(9) Would you eat a two-week-old sandwich?

Long-life lunch will soon be rolling its way to a shop near you.

A two-week-old sandwich doesn’t seem a terribly appetising prospect – bread so stale it’s started to curl at the corners and a filling that’s only distantly related to what it says on the label.
But, according to food scientists, we’ll soon be able to buy and safely eat sandwiches that remain as fresh on day 14 as they were when they were put together. The trick, they say, is in the ingredients and a protective atmosphere inside the packaging.
