D-alpha-tocopherylacetate

D-alpha-tocopheryl acetate is a synthetic form of vitamin E, a fat-soluble nutrient. It is made by chemically combining alpha-tocopherol (vitamin E) with acetic acid. This process stabilizes the vitamin, making it less prone to oxidation and easier to use in food production.

Manufacturers add D-alpha-tocopheryl acetate to foods as a source of vitamin E, which acts as an antioxidant. It helps protect fats and oils in food from becoming rancid, extending shelf life. It is commonly found in fortified foods like powdered drinks, nutritional shakes, and energy bars.

D-alpha-tocopheryl acetate is generally recognized as safe (GRAS) by the FDA for use as a nutrient and antioxidant. Vitamin E is essential for health, acting as an antioxidant that protects cells from damage. Regulatory bodies like JECFA and EFSA have evaluated vitamin E and its derivatives, establishing acceptable intake levels. High doses of vitamin E supplements can interfere with blood clotting, but this is not typically a concern with dietary intake from fortified foods.
