The problem with fresh bread is how fleeting it is. Almost a third of all loaves are chucked away before they are eaten in the UK, according to the Department for Environment, Food and Rural Affairs.
But according to the BBC, an American company has developed a technique to keep bread oven-fresh and mould free for 60 days.
Microzap told the BBC that it had developed a type of microwave at Texas Tech University which could kill mould spores in bread in around 10 seconds.
Chief executive Don Stull told the BBC: "We treated a slice of bread in the device, we then checked the mould that was in that bread over time against a control.
"And at 60 days it had the same mould content as it had when it came out of the oven."
Stull said he realised some might be suspicious of the long-life bread. "We'll have to get some consumer acceptance of that. Most people do it by feel and if you still have that quality feel they probably will accept it. "
It would mean that bread manufacturers would not have to use such heavy preservatives to keep bread fresh.
The new method could mean a substantial saving on wasterfood, if the technique is applied to other products like meat or fruit.
In May, the Guardian reported that UK families are wasting £270 a year on discarded food and drink, according to a survey of their kitchen habits by Birds Eye.
