Silk protein can be applied as an edible food coating to extend the shelf life of food products by slowing dehydration and reducing oxidative stresses. Here, we highlight the commercialization of Mori Silk, from lab discovery and first proof of concept to manufacturing, scale-up, field validation, regulatory approval and forward-looking challenges.
