The riper an apple is, the dimmer the glow from the chlorophyll, the researchers said.
You may soon be able to tell if a fruit is ripe or not, thanks to a new handheld device developed by MIT researchers, including one of Indian origin. The device can evaluate how ripe the fruit is by measuring the glow of chlorophyll in the fruit’s skin under ultraviolet light.
Such a gadget could make a big difference for apple distributors, who sometimes have to guess when deciding where to send their stock, researchers said. Testing ripeness could also help farmers decide the best time to harvest their crops. “There’s a tremendous amount of wastage,” said Anshuman Das, a postdoctoral researcher in Massachusetts Institute of Technology (MIT)’s Media Lab.
One solution could be to analyse apples using a spectrometer, which measures the bright…
