France and England
Nicolas Appert described preserving food in sealed glass jars in 1810 after developing it around 1809. Peter Durand patented tin cans in England in 1810.
Appert won a prize offered by the French government. The cause of spoilage, microbes, was not understood until Pasteur’s work decades later.
The world before
Food was preserved by drying, salting, smoking or pickling, which changed its taste and texture.
The human achievement
Appert filled glass jars with food, corked and sealed them, then boiled them for hours. Durand patented a tin container, and the first English cannery opened in 1813. Early cans were heavy and opened with hammer and chisel; the can opener appeared decades later.
Understanding the invention
Canning, explained in two steps.
Step 01 of 02
Heating destroys most organisms that cause spoilage.
IV
The transformation
Soldiers and sailors could be supplied with safe food on campaigns.
Fruit and vegetables could be eaten out of season.
It allowed armies, ships and cities to be fed from stocks, and later let households keep food through the winter.
Before and after
Before
Salted meat and root crops.
After
Preserved peas and fruit from a tin.
