How does canning work ?

In canning, food is boiled and immediately sealed . Boiling kills bacteria and sealing prevents new ones entering. Now the food in the can is completely sterile and so does not spoil. But as soon as you open the can, bacteria enter and begin attacking the food.

Stock up on your favorite canned stuff. They are indispensible in camping and in disaster management.
