ENDOX® - Preserve Feed Quality

With over 50 years of research and experience in the animal feed industry, Kemin has identified some antioxidants are more efficacious in various types of processes and products than others. With this knowledge, Kemin instituted specific blends of antioxidants and chelators (to control free radical formation) to meet the quality demands of specific feeds and feed ingredients.

Complex Process of Oxidation

Oxidation can be defined as the destruction of unsaturated fatty acids in the presence of oxygen.1 This process is initiated by exposure to oxygen, enzymes, metal ions, heat, or light.  During oxidation, oxygen is absorbed and free radicals are produced which accelerate the conversion of unsaturated fatty acids to byproducts such as peroxides and secondary oxidatives. This process can have a major impact not only on quality, but on the performance of livestock and poultry.

An Ideal Antioxidant System

The ideal antioxidant needs to be able to prevent the destruction of unsaturated fatty acids and control the production of free radicals.  In order to accomplish this, an antioxidant system should be used. This system consists of:

  • Synergistic blend of antioxidants to quench free radicals before they can attack unsaturated fatty acids
  • A metal chelator to bind metal ions, which can act as pro-oxidants and form free radicals

Superior Manufacturing

Antioxidant activity is a contact sport. In order to control oxidation, it is essential to ensure a homogenous distribution antioxidant activity in the feed matrix. Conventional antioxidants are often simply dry mixtures containing crystals of the antioxidants and carriers. ENDOX® uses a proprietary manufacturing process to apply active antioxidants to the surface of a dry carrier. This allows nearly every particle to be covered with an active antioxidant mixture and allows for the homogeneous distribution of the antioxidants in the feed or feed ingredient.
