Sodium tripolyphosphate Product Introduction

Sodium tripolyphosphate, also known as pentasodium phosphate, sodium pyrophosphate, STPP, or pentasodium tripolyphosphate, is a white, crystalline powder with good flowability. It has a relative molecular mass of 367 (Chemicalbook 86), a melting point of 622℃, and is readily soluble in water, whose aqueous solution is alkaline. It is commonly used in food as a moisture retainer, quality improver, pH adjuster, and metal chelating agent.

Physical & Chemical Properties

Product Applications

1. Uses: A highly efficient water softener used in power plants, locomotives, boilers, and fertilizer plants for cooling water treatment. It has a strong ability to complex Ca2+, chelating 19.5g of calcium per 100g. Furthermore, due to the chelating and adsorption-dispersing effects of SHMP, it disrupts the normal growth process of calcium phosphate crystals, preventing the formation of calcium phosphate scale. A dosage of 0.5mg/L can prevent scaling by 95%–100%.

2. Uses: Texture improver; emulsifier; buffer; chelating agent; stabilizer. Primarily used for tenderizing canned ham and softening the skin of canned broad beans. It can also be used as a water softener, pH adjuster, and thickener.

It can also be used as a water softener, pH adjuster, and thickener. 3. Uses: Sodium tripolyphosphate is used in detergents as an additive, soap enhancer, and to prevent soap crystallization and blooming. It is also used in industrial water softeners, leather pretanning agents, dyeing auxiliaries, oil well mud control agents, papermaking oil stain preventers, and as an effective dispersant for treating suspensions of paints, kaolin, magnesium oxide, calcium carbonate, etc. Food-grade sodium tripolyphosphate can be used as a food improver for various fish and meat products and a clarifying agent for beverages.

4. Uses: As a quality improver, it increases the complexation of metal ions, pH value, and ionic strength in food, thereby improving the binding force and water-holding capacity of food. In my country, it is permitted for use in dairy products, fish products, poultry products, ice cream, and instant noodles, with a maximum usage of 5.0 g/kg; in canned goods, fruit juice (flavored) beverages, and plant protein beverages, the maximum usage is 1.0 g/kg.
