systems for growing storing and shipping food. had to be completely reinvented.

00:31

think about it in a small town or smaller city all the food to feed the

00:36

citizens could be grown just outside the town .then it could be dragged into town

00:41

center and sold directly to consumers at a market. but in a place like go well say

00:46

in New York City there's no way there were enough farms closeby to produce

00:50

fresh food for everybody. but people still had to eat otherwise you know they

00:55

got angry. so to solve the problem we had to invent new methods of storing and

01:00

preserving foods. or one of those food dispenser thingies in Star Trek that

01:05

totally would have worked too. but the first thing we figured out was how to

01:09

can food. yep canning canning is old and traditional. right? beloved by grandma's

01:15

everywhere hmm. seriously only grandmas and hipster [woman in mumu holds jar of pickles]

01:19

foodies know how to can their own food. we're pretty sure well the truth is that

01:23

canning is actually a relatively recent discovery. and at one time it was the

01:30

foundation of industrial food production. while canning requires two basic things

01:36

to work some type of heat treatment in an airtight container.

01:40

well first we bring the food up to a temperature that'll pasteurize it.

01:44

as we know pasteurization is the process of boiling all the bad microbes to death.

01:50

it's okay they deserve to die after. we've slaughtered all the mean little

01:56

squigglies we tightly seal our jar or can. if we've done it right the food in

02:01

the jar will last a ridiculously long time .if we've done it wrong and we eat

02:06

the canned food later they seriously regret it and the squigglies will have

02:10

their revenge. well caning may not sound all that

02:13

exciting but it did have an epic beginning. in the 18th century Napoleon

02:17

was desperate to find ways to feed his ginormous world conquering army. so he [ napoleon ordering around his men]

02:21

offered a prize to anybody who invented a new food preservation technique. well

02:27

in 1810 a man named nicholas Appert france there won the prize for his

02:33

technique of boiling glass jars of food. canning didn't become a fully fledged

02:39

factory process until a few years later once the machines for producing and

02:43

assembling tin cans was figured out but then cannons the box.

02:47

one of the first canned products to be sold in the US was Borden's condensed

02:52

milk. which is disgusting syrup milk but which also allows the caloric value of

02:57

milk to be saved long past its expiration date. and the miracle the

03:02

Borden's company did especially well during the Civil War selling their

03:06

canned milk to soldiers on the move. at least it was better than bleach ridden

03:11

swamp water. today with an International freezing and shipping system that allows

03:17

there to be fresh blueberries in February in Texas, [cowboy eats blueberry]

03:21

canning isn't as all-important as it used to be people are even debating the

03:25

health risks of metal pans and the comparative yumminess of you know fresh

03:30

food. well these days nothing says I don't feel like cooking like a can of

03:35
