BHT With Citric Acid Added To Help Protect Flavor

BHT, or butylated hydroxytoluene, is a synthetic antioxidant. It is created through a chemical process involving p-cresol and isobutylene. BHT is structurally similar to vitamin E and functions as an antioxidant.

Manufacturers add BHT to foods to prevent fats and oils from becoming rancid, which helps protect flavor and extend shelf life. It is commonly found in products with fat content, such as pizza, baked goods, and processed meats.

In the U.S., BHT is generally recognized as safe (GRAS) by the FDA when used as a food additive. It is also approved for use in other countries. Some studies have explored its potential antioxidant benefits and its role in cellular health, but research is ongoing and evidence is mixed. Regulatory bodies like JECFA and EFSA have evaluated BHT, and it has been the subject of some public discussion regarding its safety, though scientific reviews have generally supported its use at typical levels.
