What it is

Oyster extract powder is made from the meat of oysters. The oysters are typically cooked, and then the liquid is concentrated and dried into a powder. This process captures the natural savory flavor of oysters.

Why it's used

Manufacturers use oyster extract powder to add a rich, umami, or savory flavor to foods. It is commonly found in Asian-inspired dishes, sauces, marinades, and frozen appetizers. It can also add a subtle seafood note.

Health notes

Oyster extract powder is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of natural glutamates, which contribute to its savory taste. International bodies like JECFA have evaluated oyster extract, but no specific numerical limits like ADI have been set for its use as a flavor enhancer. Evidence does not suggest adverse health effects at typical consumption levels.

Allergen info

Oyster extract powder is derived from shellfish, which is one of the 9 FDA major allergens. People with shellfish allergies should avoid products containing oyster extract.
