Airophos 4KP is a tetra potassium pyrophosphate based – is a salt composed of pyrophosphate ions.
Is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent. Its toxicity is approximately twice that of table salt when ingested orally. They produce metallic complexes with metallic ions. The magnesium ion in this instance is inactivated, or sequestered. The product formed does not precipitate from solution. Is best for magnesium ions whereas sodium hexametaphosphate is best for calcium ions. The inclusion of pyrophosphate with salt enhances protein hydration and dissolution, resulting in increased yields and firm reformed products on cooking
Airophos 4KP is a colourless, transparent crystalline chemical compound with the formula Na4P2O7
