Today, we're learning about food preservation. Rest assured, we canned all our bad jokes before we made this video.

systems for growing storing and shipping food. had to be completely reinvented.
think about it in a small town or smaller city all the food to feed the
citizens could be grown just outside the town .then it could be dragged into town
center and sold directly to consumers at a market. but in a place like go well say
in New York City there's no way there were enough farms closeby to produce
fresh food for everybody. but people still had to eat otherwise you know they
got angry. so to solve the problem we had to invent new methods of storing and
preserving foods. or one of those food dispenser thingies in Star Trek that
totally would have worked too. but the first thing we figured out was how to
can food. yep canning canning is old and traditional. right? beloved by grandma's
everywhere hmm. seriously only grandmas and hipster [woman in mumu holds jar of pickles]
foodies know how to can their own food. we're pretty sure well the truth is that
canning is actually a relatively recent discovery. and at one time it was the
foundation of industrial food production. while canning requires two basic things
to work some type of heat treatment in an airtight container.
well first we bring the food up to a temperature that'll pasteurize it.
as we know pasteurization is the process of boiling all the bad microbes to death.
it's okay they deserve to die after. we've slaughtered all the mean little
squigglies we tightly seal our jar or can. if we've done it right the food in
the jar will last a ridiculously long time .if we've done it wrong and we eat
the canned food later they seriously regret it and the squigglies will have
their revenge. well caning may not sound all that
exciting but it did have an epic beginning. in the 18th century Napoleon
was desperate to find ways to feed his ginormous world conquering army. so he [ napoleon ordering around his men]
offered a prize to anybody who invented a new food preservation technique. well
in 1810 a man named nicholas Appert france there won the prize for his
technique of boiling glass jars of food. canning didn't become a fully fledged
factory process until a few years later once the machines for producing and
assembling tin cans was figured out but then cannons the box.
one of the first canned products to be sold in the US was Borden's condensed
milk. which is disgusting syrup milk but which also allows the caloric value of
milk to be saved long past its expiration date. and the miracle the
Borden's company did especially well during the Civil War selling their
canned milk to soldiers on the move. at least it was better than bleach ridden
swamp water. today with an International freezing and shipping system that allows
there to be fresh blueberries in February in Texas, [cowboy eats blueberry]
canning isn't as all-important as it used to be people are even debating the
health risks of metal pans and the comparative yumminess of you know fresh
food. well these days nothing says I don't feel like cooking like a can of
