Military researchers have been working on the goal of long-life pizza for years. It's described as their "holy grail."

Scientists at the U.S. Army Natick Soldier Research, Development and Engineering Center, in Natick, Massachusetts, have been trying to combat pizza's inherent tendency to go soggy - and, as a result, mouldy.

Pizza has been one of the most requested additions to the army's MRE (Meal Ready to Eat) roster.

Food scientist Michelle Richardson (above) says of the pizza prototype: "You can basically take the pizza, leave it on the counter, packaged, for three years and it'd still be edible."

The key has been finding a way to stop the dough getting moist.

This includes adding ingredients that bind to water in the tomato sauce and toppings, preventing it from migrating to the dough, and altering the acidity of the ingredients so bacteria are less likely to grow.
