Giant microwave blaster lets bread stay fresh-ish for over 60 days

About a third of the bread that we buy gets tossed out or fed to ducks that don't care if it's stale or gets moldy. You just can't win with bread: either you keep it moist and gross stuff grows on it, or you dry it out and it turns into a rock. A Texas company says it has a solution, in the form of a huge homogenized microwave cannon.

Microwaves, being radiation, work quite well at killing things like fungi. The reason that you can't use your microwave to kill fungi is that your microwave sucks, and due to the wavelength of the microwaves used in microwave ovens (just under five inches), you get hot spots and cold spots that show up at half of that wavelength. Microzap's microwave chamber, on the other hand, works differently, and much better. CEO Don Stull explains:

"We introduce the microwave frequencies in different ways, through a slotted radiator. We get a 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."


This homogeneous signal effectively murders the fungi that causes bread mold in 10 seconds flat, and in testing, the bread was as mold free after 60 days as it was the day after it came out of the oven all fresh-baked and yummy. Since there are no spores in the bread, you can keep it moist for much longer without having to worry about it going bad, meaning that you won't have to deal with that cardboard taste and five-Mohs texture. And in an added bonus, this means that you can do away with most of the artificial preservatives that store-bought bread gets contaminated with.

Microzap says that its attracted lots of interest from bread manufacturers, but the microwave sterilization system works for all kinds of other food too. It's good for vegetables, meats, and most fruits, except for cantaloupes, because they're made of pure evil that not even microwaves can make safe to eat.
