What it is

Lacresin is a synthetic flavoring substance that mimics the taste of butter or cream. It is chemically known as diacetyl. It is produced through chemical synthesis.

Why it's used

Lacresin is used to add or enhance buttery or creamy flavors in a variety of foods. It is commonly found in baked goods like cookies and biscuits, as well as in popcorn and snack foods.

Health notes

In the US, diacetyl is generally recognized as safe (GRAS) by the FDA for use as a flavoring substance. However, concerns have been raised about potential respiratory issues, particularly for workers exposed to high concentrations in manufacturing settings. Regulatory bodies like EFSA have also evaluated diacetyl. While generally considered safe for consumers at typical food levels, its use is monitored.

Allergen info

Lacresin is not derived from any of the 9 FDA major allergens. It does not contain gluten.
