Why puffed pet food can be welcomed by the market

Puffing is an important part of the dog food processing process. Puffing is a food processing method, which is to put the processed food into a closed container, and suddenly decompress after heating and pressurization, and the moisture in the food vaporizes and expands, so that many small holes appear in the dog food, become crispy, and become puffed dog food. The basic principle is to make the raw materials in the case of heating, pressure and sudden depressurization to make it expand, puffing technology as a new type of food processing technology, started in 1910, the application of pet food in the United States in the 50s of the last century, by the United States first began to use the principle of extrusion to produce pet food, that is, the use of screw and screw sleeve in the extruder through the extrusion of raw materials to make it heated, pressurized, and the high temperature and high pressure of food extruded from the mold hole, due to sudden decompression and the rapid expansion of the volume of the process.

The puffing process is also a process of forming the raw materials of dog food, and the water is added in the form of steam during the molding process, so that the starch of the raw materials in the dog food is gelatinized, and the temperature is raised to 100 °C ~ 180 °C, because the pressure before extrusion is very large, and the pressure is released instantaneously during extrusion, so that the dog food rapidly expands and foams, and the water evaporates, so the dog food that has undergone the puffing manufacturing process generally has high nutritional value that is easy to digest and absorb.

Why is puffed pet food popular in the market?

1. Improve the palatability of dog food, dry dog food, after puffing to become crispy, pet dogs in the process of biting and swallowing, have a better taste and clean oral teeth;
2. Change and improve the nutritional value of dog food, many nutrients need to be matured and puffed before they can become nutritious, otherwise it will not only not bring effective nutrition to pet dogs, but will cause diarrhea, vomiting and other indications;
3. Improve the digestion and absorption rate of dog food for pet dogs, and the puffed dog food pet dogs absorb more comprehensively and perfectly, and there is even a "double puffing" process, the purpose of which is to allow pet dogs to absorb all the nutrients in the dog food more perfectly;
4. Through the puffing and granulation process, the shape and structure of the dog food are changed, so that the pet dog can easily eat the dog food and eat more;
5. Change the content of different nutritional indicators of dog food, such as reducing the moisture content can improve the shelf life of dog food, which is more convenient for pet owners to store and feed anytime and anywhere, which is safe and convenient;
6. Change the density of dog food, extrusion granulation and puffing can also increase the bulk density of dog food, which is convenient for procurement and transportation;
7. The puffing process is also a high-temperature and high-pressure process, which can kill all kinds of mold, salmonella and other harmful substances, and improve the safety and hygiene of dog food.
