Freeze-dried Pet Food
All pet owners want the best for their family friends, and rising affluence in many parts of the world has fueled the popularity of freeze-dried food for dogs and cats as a premium product. This has been particularly apparent for raw food which is increasingly seen as a healthier alternative to cooked products, retaining its natural nutrition, with lower salt and without additives.
Dried pet food has enjoyed great popularity for many years, however, freeze drying is increasingly seen as a viable option for the premium market. Freeze drying removes almost all the moisture from the product under extreme vacuum conditions (down to as low as 3-5%). This significantly increases the shelf life and allows drying at a very low temperature when compared with other dried food allowing manufacturers to create new products that can be stored unopened, at room temperature, for years, without spoiling. As the product is exposed only to low temperatures, freeze drying retains more of the nutritional characteristics of the food, for a healthier product.
Freeze-dried raw pet food
Raw meat pet food (Biologically Appropriate Raw Food (BARF)) is also becoming popular. Users report many benefits from feeding their pets raw food including: improved digestion, better dental health, easier weight control, shinier coat, reduced allergies, stronger immune system and fewer behavioral issues.
Although many accept the benefits of raw feeding, the inconvenience of handling and storing raw food can put some pet owners off. Freeze-drying the food, however, provides a fast and simple alternative. The drying process does not cook or heat treat the food, so it is still raw. The product can be reconstituted simply by adding water. This makes the food much easier to handle both for retailers and consumers and is particularly useful for owners who travel with their pets. What’s more, most pets enjoy the taste of freeze-dried raw food, even those who are fussy eaters.
How it works
Have a look at the video, which explains the freeze drying process in a bit more detail.
Types of freeze-dried pet food
A wide range of dog and cat food and treats can be freeze dried. These include: raw chicken, beef, turkey, etc. (95% meat, natural or minced and formed); cooked meat; kibble; snacks – such as biscuits and mixers; and special treats including protein bars. Kibble is usually 5-15% meat with vegetables, cereals, grain and relevant vitamins and minerals.

From fossil fuels to future-ready: The rise of heat pumps
While the initial interest in heat pumps was to save on operating costs, reducing emissions is now the main driver for the technology. Learn more about how GEA is spearheading efforts to increase energy efficiency and reduce CO2 emissions through hidden champion heat pump technology for industrial and district heating sectors.
A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
