With Citric Acid And TBHQ

TBHQ, or tertiary butylhydroquinone, is a synthetic antioxidant. It is made from hydroquinone, which is derived from petroleum. TBHQ is added to foods to help prevent fats and oils from spoiling.

TBHQ is used as an antioxidant to extend the shelf life of foods containing fats and oils. It prevents oxidation, which can cause rancidity and off-flavors. It is commonly found in fried and baked goods, processed meats, and snack foods.

TBHQ is permitted by the FDA as a food additive. It is also approved for use in many other countries. Studies in animals have shown that TBHQ can cause some adverse effects at very high doses, but these are not expected at typical human consumption levels. JECFA and EFSA have evaluated TBHQ and established acceptable daily intakes. Some consumer groups have raised concerns about its use, but regulatory bodies consider it safe at permitted levels.
