Calcium diglutamate, sometimes abbreviated CDG and also called calcium glutamate, is a compound with formula Ca(C₅H₈NO₄)₂. It is a calcium acid salt of glutamic acid. CDG is a flavor enhancer (E number E623) — it is the calcium analog of monosodium glutamate (MSG). Because the glutamate is the actual flavor-enahancer, DCG has the same flavor-enhancing properties as MSG, but without the increased sodium content.^[1] As a soluble source of calcium ions, this chemical is also used as a first-aid treatment for exposure to hydrofluoric acid.^[2]
