TBHQ And Citric Acid Added To Protect Freshness

TBHQ (tert-Butylhydroquinone) is a synthetic antioxidant. Citric acid is a natural acid found in citrus fruits. When used together, they help prevent oils and fats in foods from going rancid, which can cause off-flavors and smells.

TBHQ and citric acid are added to foods containing fats and oils to extend shelf life and maintain quality. They are commonly found in processed foods such as vegetable oils, shortening, baked goods, cereals, potato chips, and other snacks.

TBHQ is approved by the FDA as a food additive. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated TBHQ. Some studies in animals have raised questions about potential health effects at very high doses, but regulatory bodies consider it safe at the low levels typically used in food.
