Where oxidation costs money

Oxidation is a slow, invisible loss. Rancid fat delivers less energy, oxidized vitamins and pigments no longer perform, and the peroxides formed on the way impose an oxidative load on the animal. Santoquin is the ethoxyquin-based range, formatted for each point in the chain where oxidation starts: a highly concentrated liquid for fats and oils, a granulate for premixes and finished feed, and blends where synergy allows a lower total inclusion.

Lipid oxidation begins as soon as fat is exposed to oxygen, heat, light and metal ions, and it accelerates through processing and storage. The measurable consequences are lower metabolizable energy from the fat fraction, loss of vitamins A, D, E and of carotenoid pigments, reduced palatability, and the formation of peroxides and secondary oxidation products that the animal then has to handle. Rendered products, fish meal, and high-oil ingredients present the highest risk.

How they work

0 Radical scavenging.

Phenolic antioxidants donate a hydrogen atom to lipid peroxyl radicals, interrupting the chain reaction that propagates rancidity.

0 Synergy between actives.

Combining antioxidants with different partition behavior and regeneration chemistry gives greater protection per unit than any single molecule, which is the basis of the Max and Q4T blends.

0 Concentration and carrier.

The same active is delivered as a concentrated liquid for dosing into fat and oil streams, and on a granular or powdered carrier for dry dosing into premix and complete feed.

0 Protection of the animal.

By slowing peroxide formation in the feed, antioxidants preserve the nutritional value of the feed and reduce the oxidative load the animal has to manage.

Technical notes

Format and substrate.

Liquids are dosed into fat and oil streams at the rendering or crushing plant. Granular and dry formats are dosed at blending or at the mixer. Matching the format to the substrate matters more than the nominal concentration of the active.

Verification.

Antioxidant performance is verified on the substrate, by peroxide value or accelerated oxidation testing under the storage conditions the ingredient will actually see.

Feed Quality

Where it fits

Apply at the earliest point in the chain where oxidation can start. For rendered fats and fish meal that is the rendering or crushing plant, and the answer is Santoquin Liquid or Q4T. For premixes and complete feed, dosing happens at blending or at the mixer, and the answer is Mixture 6 or Max.
