Tomato Pomace as a Pet Food Ingredient?

When looking at the ingredient of a dog food formula, you may have noticed Tomato Pomace or Dried Tomato Pomace as one of the minor ingredients. 

But what exactly is Tomato Pomace? Why is it used in so many dog foods recipes and is it a nutritious ingredient that can provide a notable benefit to your dog? Let’s break down these critical questions one at a time.

Sliced Tomato That Could Be Made Into Tomato Pomace

What is Tomato Pomace?

The skin, pulp and crushed up seeds of raw tomatoes are the core ingredients of that makeup Tomato Pomace. It is created as a by-product of the juicing process that creates ketchup, tomato juice, tomato soup and many other tomato-based products that we see and purchase on our grocery shelves. 

Many years ago, this particular by-product may have gone to waste as there was no valuable use for it. Today, however, Tomato Pomace is sold to dog food manufacturers who use it as an ingredient in their dog food formulas.

Why is Tomato Pomace in Dog Food?

There are a few reasons why Tomato Pomace is present in dog food. One of the most notable of these reasons is that it contains a significant amount of soluble fiber. Dogs need soluble fiber for the same reason that humans do – healthy digestion and regular bowel movements. This soluble fiber attracts water and slows the overall speed of digestion. This reduced rate of digestion then allows for more minerals, vitamins, and nutrients to be absorbed, as the food sits in the stomach for a more elongated period.

Therefore soluble fiber is essential for healthy and regular bowel movements. Soluble fiber can also be important for another reason. It can help lower cholesterol and keep blood sugar levels stable which can particularly help dogs suffering from diabetes. The importance and the critical role of fiber in the diets of dogs is one of the reasons that analysis of dog food must contain the minimum amount of fiber present.

Is Tomato Pomace Nutritious?

The nutrition of Tomato Pomace is perhaps its most debatable feature and very much depends on the quality of the Tomatoes that the Tomato Pomace is derived from. High-quality tomatoes are likely to contain high amounts of antioxidants and other vitamins such as Vitamin C, Vitamin K1, and Potassium.

However, lower quality tomatoes are likely to provide a minimal amount of these beneficial antioxidants and vitamins. Therefore, without knowing the exact quality or source of the tomatoes used to produce the Tomato Pomace used in dog food formulas, it is difficult to say whether it will add any significant nutritional value past its high levels of soluble fiber.

What is the Difference Between Tomato Pomace and Dried Tomato Pomace?

Tomato Pomace is naturally high in water. This is unsurprising as we just discussed the large portion of soluble fiber that it contains. As a consequence, this soluble fiber will naturally retain water unless it is dried out. Drying Tomato Pomace removes the majority of this water. However, this drying process does not reduce the ability of Tomato Pomace to act as an excellent source of soluble fiber.

What most people do not realize is that dry dog food or kibble is cooked during the manufacturing process. This cooking process removes the vast majority of moisture from the all the ingredients used in the formula. This cooking process is very similar to the drying process that Dried Tomato Pomace would undergo. Therefore none-dried Tomato Pomace will end up being in a very similar state to dried Tomato Pomace by the time it reaches your dog’s bowl.

A similar comparison could be the use of meat meal vs fresh meat. Both ingredients can both provide the same nutrition, but the meat meal has already had its moisture removed and therefore its portion will not shrink during the cooking process.

Which Dog Foods Contain Tomato Pomace?

Premium dog food brands such as Taste of the Wild, Weruva, Fromm, Nature’s Variety Instinct, and Canidae, among others, use Tomato Pomace as an ingredient in some of their recipes.

Some of these brands advertise the logic behind its inclusion, such as Taste of the Wild. They state that Tomato Pomace is included in their formulas as it is an excellent source of Soluble Fiber and Antioxidants, which mimics what we just discussed above.

Below are two dog food formulas that we rate highly and that contain a small quantity of Tomato Pomace. Be sure to check out the full reviews of each formula for more details.

What Dog Food’s Don’t Contain Tomato Pomace?

However, not all dog food brand use Tomato Pomace as an ingredient. While we don’t know the exact reasoning why these brands choose not to include Tomato Pomace we can make an educated guess. Some premium dog food producers include other sources of soluble fiber and antioxidants in their formulas such as fruits or vegetables like berries and Pumpkin.

Some examples of high-quality dog food brands that don’t use Tomato Pomace include Orijen, Acana, Zignature and Earthborn Holistic. Here are two dog food formulas by these brands that we rate very highly due to the quality of their ingredients and the nutrition they can provide.

Should I be Concerned about High Levels of Pesticides in Tomato Pomace?

It is without question that Tomatoes contain high levels of pesticides. Pesticides are widely used in Tomato production across the USA, Mexico, and Canada. However, there are two reasons that you should not be overly concerned about this heavy use of pesticides.

Firstly the tomatoes used for Tomato Pomace, are the same tomatoes that we eat on a daily basis in foods such as Pizza, Pasta, Ketchup, and Tomato Juice. Therefore if you aren’t concerned about eating these yourself, then it would be hypocritical and odd to be so overly worried on behalf of your dog.

Secondly the quantities of Tomato Pomace present in most dog food formulas is quite low. So low in fact that your dog would have to eat a considerable amount of their food to consume any significant quantity of Tomato Pomace. While it is true that dogs, especially toy breeds, are much smaller than humans, even the proportion of Tomato Pomace relative to the dog’s size is not significant.

However, if you are very concerned about your and your dog’s consumption of pesticides or the general use of pesticides in the modern farming, you may want to go with a dog food formula that contains ingredients that need minimal pesticides to grow effectively.

Tomato Pomace – The Verdict

Tomato Pomace is not something you need to feed your dog actively and therefore you should not get worked up or fret if it is absent from your dog’s favorite formula. While it does have some benefits in antioxidants and soluble fiber, both of these can be provided both other ingredients such as Pumpkin or fresh fruit. These could be given to your dog from within a formula that contains them or as a tasty treat.

If you are worried that that Tomato Pomace could be dangerous, rest assured that in small quantities, it is likely to have no serious adverse effects on your dog’s diet or overall health. The only reason to avoid Tomato Pomace is if it is used in overly high quantities, as it will not provide the protein and fat that your dog desperately needs.
