Tert-Butylhydroquinone, typically referred to as TBHQ, is a crystalline antioxidant. TBHQ is used in food because it blocks the presence of oxidation in fats. Oxidation weakens flavor, alters the coloring in food, and can also result in fats turning rancid. TBHQ is thus used to prevent those effects of oxidation, increase the shelf life and reduce spoilage. You will find TBHQ in a variety of processed foods, including pasta, cereal, crackers, microwave popcorn, chicken nuggets and other fried foods. A similar additive is butylated hydroxyanisol, which is often used in combination with TBHQ. TBHQ is added to the soybean oil in White Castle onion rings recipe.
