D-alpha-tocopherol acetate is the main raw material of various ve health food, which can be used as the intermediate for the synthesis of water-soluble vitamin E. Although the antioxidant activity of free VE is significantly higher than that of VE ester derivatives, because ve esters are easily hydrolyzed to free VE by lipase, the ve performance of food or health care products added with ve ester is not damaged.
