The process of canning was developed by Nicolas Appert, a French chef and food preservationist, in the early 19th century. He discovered that food could be preserved by sealing it in glass jars and heating them, which prevents spoilage by killing bacteria. Appert's methods were later adapted for use with metal cans, leading to the modern canning process we know today. His work laid the foundation for the food preservation techniques that are widely used around the world.
In 1810, Nicolas Appert developed canning under the direction of Napoleon Bonaparte. Also in 1810, Peter Durand patented the process of canning in tin cans in England.
The first practical canning process was developed by Nicolas Appert in the early years of the 19th century.

The process of soft canning is more of a combination of canning and vacuum sealing. The food is preserved in a package that may be left at room temperature until it has been opened. Once you have opened the package, the food must be refrigerated or frozen to avoid bacterial growth.
