MSG

Monosodium glutamate, printed as MSG or E621.

Matches personal ingredient preferences based on label evidence; not medical, allergy, or dietary safety advice

What the label is naming

MSG is monosodium glutamate, a flavor enhancer. Labels spell the full name, use MSG, or use E621. The acronym has a word boundary so it does not match inside other tokens. Yeast extract is a different entry; the catalog does not claim yeast extract is MSG.

Where it hides

Seasoning packets, instant noodles, ranch seasoning, and canned soup. It may be in the base product or only in a seasoning pouch. If the pouch list is missing, the verdict stays unknown rather than borrowing a similar soup.

Does the word glutamate inside another ingredient count?

The patterns are monosodium glutamate, the acronym MSG, and E621. Other glutamate chemistry is not inferred.
