Fruit ripeness predicted by reading leaf chemistry: Light-based technique avoids crop loss

How can you tell if fruit has reached its optimal ripeness without picking it, touching it or carrying out any test that might damage it? A research team from the Department of Analytical Chemistry and Organic Chemistry at the Universitat Rovira i Virgili (URV) has found the answer by applying near- and mid-infrared spectroscopy to the leaves closest to the fruit. They discovered that the technique allows reliable information to be obtained about the fruit's developmental state without damaging it.
