Popular questions
What foods contain calcium diglutamate?
It’s used as a flavor enhancer in savory processed foods such as soups and broths, sauces and gravies, snack foods and seasonings, instant noodles, ready meals, and some processed meats—often in reduced‑sodium products as an alternative to MSG. On labels it may appear as “calcium diglutamate” or E623.
What is the e number of calcium diglutamate?
E623.
Is glutamic acid the same as glutamine?
No. Glutamic acid (E620) is an amino acid, while glutamine is its amide derivative; they’re related but chemically distinct and serve different roles.
Is glutamate the same as glutamic acid?
They’re the deprotonated (glutamate) and protonated (glutamic acid, E620) forms of the same molecule; at typical physiological and food pH, glutamate predominates.
Is glutamic acid acidic or basic?
Acidic—glutamic acid has two carboxyl groups and is largely present as its negatively charged form (glutamate) at neutral pH.
Is glutamic acid the same as glutamate?
Yes—glutamate is the ionized form of glutamic acid (E620); which term is used depends on pH or whether it’s in a salt (e.g., MSG).
Are glutamate and glutamic acid the same?
Yes—they refer to the same substance in different forms: glutamic acid is the acid, and glutamate is its anion or salt.
