In pet foods, preservatives slow down or prevent the breakdown, or oxidation, of the product, thereby helping it maintain its nutritional value longer. IAMS™ uses a preservative system in its dry dog food to make sure your dog receives the freshest product possible, from shelf to bowl.
How IAMS Preserves Dry Dog Food
Active dogs thrive on diets high in fat. To preserve a high-fat dry kibble diet, however, is a challenge. The IAMS research team met that challenge with an effective preservative system used in all our dry dog food products, such as IAMS™ ProActive Health™ Adult MiniChunks.
The preservative system features a special blend of mixed tocopherols. Tocopherols are antioxidants extracted from vegetable oils. There are four major types of tocopherols. Vitamin E, also known as alpha-tocopherol, is commonly used in dog foods, though a specific mixture of the different tocopherols protects against rancidity.
Our preservative system slows the rate of oxidation and allows for an extended shelf life.
