Freeze-drying avoids high temperatures that can destroy heat-sensitive vitamins, minerals and enzymes in other drying methods. This means freeze-dried foods retain up to 90% of their nutrients compared to around 10-40% in air-dried foods.
The lack of moisture makes freeze-dried foods very shelf-stable and portable. Owners can easily take food while traveling or during emergencies without worry of spoilage.
Since water is removed at a low temperature under vacuum pressure, freeze-drying preserves the natural flavors, aromas, colors and textures of ingredients close to their raw state.
Freeze-dried kibbles are about 20% of the weight and density of canned foods, making them more economical to ship and store. Owners save space both in their pantries and when traveling.
Many pets tolerate freeze-dried foods better than kibbles due to the low-impact drying process. They are also a good transition food when switching diets.
Adding small amounts of water allows owners to portion food and hydrate as needed versus measuring and mixing wet foods.
