What is Sodium Acid Pyrophosphate (SAPP)?
Sodium Acid Pyrophosphate (SAPP) is an inorganic compound with the chemical formula Na₄P₂O₇. It is a white crystalline powder with high sequestering properties, which makes it useful in a variety of industrial and food applications. SAPP is commonly used as a dispersing agent, water treatment chemical, and chelator to bind metal ions. It is also used in the food industry as a sequestering agent in processed foods and beverages.
Key Features & Benefits:
✅ Excellent Sequestering Properties – Binds with metal ions to prevent spoilage and maintain stability
✅ Highly Effective Water Softener – Used in detergents and water treatment processes
✅ Food-Grade Safety – Safe for use in food products as a food additive (E450)
✅ Improves the Texture of Processed Foods – Enhances the texture and quality of canned foods and beverages
✅ Wide Industrial Applications – Used in ceramics, detergents, and textile industries
✅ Cost-Effective & Versatile – Available for bulk use at competitive prices
