Hello, there are many ways to preserve Jianyang light cakes, which are similar to those of dry food eaten at home at ordinary times. Here are some examples:

First of all, after eating Jianyang Guanggao, you can find a vacuum sealed bag, so that the food will not be eaten by exotic species, such as flies, mice and other small animals, because of contact with the air.

The second is to store it in a relatively dry place, and don't let it get wet, because once it gets wet, it means there is water vapor, and food exposed to water vapor for a long time will be prone to mildew, and bacteria will stay on food, so people who eat it will cause various diseases, such as food poisoning and stomach discomfort. They will have to go to the hospital and they will have to spend another sum of money.

Of course, every food has its own shelf life, and we will also pay attention to this problem during the production process. If we make food, Jianyang light cake will be baked like ordinary biscuits, so the shelf life will last for two or three days, and it is a famous snack in history. We will do our best within the shelf life!

I hope my answer can help you!
