Is Malt Extract / Malt Flavoring Gluten-Free?
Malt extract and malt flavoring are made from barley and are NOT gluten-free. This is one of the most common hidden gluten sources in cereals and candy.
Anything with "malt" in the name — malt extract, malt syrup, malt flavoring, malted milk, malt vinegar — comes from barley, one of the three gluten grains. This is the most common hidden gluten ingredient in otherwise innocent-looking products.
Classic gotchas: corn flakes and crisped-rice cereals (malt flavoring), malted milkshakes and malt balls (Whoppers, malted milk powder), some chocolate drinks, certain crackers, and malt vinegar on fish and chips.
US allergen law does not require barley to be called out the way wheat is, so "malt flavoring" can sit quietly in an ingredient list with no warning. Train your eye to stop at the word "malt" — it is the single highest-value word to scan for on any label.
How to check the label
- Scan every label for the word "malt" — extract, syrup, flavoring, malted milk, malt vinegar are all barley
- Check cereals especially: many rice/corn cereals use malt flavoring
- Distilled vinegars are safe; malt vinegar is not
