Description
Calcium dihydrogen phosphate (CAS 7758-23-8) is an inorganic calcium phosphate salt, commercially known as AMCP, calcium biphosphate, and PY-RAN. It carries the E-number E341(i) and is classified under HS code 31031010.
In food manufacturing, it functions as a leavening acid in baking powders, releasing carbon dioxide when heated to produce consistent dough rise. In agricultural feed formulations, it delivers bioavailable phosphorus and calcium to support bone mineralisation in livestock. It also acts as a pH buffer and chelating agent in processed food systems, binding free metal ions that would otherwise accelerate oxidation.
Calcium dihydrogen phosphate is supplied as a white crystalline powder in food-grade and feed-grade specifications, compliant with E341(i) purity criteria, FCC standards, and REACH registration requirements. Standard packaging includes 25 kg bags, with bulk options available on request for industrial volumes.
