Freshness Preserved By TBHQ

TBHQ, or tert-Butylhydroquinone, is a synthetic antioxidant. It is made from hydroquinone and isobutylene. It is a white to off-white crystalline powder.

TBHQ is added to foods to prevent oils and fats from spoiling, which extends shelf life. It is commonly found in products with high fat content, such as fried snacks, baked goods, and processed meats.

TBHQ is approved by the FDA as a food additive. It is also permitted for use in the European Union and other regions. JECFA has evaluated TBHQ and established an acceptable daily intake. Some studies in animals have shown effects at very high doses, but these are not considered relevant to typical human consumption levels. Evidence does not suggest adverse health effects at the levels typically consumed.
