How about freeze-dried pet food?
There are generally three processing techniques for the staple food of pets. One is traditional puffed food, and the other is freeze-dried food.
Puffed grains are mainly made by high-temperature puffing of raw materials, and the process is divided into dry puffing and wet puffing. The puffing process can kill various molds, salmonella and other harmful substances, change the shape of food, and make it easier for pets to eat in their stomachs. At the same time, puffed food is beneficial to pets' gastrointestinal digestion. However, at the same time, puffed grains are also conducive to a certain loss of nutrients in raw materials. For example, during processing, nutrients such as amino acids, vitamins, carotene, and inorganic salts in the raw materials will be greatly destroyed, and nutrients need to be added.
The production process of freeze-dried grain is to adopt low-temperature vacuum freeze-drying method, which can retain the nutrients of the raw materials to the greatest extent and has good palatability. However, the processing cost is relatively expensive, which leads to high prices.
