Calcium glutamate

Calcium glutamate (CAS 19238-49-4) is the calcium salt of glutamic acid, also known as calcium diglutamate or calcium glutaminate. It carries no assigned E-number in the EU but is recognised under EC number 242-905-5. It is distinct from monosodium glutamate, providing both calcium mineral content and glutamate functionality in a single compound.

In food and nutrition applications, calcium glutamate delivers umami taste enhancement by activating glutamate receptors on the palate, functioning as a flavour potentiator without sodium. In pharmaceutical formulations, it serves as a calcium source in mineral supplements and oral preparations, where the glutamate counterion supports solubility compared to inorganic calcium salts.

Calcium glutamate is available in powder form for both food-grade and pharmaceutical-grade applications, with compliance assessed against FCC and relevant REACH registration requirements. Suppliers typically offer packaging in 25 kg bags or fibre drums. Buyers should confirm grade specification and documentation prior to procurement.
