Homework Help: Food Preservation

  1. Mar 17, 2006 #1
    Does anybody have any information on developments in food preservation in the past 100 years? I need to make a poster on it, but I can't seem to find any dates so I can make a timeline.

    I've googled "food safety" "food preservation" etc., but all the sites have more information on the actual substance as opposed to the dates.

    Thank you.

    Drying and freezing are the oldest methods of preservating food. Some other and more recent methods are: vacuum packing, curing, sugar, irradiation...

    See- http://en.wikipedia.org/wiki/Food_preservation , you won't find direct information but it is a good starting point.
