A truism as old as strawberry picking is the observation that the juicier and tastier the strawberries, the more quickly the berries turn to a mushy heap of rot and mold, even in the fridge. An answer to longer fruit storage may come with research showing that selective UV light inhibits both decay and the growth of mold.
