Natural and Synthetic Antioxidants for Petfood Stabilization

Kemin’s stability assurance program includes natural* and synthetic antioxidants to control oxidation during all phases of the petfood manufacturing and rendering processes. One of the key features of this program is our integrated approach to freshness protection which ensures that the nutrition and palatability of the petfood is maintained throughout its shelf-life.

Kemin understands that your quality assurance program must address the entire manufacturing process, from raw material quality to finished product stability. A successful quality assurance program requires the right natural or synthetic antioxidants, and the technical support needed to ensure that your objectives are met.
