Butter Emulsion

Butter emulsion is a flavoring ingredient designed to give foods the taste and aroma of butter. It is typically a blend of flavor compounds, often suspended in a water or oil base, sometimes with the help of emulsifiers. These compounds can be derived from natural sources or created synthetically.

Manufacturers add butter emulsion to products to impart a rich, buttery flavor without using actual butter. This can help reduce costs, extend shelf life, or create dairy-free options. It is commonly found in baked goods like cakes, cookies, and pastries, as well as in confectionery and snack foods.

In the United States, flavorings like butter emulsion are generally regulated by the FDA as either Generally Recognized As Safe (GRAS) or approved food additives, with their individual components being evaluated for safety. Diacetyl, a compound often used in butter flavorings, has been linked to severe respiratory disease ('popcorn lung') in workers exposed to very high levels in manufacturing environments, but scientific evidence does not show that consuming foods with diacetyl at typical levels causes these health problems. JECFA has evaluated diacetyl and established an acceptable daily intake.
