Usage And Synthesis

Chemical Properties

light yellow to  brownish red liquid, clear, viscous oil. It has a mild, characteristic odour and taste, and its biological avtivity is three times higher than synthetic VE.

Usage

vitamin E, antioxidant

α-Tocopherol is the most bioactive of the naturally occurring forms of Vitamin E. Richest sources are green vegetables, grains, and oils, particularly palm, safflower and sunflower oils.
