Two owners of a company have come up with a way of letting you know when food has gone off. Mats Nygardhi and Henry Norrby created a device that destroys barcodes on food products when the item is at the wrong temperature and has gone bad.
This means customers will be able to know whether the food is off even before taking it to the checkout (now THAT scares us!). Mats, who owns Swedish company Tempix, hopes to sell the handy device to Tesco and Asda.
The innovators discovered the idea when they were talking about the crystals found on frozen tubs of ice cream.
“We found if you bought ice cream you can find ice crystals on the package,” said Mats, 53.
“So we came up with the idea of an indicator, which destroys the barcode when the product is at the wrong temperature, meaning the customer knows before he takes it to the till,” Mats added.
What do you think of this idea?
