Abstract: Snacks are foods that are increasingly being provided to dogs. The addition of natural antioxidants in this type of food improves its nutritional composition and brings benefits to animal health. The objective was to evaluate the effects of natural antioxidants (turmeric and marigold) on the physicochemical and technological characteristics and on the shelf life of canine biscuits made with three sources of fat (canola, linseed and olive oil). The parameters analyzed were: antioxidant activity, lipid oxidation, color and texture in biscuits with up to 60 days of storage. The addition of turmeric to the biscuits increased the antioxidant activity and intensified the color of the biscuits, although it did not influence the oxidative stability. The addition of linseed oil contributed to a greater formation of maloaldehyde. Storage reduced the hardness of the biscuits and increased lipid oxidation. It is concluded that the addition of turmeric increases the antioxidant activity, influences the color but does not influence the oxidative stability and texture of dog biscuits.
