Researchers at Nagoya University and engineers at NARO in Japan have apparently found a way to "control the perfection of strawberries," in order to control the ripeness of each fruit without any manipulation, as reported on francetvinfo.fr.
According to the tests carried out, fruit with the highest sugar content reacts differently to near-infrared waves. The signal bounces off the fruit and returns to the transmitter for analysis.
Prolonging the freshness of fruit and vegetables
Japanese agricultural engineers are also using these waves for other purposes. Researchers at the Shikoku Research Institute, for example, have developed a flash of near-infrared light. "They claim that exposing fruit and vegetables to 0.1 seconds of these infrared waves after harvest extends their freshness by several days. This technique, which they have called IR Fresh, works on citrus fruit and tomatoes, but also on all leafy vegetables."
