The most popular freeze-dried dog foods are made using a modern moisture removal technique. Indeed, freeze-drying keeps the nutritional value of foods unchanged and increases its shelf life.
Obviously, freeze-dried pet foods are no-brainers for any responsible pet parents out there striving for better nutrition for their dogs. Over the last decades, the pet food industry and its giants have disappointed the general audience with hundreds of recalls. So, it was a matter of time until new brands with more ethical goals joined the party. However, freeze-dried dog foods are on the higher bracket in terms of pricing.
What is freeze-dried dog food?
Freeze-dried dog food is freshly cooked dog food that has had its moisture content completely removed, rendering it dry and long-lasting. This process works because the microorganisms that rot our food need water to survive. Thus by removing all the water from pet food through this process, it essentially makes the food immune to rotting and gives it longer shelf life. Meat, vegetables, poultry are amongst common ingredients that get freeze-dried.
The food, after freeze-drying, is carefully packaged in temperature-controlled packaging material, which makes it last for years also sometimes. This type of pet food is an excellent standby product for when you cannot prepare fresh food for your dog. Simply replenishing the food product with some freshwater, can turn the food back to normal and edible. The best part about freeze-drying is that the nutrients in the food remain intact, making the meal highly nutritious and sufficiently nourishing for your dog.
How is freeze-dried food prepared?
Freeze-drying is made using a three-step process:
- Cooking – fresh dog food including chicken, lamb, turkey, duck, beef and even veggies like sweet potatoes, carrots are cooked
- Drying – foods are placed on shelves inside the freeze-drying chambers and the temperature is slowly lowered, making it extremely icy within
- Packaging – foods are packaged into special moisture-resistant bags allowing the food to stay intact and fresh for around 12 months
The second step, the freeze-drying process, isolates the molecules in the food. Then, it is exposed to slight heat and a strong vacuum. This causes the water content of the food to evaporate and sucked out of the chamber. The food inside is left dry, whilst leaving its nutritional value unchanged.
Is freeze-dried food considered raw?
Freeze-dried food products, that have not been cooked before the process, are indeed raw.
Contrary to popular belief, dog food that is processed in some way does not mean it has been cooked. Food is cooked when heat is applied to it. In this process, no heat is being applied – only the moisture content being reduced to nil.
In fact, because this type of food is to be eaten after hydrating it, the product returns to the same form as it was before the process. Which makes it raw, even after restoring moisture to it.
Freeze-dried vs Dehydrated dog food
This argument is fairly common owing to the final byproduct that we get using both these processes.
But are they really same?
Dehydrated foods use heat application to dry the food out while freeze drying is done by letting the water vaporize and then slowly sucking it out. It is a slightly more complex process.
Both methods are used in order to make the food last longer and make it convenient to transport. Both the processes involve removal of moisture, making them lightweight also. However, research suggests that freeze-drying, which is a relatively new process as compared to dehydrating, is a much healthier and safer way to do this.
There are plenty of reasons that put freeze-drying as a healthier process than dehydration.
Freeze-drying removes up to 99% moisture. Dehydrating removes about 90% of moisture. This could lessen the shelf life of a dehydrated product as this is directly linked to how much water is in the end product.
Freeze-dried foods rehydrate faster than dehydrated products. Adding water to both will restore them to their original form, but freeze-dried products get there faster.
Nutrition and Flavor
Freeze-dried products retain their nutritional value to a great extent, while dehydrated products lose some of their nutrition owing to high heat exposure. Flavour and aroma retention is higher in freeze-dried products. Dehydrated products tend to lose their luster and taste slightly flat.
Dehydrated products also tend to become leathery and dense while freeze-dried products bounce back to their original form, shape, and texture almost instantly. Overall, both textures are still very much above anything else available on the commercial market – kibble or even canned foods.
How to store freeze-dried pet food?
At large, freeze-dried pet food is stored in mylar pouches – a material derived from polyester resin. These pouches block sunlight to a great extent, preventing heat from entering the package and affecting the food. These pouches also lock moisture outside, thus keeping the food product safe and usable for many years. If your pet food is stored in mylar pouches, you can leave it outside at room temperature also in a dry place away from direct harsh sunlight.
Another popular method of storing freeze-dried pet foods is in cans. Not your normal cans, but nitrogen packed, airtight ones that work by vacuuming out all the oxygen from inside and flushing it clean with nitrogen. In the absence of oxygen, microorganisms cannot survive either, making the food immune to rotting or degrading.
How long can freeze-dried food be stored for?
Unopened cans and pouches of freeze-dried pet food can have a shelf life of over 30 years. But once opened, they start degrading. How fast they rot depends upon a lot of factors like the quality of the food at the time of it being exposed to oxygen and also the quality of air, in which is being opened.
The more the pollution, the more microorganisms in the air and faster the degradation. If you wish to open the packet but only use half of it, store them well. Putting them into Ziploc bags works well. To go a step further, you could also use a straw to suck out all the air and then seal it.
What are the most popular freeze-dried dog food brands?
The market for these products is widening owing to concerned pet-parents who are a lot more aware of their pet’s needs. They understand that their dogs need optimum nourishment.

Enter the world of freeze-dried foods: they are raw, hygienic, have longer shelf lives, easier to store and provide way more nutrition than your average commercial dog food!
