4.Applications

Sodium tripolyphosphate is used in the food industry as an emulsifying agent and quality improver agent, for example, including processed meat processed seafood, processed cheeses, noodles product. Many governments regulate the quantities allowed in foods, as It can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists STPP as "generally recognized as safe. ".

The specific uses are as follows:

● Sodium tripolyphosphate is used for meat processing, synthetic detergent formulations, textile dyeing, also used as dispersing agent, solvent etc.

● It is used as soft water, also used in confectionery industry.

● It is used as power stations, locomotive vehicle, boiler and a fertilizer plant cooling water treatment, water softener.

● Modifier; emulsifier; buffer; chelating agent; stabilizer. Mainly for canned ham tenderization; canned broad beans in the Yuba softening. Can also be used as soft water, pH regulator and thickening agent.

● It is used for synergist for soap and preventing bar soap grease precipitation and bloom. It has strong emulsification of lubricating oil and fat. It can be used for adjusting the value of pH of buffer liquid soap. Industrial water softener. Pre tanning agent. Dyeing auxiliaries. Paint, kaolin, magnesium oxide, calcium carbonate, such as industrial in the preparation of suspensions of dispersant. Drilling mud dispersant. In paper industry used as anti oil agents.

● Sodium tripolyphosphate is used for detergents. As additives, synergist for soap and preventing bar soap crystallization and bloom, industrial water soft water, pre tanning agent, dyeing auxiliaries, well digging mud control agent, paper with oil on preventing agent, paint, kaolin, magnesium oxide, calcium carbonate, such as hanging floating fluid treatment effective dispersant. Food grade sodium tripolyphosphate as a variety of meat products, food improver, the clarification of the beverage additives.

Quality improver to improve food complexed metal ions, pH value, increasing ionic strength, thereby improving food focus and water holding capacity.
