Yes, freeze-dried food retains the nutrients of its ingredients exceptionally well. The freeze-drying process involves freezing the food and then removing moisture through a process called sublimation, where ice transitions directly into vapor without passing through a liquid phase. This method preserves the nutritional integrity of the ingredients, including vitamins, minerals, and proteins, as it does not involve high heat or prolonged exposure to oxygen, which can degrade nutrients. As a result, freeze-dried food maintains its nutritional value, making it an excellent choice for providing your pet with a diet rich in essential nutrients.
