Can You Eat 60 Day Old Bread?

It is said to be the best thing after sliced bread. It’s bread that can last for 60 days. An American company called Microzap says it has developed a technique that will keep bread mould free for two months. Under normal circumstances, bread will go mouldy around 10 days, but the Texas-based company, uses a special microwave that kills the mold spores in your bread in 10 seconds. Now that bread that goes bad in 10 days will last for about 60 mold-free days.

The bread is zapped in a sophisticated microwave array which kills the spores that cause the problem. The equipment was originally developed to kill organisms like multi-resistant staph bacteria and salmonella. But its developers realized it also kills bread mold in about a 10-second zap. It works much like a home microwave, but the waves are produced in various frequencies, which allows for uniform heating.
The company claims it could significantly reduce the amount of wasted bread and the technique can also be used with a wide range of foods including fresh turkey and many fruits and vegetables.
One of the biggest threats to bread is mould. As loaves are usually wrapped in plastic, any water in the bread that evaporates from within is trapped and makes the surface moist. This provides excellent growing conditions for Rhizopus stolonifer, the fungus that leads to mould.
The technology could also impact bread in other ways. Bread manufacturers add lots of preservatives to try and fight mould, but then add extra chemicals to mask the taste of the preservatives. If bakers were able to use the microwave technology, they would be able to avoid these additives.
The company's device has attracted plenty of interest from bread manufacturers - but it is worried that it could push up costs. And there is also a concern that consumers might not take to bread that lasts for so long.
