Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have come up with edible food packaging they've called WikiCells that could potentially solve society's food waste problem. The edible, artificial material is made of food particles and a charged polymer liquid, according to Organic Authority, and was inspired by grapes. WikiCells are hardened around foods, forming a barrier like an eggshell.
Professor David A. Edwards, who heads up the team that created WikiCells, hopes to have the material in publicly available products within a year or so. For another innovative edible, check out this gin paper.
