16 Aug 2019 --- US agricultural technology firm Cambridge Crops has raised US$4 million in seed funding for a food preservation solution made from silk. Using just salt and water, Cambridge Crops uses natural silk proteins to create a protective layer around food. The technology is applied to slow the exchange of gases that cause decay with an edible film with the aim to “keep food fresher for longer – from strawberries to salmon and everything in between,” shares the company. This pioneering innovation in silk could be another small win in the ongoing battle against global food waste with a “natural” appeal for the consumer.
