Hickory

Hickory is a type of tree native to North America. Its wood is commonly used to impart a smoky flavor to foods, particularly meats. This is often achieved through smoking processes or by using hickory smoke flavorings derived from the wood.

Hickory is primarily used as a flavoring agent to give foods a distinct smoky taste. It is frequently found in processed meats, barbecue sauces, seasonings, and snack foods. Manufacturers use it to mimic the flavor of foods cooked over a hickory wood fire.

Hickory itself is not typically regulated as a food additive by the FDA. When used as a flavoring derived from wood smoke, the process and resulting compounds are generally recognized as safe for consumption at typical levels. Regulatory bodies like JECFA and EFSA have evaluated smoke flavorings, but specific evaluations of 'hickory' as a standalone ingredient are not widely documented in their public databases. Concerns about compounds in smoke, such as polycyclic aromatic hydrocarbons (PAHs), have been raised, but these are usually associated with direct burning and charring rather than controlled flavoring processes.
