It's pretty cool when the worlds of science and food collide. At least one Harvard professor is doing so with WikiPearl. The idea comes from natural fruit skin, where the flesh is protected from the environment by an edible skin. They've partnered with Stonyfield for this edible packaging idea in their frozen yogurt pearls, creating frozen yogurt you can eat with your hands.
For me, the idea has not completely replaced regular retail packaging, since you still have to package the wiki pearls, but one day we can hopefully minimize it since you don't have to package each pearls separately. The WikiPearl skin doesn't melt so putting two together won't make them stick to each other or cross contaminate the others. You can see below the frozen yogurt inside a pearl. With Stonyfield's products, the skin is also flavored, creating different combinations between the yogurt and the skin.
