What it is

Cultured onion is a fermented product made from onions. Fermentation uses microorganisms to break down sugars in the onion, creating new flavors and textures. This process can also extend the onion's shelf life.

Why it's used

Manufacturers use cultured onion to add a savory, umami flavor to foods. It can provide a more complex taste than raw or cooked onions alone. It is often found in savory dishes like entrees, pasta dinners, and sides.

Health notes

Cultured onion is generally recognized as safe (GRAS) by the FDA for use in food. Fermented foods, including those with cultured ingredients, are often studied for their potential benefits to gut health. However, specific health effects of cultured onion at typical intake levels have not been extensively studied. JECFA has evaluated fermented foods but has not set specific limits for cultured onion.

Allergen info

Onion is not one of the 9 FDA major allergens. It does not contain gluten.
