Preservative And Natural Hardwood Smoke

Natural hardwood smoke is created by burning wood, typically hardwoods like oak, hickory, or alder, without oxygen. This process produces smoke compounds that can be captured and condensed into a liquid form. This liquid smoke is then used as a flavoring agent.

Liquid smoke is added to foods to impart a smoky flavor without the need for traditional smoking methods. It is commonly used in processed meats, fish, sauces, snacks, and seasonings. It provides a consistent smoky taste and aroma.

Liquid smoke is generally recognized as safe (GRAS) by the FDA for use as a flavoring agent. It is made from compounds found in wood smoke, some of which have raised health questions in high concentrations or when produced by uncontrolled burning. However, the FDA considers the liquid smoke used in food to be safe. JECFA has evaluated smoke flavorings and established acceptable daily intakes for certain compounds, but specific evaluations for the complex mixture of liquid smoke are ongoing. Some studies have explored potential health effects, but typical consumption levels are not associated with adverse outcomes.
