Tbho And Citric Acid

TBHQ, or tertiary butylhydroquinone, is a synthetic antioxidant. It is made from the chemical compound hydroquinone. TBHQ is often used in combination with other antioxidants like citric acid to improve its effectiveness.

Manufacturers add TBHQ to foods to prevent fats and oils from spoiling, which helps extend shelf life. It is commonly found in processed foods that contain fats, such as fried snacks, baked goods, and processed meats. Citric acid is often added to boost TBHQ's antioxidant power.

TBHQ is an FDA-approved food additive. Regulatory bodies like JECFA have evaluated TBHQ. While generally recognized as safe at low levels, some studies have raised questions about its long-term effects at very high doses, though evidence is mixed. It is not considered a major health concern by most regulatory agencies when used as permitted.
