10 Apr 2019 --- Seattle-based start-up StixFresh has developed a sticker that can keep fruit and vegetables fresh for up to two weeks longer than usual. When applied to the fruit, the all-natural compound contained on the sticker creates a protective layer around the fruit that increases its shelf-life, reducing food waste at home or anywhere along the post-harvest supply chain. Stixfresh anticipates commercial release by August 2019.
