Tinned Chicken Soup

My young daughter asked me why the chunks of chicken in tinned chicken soup doesn't need to be refrigerated. I don't know can anyone please shed some light? Is it just because it is in a tin a no bacteria can get to it? TIA

For more on marking an answer as the "Best Answer", please visit our FAQ.The canning process seals the air within the tin. When the soup contents are placed in the tin, it�s warm. As the temperature cools a minor vacuum occurs within the tin, thus preventing bacteria from developing.
Also, which is not very nice to know, certain preservatives may have been included to extend the shelf-life of the product. Finally, there is an additional process called irradiation, or �ionizing.� Using something that resembles the back of an old television picture tube, it points like a gun at the food and penetrates it, sterilising the contents. This protects the �chicken chunks� from deteriorating.
You can help your daughter do her own discovery process by looking at certain products in the supermarket. Bacon, for example is shrink-wrapped, thus removing the air and allowing it to have a longer shelf-life. And there are now many products that have gone through a combination of processes which eliminate the necessity of refrigeration.
Clearly, you have a precocious young lady in your midst! What a gift! I wish you very best regards.

Vicar, the UK in general does NOT irradiate foods. Exceptions to this are spices and some other dried foodstuffs.
It is a legal requirement for all irradiated food to have a declaration on its labelling to state this fact. Look and see how many cans say this.

Hey Zeddy! I agree. However, because our borders have more or less collapsed now (as far as shopping goes), you'll find an increasing number of iirradiated foods. Just a browse through a group such as Lidl or Aldi will show that.
I find the process fascinating, but certainly a concerning one. I think time has moved on sufficiently now to sugges the original concerns are moot. But we never really know, do we? Thanks for the addendum!
