Calcium hydrogen phosphate is an inorganic substance with the chemical formula CaHPO4. It is a white monoclinic crystalline powder, odorless and tasteless, easily soluble in dilute hydrochloric acid, dilute nitric acid, acetic acid, slightly soluble in water (100°C, 0.025%), insoluble For ethanol, it usually exists in the form of dihydrate (CaHPO4·2H2O). Its dihydrate is stable in the air. When heated to 75ºC, it starts to lose crystal water and become anhydrous, and at high temperature it becomes pyrophosphate.

1. As a fortifier (calcium supplement) and leavening agent, my country stipulates that it can be used for biscuits, infant formula food, and the maximum use amount is 1.0g/kg; it can also be used as a quality improver for fermented noodles, according to production needs Use in moderation.
2. As food and feed additives to supplement the phosphorus and calcium elements in poultry and livestock feed.
3. In the food industry, it is used as a bulking agent for biscuits and milk replacers. The usage amount is according to normal production needs. Also used as a yeast culture agent for bread manufacturing. It is also used as a dough improver and nutritional supplement. It can be used as a feed additive to supplement phosphorus and calcium in poultry and livestock feed.
4. Used as an auxiliary feed for poultry, it can promote the digestion of feed and increase the weight of poultry to increase meat production, milk production and egg production. It can also treat livestock rickets, rickets, anemia, etc.
5. Used as analytical reagent, plastic stabilizer, food and feed additive, and also used in glass industry.
