Product Description

Chemical Properties
Formula: Na2H2P2O7, a member of the pyrophosphate family, formed by the condensation of two phosphate groups.
pH Regulation: Aqueous solutions are weakly acidic (pH ~4-5), making it suitable as an acidity regulator in food.
Chelation: Binds metal ions (e.g., Ca², Mg², Fe²/³), inhibiting oxidation and discoloration, thereby extending product shelf life.
Physical Properties
Appearance: White crystalline powder, highly soluble in water, low hygroscopicity for easy storage and processing.
Thermal Stability: Stable under high temperatures, ideal for baking and heat-intensive processes.
