Direct product answer
What is food grade dipotassium phosphate?
Food grade dipotassium phosphate (DKP), also called dipotassium hydrogen phosphate or dibasic potassium phosphate, has formula K2HPO4, CAS number 7758-11-4 and INS number 340(ii).
The supplied grade has a reference assay of at least 98.0%. DKP is distinct from monopotassium phosphate and tripotassium phosphate; its alkalinity, pH range and functional behavior should be assessed in the actual formulation.
Functional roles
Why is DKP used in food processing?
DKP can perform more than one role. The final result depends on dosage, the complete mineral and protein system, process conditions and the destination market.
Water and emulsion management
The supplied application information identifies water retention and emulsification; JECFA also lists buffering, sequestration and yeast-food functions.
- Moisture-retention support
- Emulsification in selected formulations
- Mineral-ion sequestration and culture support
Food application screening
Common food grade DKP applications
These application areas come from the supplied product information and recognized functional-use context. Confirm legal use and validate performance for the exact product.
Meat products
Evaluate water retention, binding, emulsion stability, yield, texture and flavor in the real salt and protein system.
Cheese and dairy
May support buffering, mineral balance, emulsification and processing stability in qualified dairy formulations.
Beverages
Can be assessed for pH buffering and potassium-phosphate contribution while controlling taste, clarity and compatibility.
Culture and fermentation
JECFA identifies yeast-food functionality; qualify nutrient contribution, pH response and growth performance in the actual medium.
Moisture management
Measure water retention and finished-product stability rather than assuming a universal result from ingredient identity.
Blend development
Compare DKP alone and in permitted phosphate systems for solubility, pH, mineral interactions and sensory impact.

Buyer questions
Food grade DKP FAQ
What is the difference between DKP and MKP?
DKP is K2HPO4 and INS 340(ii); MKP is KH2PO4 and INS 340(i). Their potassium-to-phosphate ratio, solution pH and formulation behavior differ.
What is food grade DKP used for?
It is evaluated as a buffer, acidity regulator, sequestrant, moisture-retention agent, emulsifier and culture nutrient in selected meat, cheese, beverage and fermentation systems.
What is the reference assay?
The supplied sheet states at least 98.0% K2HPO4. Confirm the current signed specification and batch COA for the offered supply.
What are the packing and minimum order?
The reference is 25 kg per bag, 22 metric tons per 20-foot container and a 500 kg minimum order. Confirm current liner, pallet and loading details.
What details are needed for a DKP quotation?
Provide the food application, target specification, quantity, packing, destination, required documents and requested delivery date.
