WikiCell Designs produces ultra-thin flavored membranes, called WikiCells, that surround liquids or solids shielding them from oxygen, oils, and moisture to extend their shelf life. Unlike Monosol pouches, WikiCells are washable, so the outer container can act like the skin of a fruit. You just wash and eat them.
A WikiCell is made of two sustainable layers. Eat the inner wrapping, compost the shell; no plastic is involved. The inner edible membrane, like a grape skin, is held together by intermolecular electrostatic forces. Positively charged calcium ions bind with alginate, an anionic (negatively charged) polysaccharide from brown algae (Fig. 1). The outer compostable shell is made of the residue from sugarcane crushing.
