1. Chemical Name: Calcium Dihydrogen Phosphate, Monocalcium Phosphate Molecular Formula: Ca (H2PO4)2·H2O, Ca (H2PO4)2
2. Molecular Weight: 252.07
3. Characteristics: White crystalline powder or flaky crystals, specific gravity 2.220, loses crystal water at 100°C, soluble in hydrochloric acid and nitric acid, slightly soluble in water (1.8%). Generally contains free phosphoric acid, hygroscopic (30°C), aqueous solution is acidic (pH 3).
4. Quality Standards: HG2927-1999, FCC-V, E341(i)
5. Uses: In the food industry, it is used as a leavening agent, dough conditioner, buffer, tissue improver, firming agent, nutritional supplement, chelating agent, etc. For example, as a leavening agent for baked goods and pastries. It serves as a fermentation aid, buffer, and pectin firming agent (gelling action) in bread and biscuits, as well as a tissue improver for yeast and meat products. In brewing, it increases saccharification power and enhances fermentation capacity.
