Antioxidant TBHQ

TBHQ, or tert-butylhydroquinone, is an antioxidant and food preservative synthesized for use in processed foods, aiming to extend their shelf life and inhibit rancidity.

TBHQ’s primary role in food is as an antioxidant. It counteracts oxidation of fats and oils in food, aiding in preserving their quality and stability.

Concerns about TBHQ’s potential health risks stem from issues related to chronic exposure or high doses. These risks include its potential effects on cancer cells and the body’s natural antioxidant defenses.

TBHQ is prevalent in various processed foods, such as snacks, baked goods, and fast food, where it helps maintain freshness and quality during storage and transportation.

Regulatory bodies such as the FDA and EFSA have provided guidelines and safety limits for TBHQ as a food additive, ensuring its use within defined levels.

TBHQ can impact the body’s antioxidant response system by interacting with the transcription factor Nrf2, which plays a vital role in cellular protection against oxidative stress.

Excessive use of TBHQ has sparked concerns due to its potential impact on food allergies and the effects of its metabolites on overall health with prolonged exposure.

Research indicates that while TBHQ is beneficial as a food preservative, excessive or prolonged exposure at high levels could present risks, including effects on cellular function and cancer cells.

TBHQ’s primary use in the food industry is as a synthetic antioxidant. It effectively inhibits the oxidation of fats and oils in food products, thereby extending their shelf life and preserving sensory characteristics.

Concerns about TBHQ often relate to its use with other food preservatives like BHA. The potential cumulative effects of these compounds, especially with prolonged or excessive use, may impact human health and well-being.
