  4. Canning History Lesson Canning dates to late 18th century in France. Napoleon Bonaparte, concerned about keeping his armies fed, offered cash for developing a reliable method of food preservation. Nicholas Appert won the prize, 12,000 francs, in 1809 when he submitted his method of “food in glass bottles (Kovel and Kovel, 2007). Home Food Preservation 4

  5. Canning History Appert used glass jars sealed with wax and reinforced with wire. Took 14 years to develop. Peter Durand, in 1810, replaced the breakable glass bottles with cylindrical tinplate canisters. Tin Can Openers were not invented for another 30 years. Home Food Preservation 5

  6. Basics haven’t changed drastically The basic principles have not changed dramatically. Heat sufficient to destroy microorganisms. Foods packed into sealed, or "airtight" containers. The canned foods are then heated under steam pressure at temperatures of 240-250°F (116-121°C). Home Food Preservation 6

  7. The Basics Louis Pasteur provided the explanation for canning when he was able to demonstrate that the growth of microorganisms is the cause of food spoilage (Lund et al. Eds. 2000). Home Food Preservation 7

  15. Home Canning Survey Majority of home canners have reported not following science-based home preservation methods. Receive much of their home preservation information through friends and family. Only 45% of respondents thought that home canned foods could be spoiled without obvious signs of spoilage. Home Food Preservation 15
