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.
HOW IAMS PRESERVES WET FOODS
Wet foods, such as IAMS™ ProActive Health™ with Chicken and Whole Grain Rice Pate, do not require preservatives because they are preserved by packaging. When the ingredients are mixed and ready for cooking, the mixture is packed into cans, trays or pouches and cooked in a retort. Similar in principle to a pressure cooker, the retort sterilizes and preserves the product.
The cans, trays or pouches are then cooled under conditions that assure product sterility and container integrity.
THE SHELF LIFE OF IAMS DOG FOOD PRODUCTS
Thorough shelf-life testing is conducted on all our products. In general, shelf lives for various types of products are:
24 months for wet foods
16 months for dry foods
12 months for biscuits
By using a preservative system in our dry dog food and preservation through packaging in our wet dog food, IAMS makes sure the food your dog eats is well-balanced and nutritionally beneficial.
