With the advancement of technology, the pet industry also develops. In recent years, more and more diverse pet snacks have occupied the market, making pet owners confused. Among them, the two "most alike" ones are dried snacks and freeze-dried snacks. They are all dried meat snacks, but both have their own characteristics in terms of taste and nutritional content.

Process difference

Freeze-drying: Freeze-drying technology is a process of dehydrating food in an extremely low temperature environment under vacuum. The water will be directly converted from solid to gas, and there is no need for sublimation to transform into an intermediate liquid state. During this process, the product will maintain its original size and shape, the smallest cells will rupture, and moisture will be removed to prevent the food from spoiling at room temperature. The freeze-dried product has the same size and shape as the original frozen material, has good stability, and can be rebuilt and restored when placed in water.

Drying: Drying, also known as thermal drying, is a drying process that uses a heat carrier and a wet carrier to cooperate with each other. Usually hot air is used as a heat and a wet carrier at the same time, which is to heat the air and then let the air heat the food, and the moisture of the food evaporates Then it is taken away by the air and discharged.

Composition difference

Freeze-dried: Freeze-dried pet food generally uses natural animal muscles, internal organs, fish and shrimp, fruits, and vegetables as raw materials. The vacuum freeze-drying technology can completely kill the microorganisms in the raw materials. And during the production process, only the water is completely extracted, without affecting other nutrients. And because the raw materials are thoroughly dried and are not easily deteriorated at room temperature, most freeze-dried snacks are made without preservatives.

how to choose

Affected by the ingredients and production process, freeze-dried snacks and dried snacks have formed their own different taste and flavor, and they also have their own differences in eating. How to choose suitable snacks for your own Mao children can be considered based on the following aspects.

Freeze-drying: Freeze-dried snacks use a low temperature + vacuum process to directly "pull" water molecules out of the cells. When the water molecules come out, they will destroy some smaller cells and form a sponge-like structure inside the meat. This structure makes freeze-dried meat have a soft taste and strong water-richness, suitable for dogs and cats with weak teeth. You can also soak in water or goat's milk to rehydrate the meat and feed it. This is also a great way to trick them into drinking water when facing hairy children who don't like to drink water.

Drying: Drying snacks drives away moisture by heating up. Because the effect of thermal drying on the food is the temperature from the outside to the inside and the humidity from the inside to the outside (the opposite), the surface of the meat will shrink more drastically than the internal drying. This change gives the dried meat more strength Taste, so compared to freeze-dried snacks, dried snacks are more suitable for young and middle-aged dogs with teething needs. Using this feature, you can give food a richer appearance and make the food more interesting, such as lollipops and meatballs. Sandwiches, etc., increase the interaction between the owner and the pet.
