How the tin can changed the world

BBC:

Tin cans have, in 200 years, changed the way the world eats. But Victorian disgust over a cheap meat scandal almost consigned the invention to rejection and failure.

Bryan Donkin left the chimney smoke of the city behind as his carriage headed south through Bermondsey, with the Duke of Kent's letter of approval in his hand.

The smell of leather and hops receded as he came to the turnpike at Fort Place Gate, where the gatekeeper's two-storey, brick house marked the end of the urban sprawl.

Behind him was an unhindered view of St Paul's Cathedral while in front lay open land and his factory, where for the previous two years he had been trying to find the best ways to can food.

He could not have known that the impact from the contents of the papers he held would still be felt across the globe 200 years later.

Dated 30 June 1813, the day before, the letter explained that four distinguished members of the royal family - including Queen Charlotte, wife and consort of King George III - had tasted and enjoyed his canned beef.

Indulging such refined palates was not a matter of vanity for this modest Northumbrian engineer.

Instead, it meant he had the highest possible blessing to supply what are thought to be the world's first commercial cans of preserved food to the Admiralty, thereby sparing British seamen thousands of miles away the monotony of salted meat.

According to his diaries, held at Derbyshire Records Office in Matlock, the can-making operation had begun to mobilise on Monday 3 May.

A network of agents was based at key seaports to tout for custom from naval ships and merchants. The patent was finally his, the meat suppliers paid and adverts placed in newspapers, while business cards were engraved with the name of the company - Donkin, Hall and Gamble.

The factory occupied a rectangular plot of about 300 sq m, dwarfed by Donkin's larger plant for papermaking machines.

In the weeks that followed, within those four walls, sheets of tin plate were transformed by hand into tin cans filled with beef, mutton, carrots, parsnips and soup, destined for every corner of theBritish Empire.

And so the first faltering steps of a multi-billion-pound business were made. Today, households in Europe and the US alone get through 40 billion cans of food a year, according to the Can Manufacturers Institute in Washington DC.

...

There is much more.

It was not just the Royal Navy that used the new wonder.  The British army also marched with canned food. In World War II the US military survived on C-ratrions which had various canned foods packaged in a box for each meal.  With a few changes in the menu we had some of the same food in Vietnam.  In recent years the "meals ready to eat" come in foil pouches.  But I would be willing to bet you have a lot of canned goods in your pantry right now.  The process of reserving the food was also developed in France at around the same time though they preserved it in jars.
