Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, [a] although under specific circumstances, it can be much longer. [2]
Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker . A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 ...

John Landis Mason, inventor of the Mason jar. In 1858, a Vineland, New Jersey tinsmith named John Landis Mason (1832–1902) invented and patented a screw threaded glass jar or bottle that became known as the Mason jar (U.S. Patent No. 22,186.) [1] [2] From 1857, when it was first patented, to the present, Mason jars have had hundreds of variations in shape and cap design. [8]
Canning involves cooking food, sealing it in sterilized cans or jars, and boiling the containers to kill or weaken any remaining bacteria as a form of sterilization. It was invented by the French confectioner Nicolas Appert. [4] By 1806, this process was used by the French Navy to preserve meat, fruit, vegetables, and even milk.
The process wasn't called canning then and Appert did not really know the principle on which his process worked, but canning has had a major impact on food preservation techniques. Louis Pasteur 's research on the spoilage of wine and his description of how to avoid spoilage in 1864, was an early attempt to apply scientific knowledge to food ...
A potted meat food product is a food preserved by canning and consisting of various seasoned cooked meats, often puréed, minced, or ground, which is heat-processed and sealed into small cans. Various meats, such as beef, pork, chicken, and turkey, are used. It is produced primarily as a source of affordable meat.
During the 1800s, [6] the canning process was mechanised and refined, with can walls becoming thinner. The twist-key can-opener was patented by J. Osterhoudt in 1866. [ 7 ] There still was no general-purpose can-opener, thus each can came with a spot-welded or soldered-on twist-key can-opener which snapped off after fatiguing the metal by ...
