Potassium Sorbate And Citric Acid And TBHQ

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring compound found in some plants. Citric acid is a weak organic acid found naturally in citrus fruits. TBHQ (tert-butylhydroquinone) is a synthetic antioxidant.

This combination is used as a preservative system in baked goods and other processed foods. Potassium sorbate and citric acid work together to inhibit the growth of mold and yeast, while TBHQ prevents fats and oils from becoming rancid, extending shelf life.

Potassium sorbate and citric acid are generally recognized as safe (GRAS) by the FDA. TBHQ is also FDA-approved as a food additive. These ingredients have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some studies have explored potential effects of high doses of TBHQ, though evidence is mixed and not conclusive at levels found in food.
