27 Oct 2021 --- UK recipe box service Gousto is trialing an edible wrapper made from pea protein and potato starch for its bouillon cubes. The cubes and their packaging can be dissolved by being dropped into hot water, as a replacement for existing stock mix sachets. The edible packaging is made by engineering and drying a pea protein material into sheets that have the same benefits as plastic, preserving the food’s flavor and shelf life. The material is also vegan and gluten-free.
