https://en.wikipedia.org/wiki/Flavor
Note the statement: ". . . first determine the source of the flavoring before consuming the food."
The corn allergy population must contact food manufacturers to inquire about the presence of corn/corn derivatives in their products (often added under "natural flavors"). However, many manufacturers claim "proprietary formulations;" and will not release this information to the public. For the protection of all consumers, food manufacturers should be required to release this information--UPON REQUEST--in an effort to avoid a potentially life-threatening allergic reaction.
Contact me if a food manufacturer refuses to disclose if corn/corn derivatives are in their product(s), upon request.
Corn-derived ANYTHING (dextrose, citric acid, ascorbic acid, etc.) can be fatal to the anaphylactic corn allergy population. Medical professionals, as well, must understand the critical difference between dextrose and corn-derived dextrose, citric acid and corn-derived citric acid, ascorbic acid and corn-derived ascorbic acid, etc.
Citric Acid:
"The source of sugar is corn steep liquor, molasses, hydrolyzed corn starch or other inexpensive sugary solutions."
https://en.wikipedia.org/wiki/Citric_acid
Maltodextrin:
"Maltodextrin can be enzymatically derived from any starch. In the US, this starch is usually corn; in Europe, it is commonly wheat."
https://en.wikipedia.org/wiki/Maltodextrin
Ascorbic Acid:
"Another wake up call about ascorbic acid – it is synthesized from corn syrup."

Dextrose (Corn Sugar):
DEXTROSE (CORN SUGAR): FDA
FEDERAL REGULATION, GRAS - 184.1857
https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=184.1857Enriched Foods:
The corn allergy population must avoid "enriched" foods, due to processing with added corn/corn derivatives. "Enriched" usually indicates the probable presence of corn.
