TBHQ And Citric Acid To Preserve Freshness

TBHQ (tert-Butylhydroquinone) is a synthetic antioxidant. Citric acid is a weak organic acid found naturally in citrus fruits. When used together, they help prevent oils and fats in foods from going rancid, thus preserving freshness and flavor.

TBHQ and citric acid are added to foods containing fats and oils to prevent oxidation and spoilage. This helps extend the shelf life of products like processed snacks, baked goods, and frozen meals, maintaining their quality over time.

TBHQ is approved by the FDA as a food additive and is generally recognized as safe (GRAS) when used within specified limits. Studies in animals have looked at high doses, but at typical dietary levels, it is not associated with adverse health effects. JECFA and EFSA have evaluated TBHQ and established acceptable daily intakes. Some consumer groups have raised concerns, but regulatory bodies consider it safe at permitted levels.
