Physical and chemical properties	Phosphate is one of the natural ingredients of almost all foods. It is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid, which is very important in inorganic chemistry, biochemistry and biogeochemistry. Phosphate is one of the natural ingredients of almost all foods. It is widely used in food processing as an important food ingredient and functional additive. The naturally occurring phosphate is phosphate rock (containing calcium phosphate), which reacts with phosphate rock with sulfuric acid to produce calcium dihydrogen phosphate and calcium sulfate that can be absorbed by plants, which can produce phosphate. Phosphate can be divided into orthophosphate and polycondensation phosphate: The phosphate used in food processing is usually sodium salt, calcium salt, Potassium salt, and iron salt and zinc salt as a nutritional fortifier, commonly used food There are more than 30 varieties of grade phosphate. Sodium phosphate is the main consumption type of domestic food phosphate. With the development of food processing technology, the consumption of Potassium phosphate is also increasing year by year.
