TBHQ And Citric Acid Added To Improve Stability

TBHQ (tertiary butylhydroquinone) is a synthetic antioxidant. Citric acid is a natural acid found in citrus fruits, often produced commercially by fermenting sugar. Together, they help prevent oils and fats in foods from going rancid.

TBHQ and citric acid are added to foods containing fats and oils to prevent oxidation, which can cause spoilage and off-flavors. They are commonly found in processed foods like baked goods, fried snacks, cereals, and some processed meats.

TBHQ is approved by the FDA as a food additive. JECFA has evaluated TBHQ and established an acceptable daily intake. Some studies in animals have shown potential health effects at very high doses, but regulatory bodies consider it safe at the levels typically used in food. Citric acid is generally recognized as safe (GRAS) by the FDA and is widely consumed in foods and beverages.
