I’m a bit of a freak when it comes to keeping my food fresh. For example, when I buy bread, it goes straight to the freezer just to be certain it won’t begin to mold before I finish the loaf. And milk and fresh vegetables are hard for me to keep up with before they begin getting fuzzy. But Steven Britz of the US Department of Agriculture’s Food Components and Health Laboratory in Beltsville, Maryland, has proposed that UV-lit fridges might be the answer to rotting fruits and vegies. He built a prototype fridge to illuminate store-bought strawberries in a cooler at 95 per cent humidity. After nine days of refrigeration, the fruit showed none of the telltale signs over becoming overly ripe. Win!
