Calcium dihydrogen phosphate is a colorless, triclinic, granular, or crystalline inorganic compound with a strong acidic taste. When pure, it does not absorb moisture and contains trace impurities. It can lose crystalline water at 100 ° C and decompose at 200 V. It is soluble in dilute hydrochloric acid, dilute nitric acid, and dilute acetic acid, slightly soluble in water, and insoluble in ethanol.
effect
Calcium dihydrogen phosphate is widely used as a feed additive for aquaculture animals and livestock breeding animals. It is used as a quality improver such as a leavening agent, dough conditioner, buffer, nutritional supplement, emulsifier, stabilizer, etc. It can improve the complexing metal ions, pH value, and ion strength of food, and can improve the adhesion and water holding capacity of food.
Limited usage
According to China's regulations, the amount used for bread, biscuits, and baking powder is calculated as 4g/kg based on phosphoric acid; The dosage in solid drinks is 8g/kg. It can also be used as an analytical reagent, refractory industry, wastewater treatment, plastic fixing agent, etc. From this, it can be seen that calcium dihydrogen phosphate has a wide range of industrial applications and occupies an important position in the national economy.
