History of canning:

Around 1780 Napoleon needed to feed his expedition with meat, fruit, milk, etc. These are perishable foods. But at that time, there was no suitable way to store the food for a long time without deterioration. Napoleon offered a reward to anyone who found these methods. This has prompted some scientists to do research in this area.

In 1795, after ten years of research, a French named Gulas Apel discovered a way to preserve food by hot processing.And it was patented in 1804. And it became the Apel process.

The Englishman Durand obtained a patent to use tinplate

Between 1820 and 1880, it was discovered that adding salt to a can of boiling water raised the boiling point from 100 degrees Celsius to 115 degrees Celsius.This reduces the sterilization time.
