We gently freeze-dry our products to ensure the healthiest pet food and treats available. Freeze-drying helps to lock in freshness and intensify flavors while preventing food from from shrinking or becoming tough as with other processes. For these reasons, and due to the higher nutrient content, it is preferred to other methods of pet food production.
What Is Freeze-Drying?
Freeze-drying is a long, slow process, taking about 24-48 hours from start to finish. This process involves placing the food in a vacuum chamber at sub-zero temperatures to gently extract moisture without the loss of nutrients that happens when food is cooked, baked, or extruded. Since only water is removed, the food retains the characteristics and natural nutrition of fresh, raw food.
How It Works:
- First, food and treats are flash-frozen.
- Next, they are placed on trays and put into a vacuum chamber at sub-zero temperatures (usually ranging from -30 to -50 degrees Fahrenheit.
- In a process called sublimation, low, radiant heat is applied to the trays, which slowly pulls out moisture without cooking to retain nutrients.
- Coils or cold plates act as magnets to attract the water vapor and turn it into ice.
- Once the moisture content of the foods is low enough (usually around 1-4%), they are completely freeze-dried and will be shelf-stable.
