Tocopherol, commonly known as Vitamin E, is frequently used as a natural preservative in pet foods. It helps to extend the shelf life of products by preventing the oxidation of fats, which can lead to rancidity and loss of nutritional value. Tocopherol is preferred over synthetic preservatives such as BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) due to its natural origin and additional health benefits. As an antioxidant, tocopherol not only preserves the freshness of pet food but also supports the immune system, skin, and coat health of pets. Its inclusion in pet food aligns with the demand for more natural and wholesome ingredients, especially in premium brands.
