Onion powder
Onion powder is more concentrated than fresh onion and is moderately flagged, appearing as a hidden ingredient in many packaged foods.
Like garlic powder, the drying and concentrating process may make onion powder harder to tolerate than fresh onion for some people.
-
Fresh vs. dried — fresh onion is generally considered lower risk, while onion powder concentrates the plant's compounds into a smaller volume, which some people with histamine sensitivity find more problematic
-
Ubiquitous in seasoning blends — onion powder is one of the most common ingredients in packaged soups, spice mixes, marinades, and snack foods, making it easy to consume regularly without realizing it
