Or is there? Sensor Electronic Technology, Inc. (SETi) has developed technology with produces only UV-B rays, which have been shown to not only kill mold and decay on produce but that does not dry out it out as UV-C rays do. This has the potential to keep berries fresher longer (USDA testing showed treated berries staying mold-free for nine days, which if you regularly eat strawberries you know is something of a miracle). Normally, when you buy strawberries you keep them in the refrigerator in hopes of them lasting longer, which means they're being stored in the dark. Dark breeds mold, especially in what is traditionally a moist environment like your refrigerator's produce drawers.
The best part about this new technology is the devices are low-power and work well in cold environments, making them ideal for use in refrigerators. This new technology is still in testing, but it wouldn't surprise me to see it included standard on refrigerators in a few years. Imagine how much money you'll save if you can keep strawberries, which are notorious for getting moldy sometimes within a day or two of bringing them home, for over a week! And of course it can also be used on other produce to similar effect. I can't wait to see this one commercially available.
