To kick off the long, slow process, food and treats are flash-frozen setting the course to locking in the fresh and intense flavors that our pets love!
Next, they are placed on trays and put into a vacuum chamber at sub-zero temperatures (usually ranging from -30 to -50 degrees Fahrenheit). The vacuum chamber gently extracts moisture without the loss of nutrients that happens when food is cooked, baked, or extruded.
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.
Since only water is removed, the food retains the characteristics and natural nutrition of fresh, raw food.
Once the moisture content of the foods is low enough (usually around 1-4%), they are completely freeze-dried and will be shelf-stable.
