It's challenging for shippers to check the quality of fruit on its way to your grocery store. Most sensors won't reflect the conditions inside the boxes, and plucking a sample isn't going to give you a comprehensive look. That's where some Swiss researchers might come to the rescue. They've created artificial, sensor-packed fruit whose composition is enough like the real thing to provide an accurate representation of temperatures when placed alongside real food. If the fruit in the middle of a delivery isn't properly refrigerated, the shipping company would know very quickly.
