Additional Ingredients in Dog Food: Understanding Animal Digest, Garlic Oil, and Coloring Agents

Beyond the primary nutrients, pet foods often contain ingredients aimed at enhancing palatability, aroma, and appearance. In the example ingredient list, the remaining ingredients—animal digest, garlic oil, and coloring agents (Red 40 and Yellow 5)—each serve specific purposes in making the food more appealing. Here, we break down these ingredients and address their roles in pet food.

What is animal digest, and why is it used in dog food?

Animal digest is an ingredient that enhances the flavor and aroma of pet food, making it more appetizing to pets. According to AAFCO, animal digest is created through enzymatic or chemical hydrolysis of animal tissues, typically using ingredients like liver or washed chicken organs due to their high enzymatic activity. This process breaks down proteins and fats, releasing free amino acids and fatty acids that pets find highly palatable.

How It’s Used: The digest is heated to halt the enzymatic activity and ensure it is sterile. It can be applied as a liquid or spray-dried powder to coat the exterior of kibble, increasing its flavor appeal. Animal digest is comparable to “giblet gravy” in that it enhances taste and aroma, enticing pets to eat.

Why is garlic oil included in pet food, and is it safe?

Garlic oil is added in minimal amounts to enhance flavor and aroma. Although garlic in large amounts can be harmful to dogs, the very low level used in pet food formulations is carefully controlled to be safe and effective. In fact, the amount of garlic oil is so small that it’s typically included at a lower concentration than many trace nutrients, such as copper proteinate.

Role in Pet Food: The garlic oil acts as a palatant—an ingredient that boosts the flavor profile—making the food more enjoyable for pets. Its inclusion, along with fat and animal digest, enhances the overall palatability of the product.

What purpose do coloring agents serve in dog food?

Coloring agents, such as Red 40 and Yellow 5, are used in pet food primarily for visual appeal to pet owners. These dyes are not nutrients and do not impact the pet’s health directly, but they give the food a color that may be more appealing to the buyer. Pet owners often prefer food that looks attractive, as it influences their perception of the product’s quality.

Types of Coloring

Safety: All colors approved for pet food use are evaluated for safety. Although some pet owners prefer foods without artificial colors, others appreciate the added visual appeal, and manufacturers use the lowest effective level of dye to achieve the desired color.
