Nicolas Appert, the "Father of Canning", Inventor of Airtight Food Preservation

Food Preservation

For more than ten thousand years, humans have preserve food using different methods: drying, curing, smoking, sugaring, salting, fermenting, cooling, etc...

Most of these methods change the taste of the food significantly.

A new method for preserving food was invented by a French confectioner named Nicolas Appert at the end of the XVIIIth century in Paris.

At some point during my career in the French Navy, I was living in Brest on a square called "place Nicolas Appert", and that is how I learned of Mr Appert and his invention.

Nicolas Appert was the son of inn keeper from Châlons-sur-Marne. During his youth he learned food preparation and the various methods of food preservation.

He worked as a personal chef to rich people for twelve years. Then, in 1784, at the age of 35, he moved to Paris and opened a confectionery store named "La Renommée" (The Fame).

Taking into account several criteria (modification of taste, high cost and poor nutritional qualities of salted, dried, smoked and sugared products), in 1795, he started to develop the process that made possible the canning of food (originally called "appertisation").

Appertization can be defined as a conservation process consisting in heat sterilizing perishable foodstuffs in hermetic containers.

Preserving Food in Glass Containers

The containers Nicolas Appert used were thick, large-mouthed glass bottles.

He would fill these bottles with produce of every description, ranging from beef, fowl, eggs, milk, and prepared dishes.

His greatest success for publicity was an entire sheep. He left air space at the top of the bottle, and the cork would then be sealed firmly in the jar by using a vise. The bottle was then wrapped in canvas to protect it, while it was dunked into boiling water and then boiled for as much time as Appert deemed appropriate for cooking the contents thoroughly.

In 1802, he founded in Massy the first preserving factory in the world, where he employs a dozen and then some fifty workers.

He submitted his invention to the French Navy that was delighted to have finally a good way to preserve all kinds of foodstuff for the long trips of ships.
The Navy gave Nicolas Appert two options: either he get a patent or he makes his invention available to everybody and he gets a grant from the French government.

Nicolas Appert opts for the second solution, preferring to make humanity benefit from its discovery rather than enrich itself.

In 1810, he got a grant of 12,000 francs. The same year he publishes a book: "L'Art de conserver les substances animales et végétales" (The Art of Preserving Animal and Vegetable Substances).

This was the first cookbook of its kind on modern food preservation methods. [Wikipedia]

Canning

Unfortunately for Nicolas Appert, his glass bottles were not very practical, because they were fragile.

Appert's method was so simple and workable that it quickly became widespread. In 1810, British inventor and merchant Peter Durand also of French origin, patented his own method, but this time in a tin can, so creating the modern-day process of canning foods.

Although these tin cans were not initially very practical (you needed a hammer and chisel to open the cans), they were more robust than the glass bottles of Nicolas Appert. Canning became widespread after the invention in 1855 of the can opener by Robert Yeates, a cutlery and surgical instrument maker in Middlesex, England.

Competition from the British, favored by access to a better quality and less expensive tinplate, eventually ruined Appert.

In 1840, he sold his company, and on June 1st 1841, widower, without money to offer himself a burial, Appert died in Massy, where his body is deposited in the pauper's grave.

This is how the story of Nicolas Appert, a benefactor of humanity, ends.
