Tocopherols And Citric Acid

Tocopherols are forms of Vitamin E, a fat-soluble nutrient found naturally in vegetable oils, nuts, seeds, and leafy green vegetables. Citric acid is a weak organic acid found naturally in citrus fruits. They are often added to foods together as antioxidants.

Tocopherols and citric acid are often used together as a combination antioxidant system. Tocopherols protect fats and oils from becoming rancid, while citric acid helps to stabilize the tocopherols and enhance their antioxidant activity. This combination is frequently added to fats, oils, and foods containing them, such as nut butters and processed fish, to extend shelf life.

Tocopherols are a form of Vitamin E and are generally recognized as safe (GRAS) by the FDA when used as nutrients or antioxidants. Citric acid is also GRAS by the FDA. Both are common food ingredients and are considered safe at typical levels of consumption. JECFA and EFSA have evaluated these substances. No significant health concerns are associated with their consumption at levels found in food.
