TBHQ And Calcium Propionate

TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant. It is a white to off-white crystalline powder that is produced through a chemical process.

TBHQ is used to prevent oils and fats in foods from going rancid, extending shelf life. It is often found in processed foods with high fat content, such as fried snacks, baked goods, and processed meats.

TBHQ is permitted for use in the U.S. as an antioxidant by the FDA. It is generally recognized as safe (GRAS) when used within specified limits. Some studies have raised questions about potential health effects at very high doses not typically found in food, but regulatory bodies like JECFA and EFSA have evaluated its safety and established guidelines for its use. Evidence on long-term effects at typical consumption levels is mixed.
