Frequently Asked Questions
Q
What is Tetrapotassium Pyrophosphate (TKPP) and what is its chemical formula?
Tetrapotassium Pyrophosphate (TKPP) is a condensed inorganic phosphate salt with the chemical formula K₄P₂O₇. It appears as a white powder or granular solid, is highly soluble in water, and produces an alkaline solution with a pH of 10.0–11.0 at 1% concentration.
Q
What are the main applications of TKPP in the food industry?
In the food industry, TKPP is used as an emulsifier, texture modifier, and chelating agent. It improves water retention in processed meat and seafood, prevents discoloration in canned fruits and vegetables, and enhances stability and expansion in dairy and frozen food products.
Q
How does TKPP function as a chelating agent?
TKPP acts as a strong chelating agent by binding to divalent and multivalent metal ions such as Ca²⁺, Mg²⁺, and heavy metal ions. This sequestration prevents unwanted reactions, improves formulation stability, and enhances the performance of active ingredients in both food and industrial applications.
Q
Is TKPP suitable for agricultural use?
Yes. TKPP serves as a valuable source of both potassium (K₂O ≥ 56%) and phosphorus (P₂O₅ ≥ 42%) in agriculture-grade formulations. It is used as a chelating agent in micronutrient formulations and helps improve nutrient stability in liquid fertilizers.
Q
What purity level and quality standards does your TKPP meet?
Our TKPP is manufactured with a minimum purity of ≥98.0%, with water-insoluble content ≤ 0.1%. It is produced under strict quality control conditions ensuring low impurity levels, uniform particle size, and reliable batch-to-batch consistency, meeting the requirements of global industrial and food-grade users.
Q
What packaging options are available, and is custom packaging supported?
TKPP is available in standard 25 kg bags. We also support customized packaging solutions, including OEM and ODM options, to meet the specific requirements of different markets and customers.
