How long can hamburgers be kept?

I believe many people like hamburgers very much. Hamburg belongs to western food and is also a kind of fast food. Burgers that can't be stored for a long time, such as KFC, McDonald's and other fast food brands, are now made and sold by themselves. How long can hamburgers be kept?

1, the shelf life of hamburgers is 24 hours at room temperature, and it can be extended to 2 days if it is kept in the refrigerator.

It's best to wrap a food preservation bag, then put it in the refrigerator, take it out in advance when eating the next day, and then heat it in the microwave oven, or use that if you have a small oven. When the microwave is hot, take off the paper outside the hamburger, put it in the microwave lunch box, sprinkle some water on the side with your fingers, and put it in for microwave heating.

In addition, if the weather is cold enough, just wrap the fresh-keeping bag and put it in a ventilated place, such as a window, all night.

Hamburgers turn sour easily because they contain fried meat and salad dressing. When stored, they must be isolated from the air and kept at a low temperature. You can buy less next time if you don't want to waste it.
