Food-grade sodium pyrophosphate is a\u00a0white crystalline powder or granular solid, highly soluble in water but insoluble in alcohol. It has a\u00a0strong alkaline pH (9.9\u201310.7 in 10 g\/L solution)\u00a0and acts as a\u00a0chelating agent for metal ions. The anhydrous form melts at\u00a0880\u00b0C, while the decahydrate loses water at\u00a0100\u00b0C. It is\u00a0hygroscopic, absorbing moisture from air, and hydrolyzes to\u00a0disodium phosphate\u00a0when boiled in water<\/p>\n

As a food additive, it works as a quality improver. In meat products, it retains moisture, improves tenderness and juiciness. In seafood, it prevents discoloration. Used in dairy to stabilize emulsions, in baked goods to enhance texture. Also functions as a sequestrant in beverages, with usage levels generally 0.05% – 0.5%, following food additive regulations.<\/p>\n

Packed in polyethylene – lined woven bags, paper bags, or composite plastic bags, with common net weights like 25kg\/50kg. Store in a cool, dry, ventilated warehouse. Avoid moisture, direct sunlight, and contact with acids. Keep sealed to prevent caking and quality deterioration. Shelf life is around 24 months under proper storage conditions.<\/p>","protected":false},"excerpt":{"rendered":"
