Light, oxygen and heat are detrimental factors coming across during long storage periods of feedstuff and feed processing that may result in diminished vitamin E activity. Chemically synthesized compounds of α-tocopheryl acetate showing more resistance to oxidation during storage.

Vitamin E 50%, feed grade (all-rac-α-tocopheryl acetate) is a nearly white to slightly yellowish micro-granulate. The usage of silicic acid, precipitated and dried (E 551a) during the state-of-the-art micro-granulation process ensures an excellent adsorption and flowability of our vitamin E preparation.
