creates invention? In the late 18th century Emperor
Napoleon Bonaparte, concerned about keeping his armies
fed, offered a cash prize to whoever could develop a
reliable method of food preservation. The canning process
dates back to France when Nicholas Appert conceived the
idea of preserving food in bottles, like wine. After 15
years of experimentation, he realized if food is
sufficiently heated and sealed in an airtight container,
it will not spoil.
Englishman, Peter Durand, took the process one step
farther and developed a method of sealing food into
unbreakable tin containers, which was perfected by Bryan
Dorkin and John Hall, who set up the first commercial
canning factory in England in 1813. As more and more of
the world was explored, and as provisioning armies took on
greater importance, the demand for canned foods grew.
Thomas Kensett, who emigrated to the United States,
established the first U.S. canning facility for oysters,
meats, fruits and vegetables.
principles of canning have not changed dramatically since
its beginning. Heat sufficient to destroy microorganisms
is applied to foods packed into sealed, or "airtight"
containers. The canned foods are then heated under steam
pressure at temperatures of 240-250 degrees. The amount of
time needed for processing is different for each food,
depending on the food's acidity, density and ability to
World War II, many varieties and innovations occurred to
bring food to fighting troops. Spam became the favorite
among American G.I.s.
