It’s clementine season, which means that we’re going through boxes of small citrus fruits each week. Now that we have a little guy, there are always pieces of food that go uneaten, and clementines are no different. But this has prompted me to do some real thinking about orange peels.

Picture it: you peel an orange and inside you’ve got moist, juicy fruit. But leave those wedges out, unprotected, and you rapidly discover that you have nothing but dried-out orange-looking wedges. This means that the thin peel, which seems so insignificant, is doing a really amazing job of keeping moisture inside.

Which got me thinking about medical applications. What if you could keep skin moist by creating a protective layer, like an orange peel? This would be incredibly useful with diabetic wounds, in particular.
