Dog Food Puffy Processing Method

Dog food processing mainly uses various means and methods to shape a variety of raw materials or a single raw material for improving the nutrition, palatability, digestion, and absorption capacity of dog food, so as to exert potential nutritional value and use value.

The processing range of dog food is very wide, including snack food, snacks, tooth cleaning sticks, bone, bone pressing, nutrients (liquid), concentrated dog food powder, dry food, wet food, semi-dry food, canned food, etc. Different raw materials are processed to different degrees in order to maximize their nutritional functionality.

The processing of puffed food has mainly three categories: physical method, chemical method, and microbial method. The physical method refers to the extrusion, heating, pulverization, and bonding of raw materials; The chemical method is to denature starch and degrade proteins; The microbial method is to let a certain raw material ferment. Here is a brief introduction to the puffing process in the physical method.

The main purpose of the puffing process for dog food is:

1. Improve the palatability, nutritional value, digestion, and absorption rate  of pet food;

2. Change the shape and structure of pet food to make it easier for pets to eat;

3. Change the content of different nutritional indicators of pet food, such as: reducing the water content to improve the shelf life of the food, which is conducive to storage;

4. Change the bulk density of food, extrusion granulation, briquetting to increase the bulk density of food;

5. Kill all kinds of mold, salmonella, and other harmful substances, and improve the safety and hygiene of pet food.

In the processing technology of dog food, the extrusion process has been widely used in pet dry food, semi-dry food, and pet snack food in recent years. Meanwhile, technology has greatly also improved palatability, nutrition, digestion and absorption, sanitation and safety, transportation, storage, and other aspects of pet food.
