Corn Oil With TBHQ And Citric Acid

Corn oil is a vegetable oil extracted from the germ of corn kernels. It is a common cooking oil used for frying, baking, and in salad dressings. TBHQ (tertiary butylhydroquinone) and citric acid are added to help preserve the oil and prevent it from going rancid.

TBHQ and citric acid are added to corn oil to act as antioxidants and preservatives, extending its shelf life and preventing spoilage. This combination is often found in processed foods like snack crackers, baked goods, and prepared meals where maintaining oil freshness is important.

Corn oil is generally recognized as safe (GRAS) by the FDA. TBHQ is an FDA-approved antioxidant preservative, and citric acid is also GRAS. Studies on TBHQ have shown it can be an irritant in high doses, but it is considered safe at levels typically used in food. JECFA (Joint FAO/WHO Expert Committee on Food Additives) has evaluated TBHQ and established an acceptable daily intake. Evidence on the health effects of TBHQ at typical consumption levels is mixed, with some studies suggesting potential concerns at very high doses not usually encountered in food.
