Sometimes biotech gets a bad rap, here's an innovation that counters that perspective.

Chinova Bioworks, co-founded by David Brown, uses fiber from the stems of white button mushrooms to make a natural preservative for foods and beverages. This innovation provides a one-two punch punch against food waste, one of the contributors to global warming. Produced from mushroom stems that would otherwise have been thrown out, it also slows down the action of bacteria, moulds and yeasts that can spoil food. An added bonus is that it has no taste. It's also compatible with consumers who have vegan, kosher, Halal and non-GMO requirements for their food.
