One of the most important causes for medium term food storage problems is oxidation: home-made fruit juices start to look strange, the apple pulp goes brown, butter gets a funny taste, the tomato pulp turns to dark red jelly, and so on.
So why not create an airtight container which de-oxigenates the
air caught inside? The first thought that comes to *my* mind is a "clean" flame (i.e. not burning a match which leaves carbon monoxide and other nasty chemicals behind), but I'm sure a chemist could come up with a much more elegant solution for this. So, any chemists around? :-)

I like this idea, but I'm leaving it neutral until I see an implementation method better than flame. |
|
| |
Doesn't fire need oxygen to survive? Bad Science? |
|
| |
Although this may be used to grow anaerobic bactieria. |
|
| |
I think there are devices for recorking wine that inject nitrogen into the bottle - similar in principle to this. |
|
| |
There are also little cartridges one can use for the culture of anaerobic bacteria which react away all the oxygen in a container. I think they are some sort of sulfur compund. Probably more thorough than a flame, which will go out before consuming all oxygen. |
|

[bungston] is correct, although i'm not sure about the sulfur. the way i recall it, the cartridges or packets give off hydrogen when water is added, which in turn reacts with oxygen in the presence of a metal catalyst. i'll try and find a link. |

I've found that I can remove most if not
all of the oxygen inside a 23 litre
container by filling it with freshly
brewed beer - the
continuing fermentation usually results
in a blanket of some gas or other that
isn't as harmful as oxygen, and it
causes pressurisation of the keg. |
|
| |
So beer will keep indefinitely? |
|
| |
Don't know. Nobody's ever seen it
happen yet. |
|

This is an issue for house-painters. At least I think that's where I read about preserving paint in cans by filling them with various gasses. There were several suggestions, including carefully filling the can with butane from a lighter. |
|
| |
Me, I'd drop in a chunk of dry ice and let the container fill with CO2. |
|
| |
Ugh. Freezer burn. I'm with the painters ... keepers of the bowels immortal. |
|
| |
There's a sachet in some products that removes the Oxygen - usually in tins of peanuts. It usually says "Do not eat" on the side. |
|
| |
I can only assume that Oxygen is poisonous and should not be eaten. |
