'Transformative Appetite' - 3D-Printed, Shape-Changing Food

Researchers from MIT's Tangible Media Group have basically created edible origami, in the form of flat sheets of gelatin and starch that, when submerged in water, change into 3D structures (including common pasta shapes like macaroni). The researchers used a laboratory 3D printer to pattern cellulose onto films of gelatin. The edible films can be engineered to fold into the shape of a flower, for example, amongst other unconventional configurations. The researchers also created spaghetti that divides into smaller noodles when dunked in hot broth. These edible films could be stacked together and shipped to consumers, then morph into their final shape later, when immersed in water - a practical way to reduce food-shipping costs.
