High-Quality Sodium Tripolyphosphate STPP for Food Industry Applications

Product Description

Product Description
Sodium Tripolyphosphate (STPP) is an inorganic compound. It is a white crystalline powder or granular material, highly soluble in water, and widely used as a versatile industrial and food-grade additive. STPP is valued for its chelating, emulsifying, and pH-buffering properties, making it a critical ingredient in detergents, food processing, and water treatment. It complies with global standards such as FCC (Food Chemicals Codex) and ISO certifications.Key Features
Chelating Agent: Binds metal ions (e.g., calcium, magnesium) to prevent scaling and improve cleaning efficiency.
Water Softening: Enhances detergent performance by softening hard water. Emulsion Stabilizer: Maintains texture and moisture in food products.
pH Regulation: Acts as a buffering agent in industrial processes.
Cost-Effective: Improves product performance at low concentrations.Product Parameters
