What it is

Dry onions are dehydrated onions, typically made by slicing fresh onions and then drying them using air or vacuum dehydration. This process removes most of the water content, concentrating their flavor and extending their shelf life. They are available in various forms, including flakes, granules, and powders.

Why it's used

Manufacturers use dry onions to add concentrated onion flavor to a wide variety of foods without the moisture and perishability of fresh onions. They are common in dry mixes, spice blends, sauces, processed meats, and baked goods. Their convenience and consistent flavor make them a popular choice for food production.

Health notes

Dry onions are generally recognized by the FDA as safe (GRAS) for use in food. They contain various nutrients and antioxidants found in fresh onions. International bodies like JECFA have evaluated onions and their components. At typical consumption levels in food, they are not associated with adverse health effects.

Allergen info

Onions are not one of the nine major allergens recognized by the FDA. They do not contain gluten.
