Calcium diglutamate
Chemical compound / From Wikipedia, the free encyclopedia
Calcium diglutamate, sometimes abbreviated CDG and also called calcium biglutamate, 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-enhancer, CDG has the same flavor-enhancing properties as MSG but without the increased sodium content.[1] Notably, only the L isomer is used in flavouring as D-glutamate does not have an umami/savoury flavour.[2][3]
