Strawberries that weren\u2019t dipped in the solution changed color and became dehydrated under the same conditions, on their way to going bad.<\/p>\n<p>Fiorenzo Omenetto, one of the scientists, says that the coating works by inhibiting fruit respiration. Uncoated strawberries release carbon dioxide, oxygen and water vapor in a process that eventually leads to spoilage, but a few dips in the silk solution limited this discharge. The key, Dr. Omenetto says, is getting the silk protein to form the proper crystalline structure, which is done by treating the dipped strawberries with water vapor. Once they are picked, strawberries do not ripen any further. Bananas do, and the researchers found that their technology slowed their ripening.<\/p>\n<p><i>Click for more from The Wall Street Journal.<\/i><\/a><\/p>\n<p>\u00a0<\/p>\n<p><i \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Food waste is a big problem, and produce is particularly vulnerable.
