Appert then moved out of the use of a bottle of champagne to a wide-necked glass container. In 1803, the results of food preservation which consists of vegetables, fruits, meat, dairy and fish are sent in order to test for the French navy.
A year later in 1804, the plant belongs to Abbert began experimenting with meat cans are sealed and observed for months for detecting whether there are signs of a bubble. No bulging cans that are considered safe to be sold or kept for much longer.

After winning the prize for his contribution to preserving foods, Appert develop these methods for many years - in the midst of the chaos after the collapse of Napoleon's France. His factory still continues to innovate despite a loss, until finally Appert died in poverty in 1841.
At that time, various techniques have been used for the preservation of creation tin of food, ranging from New York oysters, sardines Nantes up to Pennsylvania tomatoes and fruits Italy.
Canned food is very large role in the 19th century as a source of food for the soldiers in the Crimean War, the American Civil War and the Franco-Prussian War, as well as a provision for the explorers.
After the era of global depression in 1873, US exports of canned foods rocketed sharply, led by companies wide Campbell, Heinz and Borden. In 1904, Max Pro Machine Company of New York patented a process of grafting a double (double-seam).
