If you’ve spent any time shopping for dog food or treats lately, you’ve probably seen the term freeze-dried. From complete and balanced meals to toppers and treats, freeze-dried options have become increasingly popular with pet parents looking for convenient ways to add high-quality animal proteins to their dog’s bowl.
But what exactly does freeze-dried mean? And how does a piece of raw meat become something you can store in your pantry?
Here’s a closer look at how freeze-drying works, why we use it, and a few different ways you can incorporate freeze-dried food into your dog’s routine.
What Is Freeze-Drying?
Freeze-drying is a preservation process that removes moisture from food while it is frozen.
Instead of relying on high temperatures to remove water, freeze-drying uses a combination of very low temperatures and reduced pressure. This allows frozen water within the food to transition directly from ice into water vapor through a process called sublimation.
Once most of the moisture has been removed, the finished food is lightweight and shelf-stable while retaining much of the original structure and characteristics of the ingredients.
Freeze-drying isn't unique to pet food. The technology has been used for decades in applications ranging from food preservation to pharmaceuticals and space travel, particularly when reducing moisture and weight while maintaining the characteristics of the original material is important.
Why Use Freeze-Drying for Dog Food?
One of the biggest advantages of freeze-drying is that it allows us to create shelf-stable foods and treats without relying on the same cooking process used to produce traditional kibble.
Because moisture is removed while the food remains at relatively low temperatures, freeze-drying helps preserve the taste, aroma, and nutritional qualities of the ingredients.
It also gives us flexibility in how we formulate different products. Depending on the recipe, freeze-dried products can be made with high levels of meat and organ ingredients and can be used as complete meals, meal toppers, mixers, or treats.
At Muenster, we make our freeze-dried products in our own facility in Denton, Texas, giving us control over the process from formulation through finished product.
How Does the Freeze-Drying Process Work?
While the science behind freeze-drying can get pretty technical, the basic process is surprisingly straightforward.
1. The Food Is Frozen
The prepared ingredients are placed onto trays and loaded into the freeze-dryer. The product is kept frozen so the water contained within the food becomes ice.
2. The Chamber Is Placed Under Vacuum
The freeze-dryer dramatically reduces the pressure inside the chamber. Creating this low-pressure environment is what makes the next step possible.
3. The Trays Gradually Warm
Under carefully controlled conditions, a small amount of heat is introduced.
Because the chamber is under vacuum, the frozen water doesn't melt into liquid as it normally would. Instead, it transitions directly from ice to water vapor.
That process is called sublimation.
4. The Moisture Is Collected
The released water vapor travels to extremely cold condenser plates inside the freeze-dryer, where it freezes again and accumulates as ice.
Over time, this process draws moisture out of the food. A freeze-drying cycle can take many hours depending on the product, recipe, and other processing conditions.
5. The Finished Product Is Packaged
Once the appropriate amount of moisture has been removed, the freeze-drying cycle is complete and the product can be packaged.
The result is a lightweight, shelf-stable food or treat that's convenient to store and easy to serve.
Is Freeze-Dried Dog Food Raw?
Freeze-drying and cooking are two different processes. Freeze-drying primarily removes moisture rather than cooking the food in the way extrusion, baking, or other heat-based processes do.
Because manufacturing methods can vary by brand and product, however, it's important to look at the specific product rather than assuming every freeze-dried food is made exactly the same way.
You should also follow the handling and storage instructions provided on the package.
How Can You Feed Freeze-Dried Dog Food?
One of our favorite things about freeze-dried food is its versatility. Depending on the specific product, there are several ways to add it to your dog's routine.
Feed It as a Complete Meal
A freeze-dried food that is labeled complete and balanced for your dog's appropriate life stage can be fed as their primary diet.
Our Freeze-Dried Complete & Balanced Bites are formulated for everyday feeding, giving you a convenient way to serve freeze-dried nutrition as a complete meal.
Whenever you're changing your dog's primary food, transition gradually to help their digestive system adjust.
Mix It With Kibble
You don't have to feed an entirely freeze-dried diet to incorporate freeze-dried food into your dog's bowl.
Try adding freeze-dried pieces to your dog's regular kibble for additional taste, texture, and variety. Just remember that those additional calories count toward your dog's total daily intake.
Use It as a Meal Topper
Freeze-dried products can also make an easy topper, especially for dogs who could use a little extra excitement at mealtime.
Depending on the product, you can crumble pieces over kibble or serve them whole.
Use Freeze-Dried Treats for Training and Enrichment
Freeze-dried treats are lightweight, easy to store, and often highly appealing to dogs, making them a convenient option for training or enrichment.
You can even turn treat time into a game. Try hiding a few Freeze-Dried Beef Liver Treats around the house and letting your dog use their nose to find them.
How Much Freeze-Dried Food Should You Feed?
One important thing to remember is that removing water makes freeze-dried food much more concentrated by weight than its original fresh ingredients.
That means a serving may look smaller than the amount of kibble or other food you're accustomed to putting in your dog's bowl.
Rather than comparing portions visually, follow the feeding recommendations for the specific product and adjust based on your dog's individual needs.
Age, weight, activity level, metabolism, body condition, and the other foods and treats your dog eats throughout the day can all affect how much food they need.
If you're using freeze-dried food as a topper, mixer, or treat rather than as the primary diet, be mindful of the additional calories you're adding. Your veterinarian can also help you determine an appropriate daily calorie intake for your dog.
Is Freeze-Dried Dog Food Right for Your Dog?
Freeze-dried food can be a convenient way to incorporate high-quality animal proteins into your dog's routine without giving up the convenience of a shelf-stable product.
Whether you use it as a complete meal, mix it with kibble, sprinkle it on top, or reserve it for treat time, the most important thing is choosing a product that fits your dog's nutritional needs and feeding it appropriately.
