Pet food

Antioxidants

Manufacturers and brand owners are highly aware of pet food’s susceptibility towards oxidation. The risks associated with the formation of free radicals, the rancidity development and subsequent deterioration of the product quality, the negative impact on palatability, as well as the exposure on social media platforms, remain a major concern.

 

Controlling oxidation is top priority. CFS’s natural NaSure® Antioxidants  or synthetic Xtendra® Antioxidants address the needs for long-term stabilization of regular as well as premium types of pet food. Obviously, better pet food diets with polyunsaturated fatty acids require more potent solutions based on combinatory antioxidant systems.

It is essential to protect the kibble pre- and post-extrusion (Fig. 1). Addition to the dry base protects against free radical formation and oxidation caused by the friction, shear and heat of the extrusion process. After the extrusion, depending on the oxidative challenge, a specific antioxidant protection system is added to the coating oil.

Through dialogue CFS can help to identify the most optimal protection of the pet food system.

Development of primary oxidation products (hydroperoxides) and secondary oxidation products (in this case hexanal) in extruded pet treats protected with a natural antioxidant combination of 500 ppm dry NaSure® 580 (treatment of the dry base/kibble matrix) and 1000 ppm liquid NaSure® 551 (treatment of coating oil based on rapeseed oil).
