Summary: It is an inorganic compound with the chemical formula Na(PO₃)s. It is a white crystalline powder that is easily soluble in water. Usage: Sodium trimetaphosphate can be used as a starch modifier in the food industry; Water retaining agent for meat processing; Dairy products such as ice cream and cheese
Stabilizers and dispersants to prevent food discoloration and prevent the breakdown of vitamin C. At the same time, it is also a raw material for producing Vc phosphate ester.
TD:
Research and testing
Sodium tripolyphosphate is used for starch denaturation, and the process of cross-linking starch requires hydrolysis to form sodium tripolyphosphate before generating starch phosphate ester. Sodium triphosphate can be used in the building materials industry for the production of gypsum boards, enhancing their strength and toughness, improving their waterproof and moisture-proof capabilities, and preventing deformation. Used as a softener in water quality treatment.
