What it is

Oyster extractives are derived from oysters, which are bivalve mollusks found in marine and brackish habitats worldwide. The extract is typically made by processing oyster meat to concentrate its natural savory flavors and nutrients.

Why it's used

Oyster extractives are used as a flavor enhancer, adding a rich, umami taste to foods. They are commonly found in savory dishes such as marinades, sauces, seasonings, broths, and processed seafood products.

Health notes

Oyster extractives are generally recognized as safe (GRAS) by the FDA for use as a flavoring agent. They are a natural source of minerals like zinc and selenium. International bodies like JECFA have evaluated oyster extractives, but no specific numerical limits were set. Evidence does not suggest adverse health effects at typical consumption levels.

Allergen info

Oyster extractives are derived from shellfish, which is one of the nine FDA major allergens. People with shellfish allergies should avoid products containing oyster extractives.
