Technical Field

The invention relates to a pet food processing technology, in particular to a light processing technology capable of improving the digestibility of pet food, and belongs to the field of food processing.

Background

With the increasing importance of pet-raising users to pets, the dietary habits and the exercise amounts of pets are gradually changing. This is accompanied by a continuing decline in the digestibility of pet foods, and the low digestibility of pet foods has not been effectively addressed by current pet food formula components. The problem of intestinal dysfunction caused by low digestibility of pet food has already influenced the health of pets and the pet-raising experience of pet breeders. CN109043205A discloses a manufacturing method of pet food, which provides a pet dog food that can increase palatability and improve digestibility of food, but this method is a domestic feed preparation method, is not suitable for industrial production, and no specific digestibility effect is presented in the examples. To ameliorate this situation, the present invention provides a light process that can increase the digestibility of pet foods.
