Overview

E620 - Glutamic acid

Glutamic acid (E620) is an amino acid used as a flavor enhancer to boost the savory “umami” taste in foods. It occurs naturally in many foods and is also produced for use in seasonings, soups, snacks, sauces, and other savory products.

E635 - Disodium 5'-ribonucleotide

Disodium 5'-ribonucleotide (E635) is a flavor enhancer used to boost savory, umami taste in foods. It is typically a blend of two nucleotides: disodium inosinate and disodium guanylate. You’ll see it in many salty or meaty-tasting snacks, soups, and sauces.

Popular questions

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.
