What it is

TBHQ, or tert-Butylhydroquinone, is a synthetic antioxidant. It is made from hydroquinone, which is derived from petroleum.

Why it's used

TBHQ is added to foods to prevent fats and oils from spoiling, which helps maintain freshness. It is often found in high-fat foods like fried snacks, baked goods, and processed meats.

Health notes

TBHQ is permitted for use as a food additive in the United States. The FDA has evaluated TBHQ and it is listed as GRAS (Generally Recognized As Safe) under specific conditions. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated TBHQ. Some studies have raised questions about its effects at very high doses, but regulatory bodies have determined it is safe at the levels typically found in food.

Allergen info
