Petfood manufacturers need the fats in their feed ingredients to be in perfect condition! Rancidity can cause numerous problems, not least of which is the creation of volatile products of fat (or lipid) oxidation which have a significant negative impact on palatability. In addition, some products of secondary stages of oxidation can degrade many fatty acids, amino acids and vitamins, as well as being carcinogenic themselves!

All feed lipids will naturally decay by a process of auto-oxidative rancidity, usually initiated or accelerated by catalysts such as heat, light, certain metal ions and humidity. The critical role of an antioxidant is to act ‘sacrificially’ to delay and/or greatly reduce the speed of this oxidative decay, even in the presence of catalytic factors.

From a commercial point of view, it is imperative to ensure that adequate antioxidant protection is provided, in both finished pet food and feed ingredients. Often it will be assumed that a feed ingredient supplier will have used an appropriate antioxidant to ensure long and stable shelf-life of their ingredient, but more often that you might think, this is not true, which threatens the integrity of the finished food still further. An ingredient that has already started down the irreversible path of oxidation, once mixed with other ingredients, will actually make the whole mixture oxidise more quickly! So, it is critical that ingredients contain appropriate antioxidant protection as well as finished foods.

The choice of antioxidant is an important one. A key consideration is whether to use a synthetic antioxidant, which are coming under ever-more scrutiny and legal restriction, or a natural antioxidant which benefit from a distinct ‘clean label’ position.

OxiSafe DF-P is specifically designed for a broad range of pet foods and feed ingredients, both dry and wet;

• A synergistic blend of natural antioxidants, giving a broad-spectrum of antioxidant action.
• Each antioxidant works by interacting at a different point in the ‘cascade’ of harmful oxidation reactions. A variety of modes-of-action gives the best protection across a variety of feed preservation scenarios. The antioxidants in OxiSafe DF-P act by either by neutralising the production of free radicals, ‘chelating’ certain metal ions or acting as oxygen receptors.
• Our mixed tocopherols are ‘Delta-rich’. Studies have shown that the ‘delta tocopherol’ isomer has significantly the best antioxidant activity in feed fats, compared to other tocopherols.
OxiSafe DF-P is also high in Gamma-tocopherol, which has the next strongest antioxidant action after Delta-tocopherol. Alpha-tocopherol, whilst having the best ‘Vitamin E’ activity in vivo, actually has the weakest antioxidant activity for feed fats In vitro.

OxiSafe DF-P is in convenient powder form, in 25kg pack
