The
invention of canning process
Canning is the process that in fact had
been found since 1809 during Napoleon and the French Army era. That time, a man
called Nicholas Appert developed some method to cook a food inside a sealed
glass jar and the food would not spoil unless the seal or the cover was broken.

cylinder invention that associated with cans and soon in 1903; finally the
canned tuna was first introduced to the market in United States until now.
Why canning
can work to make the tuna fish inside staying fresh?
The tuna fish canning factory process can make the tuna meats inside staying fresh for
several reasons. Canning process works by sealing the tuna (this process
applied as well to the other canned fish like sardines, tuna, etc) plus the air
that might be inside the container and after that cooking it. With this cooking
process, it will sterilize the interior contents and it manages to kill
bacterial which can cause spoilage. As long as the cans are undamaged, new
bacteria cannot reach the tuna inside. However some foods may require other
additional measures with acids or salts while other factories prefer to use
ionizing radiation to replace this cooking process. In conclusion, the tuna
fish should be canned under pressure in order to make the meats staying fresh
as longer as possible.
Some extra notes that not all bacteria can
be killed with cooking process or at least not with the temperature that used
in canning. For example, bacteria such as the member of botulism family cannot
be killed with canning process.
