TBHQ And Citric Acid Added To Help Protect Flavor

TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant. Citric acid is a naturally occurring weak acid found in citrus fruits. When used together in food, they help prevent oils and fats from going rancid, which can cause an off-flavor.

TBHQ and citric acid are added to foods to protect flavor and prevent spoilage by acting as antioxidants. They are often found in foods containing fats and oils, such as vegetable shortenings, baked goods, fried snacks, and some processed meats.

TBHQ is approved by the FDA as a food additive and is generally recognized as safe (GRAS) when used within specified limits. Both the FDA and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have evaluated TBHQ. Some studies in animals have raised questions about potential health effects at very high doses, but regulatory bodies have concluded it is safe at levels typically found in food. Citric acid is also widely used and considered safe.
