Liquid Hickory Smoke

Liquid hickory smoke is a flavoring made from the smoke produced by burning hickory wood. The smoke is condensed and filtered to create a liquid extract that captures the smoky flavor and aroma of the wood.

Manufacturers add liquid hickory smoke to foods to impart a smoky flavor without the need for traditional smoking methods. It is commonly found in barbecue sauces, processed meats like jerky, marinades, snack foods, and some cheese products.

Liquid hickory smoke is generally recognized as safe (GRAS) by the FDA for use as a flavoring agent. Regulatory bodies like JECFA have evaluated it, but did not set a numeric limit (ADI not specified). Some studies have raised concerns about polycyclic aromatic hydrocarbons (PAHs) in smoke flavorings, but manufacturers often use purified versions to minimize these compounds. Research into the long-term health effects of consuming these compounds at typical dietary levels is ongoing.
