What it is
Butylated hydroxytoluene (BHT) is a synthetic antioxidant. It is produced through a chemical process involving p-cresol and isobutylene. BHT is a waxy, white solid.
Why it's used
BHT is added to foods to prevent fats and oils from becoming rancid, which helps extend shelf life. It is commonly found in cereals, crackers, and other processed foods that contain fats.
Health notes
In the US, BHT is generally recognized as safe (GRAS) by the FDA for use as a food additive. Regulatory bodies like JECFA and EFSA have evaluated BHT. Some studies have raised questions about its long-term effects, but research results are mixed, and evidence at typical consumption levels is not conclusive.
Allergen info
BHT is a synthetic chemical and is not derived from any of the nine major allergens. It does not contain gluten.
