1. In the food industry: Sodium Pyrophosphate Decahydrate (TSPP) is widely utilized as a high-quality improver, pH regulator, and metal ion chelating agent. Its specific applications include:
2. Meat and Seafood Processing: TSPP is highly effective at breaking down actomyosin, releasing myosin, and shifting the pH away from the isoelectric point. This significantly enhances water retention, improves texture (making the meat tender and bouncy), and stabilizes emulsions. It is widely used in sausages, ham, meatballs, and prepared steaks to prevent oil and water separation during cooking.
3. Beverages and Dairy Products: Acting as a buffering agent and stabilizer, it maintains consistent pH levels and prevents protein precipitation. It is commonly added to fruit-flavored drinks, protein beverages, lactic acid bacteria drinks, and coffee to ensure uniform texture and extend shelf life.
4. Frozen Rice and Noodle Products: As a moisture-retaining agent, it prevents frozen dumplings, glutinous rice balls, and fresh noodles from cracking or losing moisture during freezing and boiling, thereby improving their chewy texture and appearance.
5. Canned Foods: Sodium Pyrophosphate Decahydrate helps stabilize natural pigments and prevents the discoloration of canned fruits, vegetables, and meats. Additionally, it chelates metal ions to inhibit fat oxidation and spoilage, keeping the canned food fresh and visually appealing.
6. Bakery and Instant Cereals: In baked goods, it can be used as a leavening agent component to improve the volume and crumb structure. In instant cereals like rolled oats, it acts as a moisture-retaining agent to maintain optimal texture.

Environmental conditions: Cool, dry, well-ventilated warehouse; temperature 5-30℃; avoid high temperatures and direct sunlight; prohibit humid environment. This product is prone to deterioration in dry air and will absorb moisture and form lumps when damp.
Separate storage: Keep away from strong oxidants; do not store together with strong acids; stack separately.
Q: Product appearance?
A: Colorless transparent crystals or white crystalline powder; it will deteriorate and lose water in a dry environment, and will form lumps when exposed to moisture.
Q: Water solubility and pH?
A: Easily soluble in water, insoluble in ethanol; 1% aqueous solution has a pH of approximately 10-10.2, showing strong alkalinity.
Q: Stability?
A: Stable at room temperature; loses crystalline water when heated to 100℃; the water solution will be converted to disodium hydrogen phosphate when boiled; avoid contact with strong oxidants and strong acids.
Q: Common purity grades?
A: Industrial grade, food grade, reagent grade (AR); COA and MSDS can be provided.
Q: MOQ?
A: Industrial grade regular MOQ: 1 ton; small batch samples can be provided, with sample shipping cost to be paid by the customer.
Q: Delivery time?
A:For stock items, it takes 3 to 5 working days; for customized specifications, it takes 7 to 15 working days.
