Canning
Canning is a process of preserving food in which the food is processed and sealed in an air-tight container. Canning can extend the life of food by anywhere from one to five years. First invented in 1810, canning is most commonly used to preserve fruits and vegetables, although other food types can be canned as well. The process of canning is very methodical to ensure that the food does not spoil before or during the canning process.
