If you like avocados, you've probably been forced to toss out a few that got too ripe, too fast. One company is hoping to end the waste with a new plant-based coating that slows decay. Apeel, backed with funding from the Bill & Melinda Gates Foundation, among others, claims produce sprayed with its creation will last at least twice as long as regular produce. Roughly 1,100 Krogers are set to start selling these longer-life avocados, while asparagus and limes with similar coating will be available in a Cincinnati pilot program.
