Product Description
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.

Product Application
Food Industry

Baked Goods Used in leavening agents (combined with sodium bicarbonate) for bread, cakes, and cookies to ensure uniform texture.

Meat Processing Added to sausages, hams, and processed meats to improve tenderness, juiciness, and yield.

Dairy Products Prevents caking in cheeses and powdered milk, extending shelf life.

Beverages & Condiments Acts as a pH stabilizer in juices, sauces, and dressings.
Industrial Applications

Water Treatment Functions as a corrosion inhibitor and scale inhibitor to prevent calcium/magnesium deposits in pipelines.

Cleaning Agents Enhances water softening and detergency in household and industrial cleaners.

Electroplating & Ceramics Stabilizes metal ions in electroplating baths and adjusts fluidity in ceramic glazes.
Usage Guidelines

Formulation Recommendations: Optimize leavening by balancing with carbonates (e.g., baking soda).

Storage: Store in sealed, dry conditions to prevent moisture absorption and caking.

Regulatory Compliance: Stay updated on regional regulations for legal adherence.
