Applications
DM DSP 103 may be categorized in sodium orthophosphate that is widely used in food, cosmetics, pharmaceutical, aquaculture (Feed grade), printing and dyeing, also as softening agent for boiler, and other fields.
In food ,DM DSP 103 is a multifunctional ingredient that can be used to improve nutritional value and cooking performance in food production. It could be an acid regulator due to its weak alkaline (ph value 8.4 to 9.6 with 1% solution); used as an anticaking agent and moisture retention agent for its hygroscopic; as a quality improver for condensed milk; as a stabilizer for dairy products, meat and fish products; a component in mixed salt for curing, and etc.
