Feed Inputs
Chemical name：Dihydrocalcium Phosphate, Monocalcium Phosphate Anhydrous
Molecular formula：Ca(H2PO4)2
Molecular Weight：Ca(H2PO4)2
White powder; specific gravity: 2.220; it is soluble in Hydrochloric Acid and Nitric Acid; slightly soluble in water (1.8% at 30℃); it contains free Phosphoric Acid and has the character of hygroscopicity. Its water solution is acidic.
In food industry, it is used as leavening agent, dough regulator, buffer, modifier, solidification agent, nutritional supplement, chelating agent, e.g., leavening agent for bake and cake; assistant fermentation agent and buffer for bread and biscuit; pectin curing agent, yeast food, modifier in meat product. When applied in fermentation, it can increase the fermentation capacity.
Packaging and storage
