning systems.
Water conditioning
Metal-ion chelation and water-softening functionality may help manage process-water interactions in the complete formulation.
Quality protection
May contribute to color protection, antioxidant systems and preservation objectives when permitted and validated.

| Arsenic (As) | % | ≤0.0003 |
| Heavy metals (as Pb) | % | ≤0.001 |
| Fluorine (F) | % | ≤0.001 |
| Lead (Pb) | % | ≤0.0002 |
| Viscosity (as stated on supplied sheet) | 10 | ≤10 |
| pH value | — | 3.0–5.0 |
| Appearance | — | White powder |
Method check: The supplied viscosity row does not define a complete unit or test method. Request the signed specification and confirm this parameter with Bespring before using it as an acceptance criterion.
Buyer qualification
What should a KMP buyer confirm?
A useful approval compares the offered source with the actual food process and market, rather than relying on the product name alone.
Identity and specification
Confirm CAS number, formula, P2O5, pH, contaminants, appearance and the method behind every critical test.
Current documents
Request specification/TDS, SDS, representative or batch COA and applicable HACCP, Kosher, Halal and ISO documents.
Application trial
Evaluate KMP in the real formula and process for solubility, mineral interactions, texture, color, flavor and shelf-life targets.
Storage and handling
Keep KMP cool, dry and sealed
- TemperatureThe supplied guidance states storage at no more than 30°C.
- EnvironmentProtect sealed bags from direct sunlight, heat, humidity and contamination in a ventilated area.
- Workplace controlsFollow the current SDS and site procedures for dust handling and personal protection.
Buyer questions
Food grade potassium metaphosphate FAQ
What is potassium metaphosphate used for in food?
It is evaluated in selected meat, cheese, evaporated-milk and aquatic-seasoning systems for functions such as emulsification, moisture management, metal-ion sequestration, texture adjustment, color protection and process stability.
Is KMP sodium-free?
The formula KPO3 contains potassium rather than sodium. This does not by itself establish a finished-food nutrition or labeling claim; review the complete formula and local rules.
What are the packing and minimum order?
The supplied reference is 25 kg per bag, 20 metric tons per 20-foot container and a 500 kg minimum order. Confirm current pallet, liner and loading details in the quotation.
What information is needed for a KMP quotation?
Provide the intended food application, target specification and test methods, quantity, packaging, destination port, required documents and delivery schedule.
