An American company called Microzap has claimed to have discovered a way that could keep bread fresh for up to 60 days. The process involves zapping the bread in a large microwave, which kills the bacteria spores that cause the bread to mold.
The metallic machine uses the same technology as found in commercial microwaves, but with some essential differences. Don Stull, Chief Executive, explains that, “We introduce the microwave frequencies in different ways, through a slotted radiator. We get basically homogeneous signal density in our chamber – in other words, we don’t get the hot and cold spots you get in your home microwave.”
Usually, bread would start to mold in around 10 days. With Microzap’s technology, the process could reduce the growing global problem of food waste. The company states that in the U.K. alone, almost a third of loaves purchased are thrown out.
