Tbho & Citric Acid

TBHQ, or tertiary butylhydroquinone, is a synthetic antioxidant. It is a white or reddish-brown crystalline powder. TBHQ is produced through a chemical reaction involving hydroquinone and isobutylene.

Manufacturers add TBHQ to foods to prevent oils and fats from spoiling, which extends shelf life. It is often found in products containing fats and oils, such as baked goods, cereals, and processed snacks.

TBHQ is an FDA-approved food additive. Studies in animals have looked at its effects, but the FDA has not set a numeric acceptable daily intake (ADI). The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has also evaluated TBHQ. Some research has raised questions about TBHQ's effects at very high doses, but regulatory bodies consider it safe at levels typically found in food.
