TBHQ Abd Citric Acid Added To Protect Flavor

TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant. It is made from hydroquinone, which is derived from petroleum. Citric acid is a natural acid found in citrus fruits, but it can also be produced industrially through fermentation.

TBHQ is added to foods to prevent oils and fats from going rancid, extending shelf life. Citric acid is used to add a tart flavor, act as a preservative, and enhance the effectiveness of antioxidants like TBHQ. They are often found together in processed foods containing fats and oils, such as baked goods, snack foods, and processed meats.

TBHQ is permitted by the FDA as a food additive to protect flavor and prevent oxidation. The FDA has established limits for its use in food. JECFA has evaluated TBHQ and established an acceptable daily intake. Some studies in animals have raised questions about potential health effects at very high doses, but regulatory bodies like the FDA consider it safe at permitted levels in food. Citric acid is generally recognized as safe (GRAS) by the FDA.
