Wasting food costs us an extraordinary amount of money. According to the RAP group, the average family throws £680 of food away every year - which adds up to an astonishing 7.2 million tonnes of food. In most of these cases, we have optimistically bought something and simply not got around to using it before it forms a mouldy mush in the bottom of the fridge.
But a new invention could dramatically transform those figures.
InventionBread is one of the worst offenders when it comes to sneakily going green when it disappears out of sight in the bread bin - apparently almost a third of all the bread we buy goes into the bin.
Now an American firm has invented a way to keep bread free from mould for 60 days - up from roughly 10 days when it's not treated.
According to a BBC report, it is zapped in a kind of microwave, which kills mould spores. The invention could also work wonders on the longevity of everything from turkey to fresh vegetables.
It would have the added advantage that manufacturers could use fewer preservatives - and fewer ingredients to cover up the taste of the preservatives - so we'd have fewer chemicals in our food too.
ButThere's a downside though: unfortunately these zapping machines aren't cheap to buy or run, so using them would push up the cost of bread in an insanely competitive market where margins are already tiny. It may just not pay anyone to use this invention.
Plus, there's the PR problem of getting people to be happy eating very old bread.
The experts suggest that there's still so much that we can do in the home to cut down on waste without expensive inventions. If you have leftover slices of bread that are past their best, it may make more sense to blitz them in the food processor and turn them into bread crumbs - or tear them up and put them into tomato salad.
Likewise we should think harder about what we buy, how much we cook, and how we store food. This could help us waste less than 50% of the food we currently throw away - without the need for fancy inventions that will lead to more expensive bread.
In many cases, planning a week of meals and checking the cupboards before we go shopping could cut waste by even more than 50%.
But what do you think? Would it bother you if your bread was two months old, or is this a brilliant solution? let us know in the comments.
