For the development of a smart food chain, it is necessary to produce stable high-qualityagricultural products in the agricultural sector which is the starting point of the foodsystem, and it is important to accumulate and analyse the phenotypic information ofagricultural products during cultivation. An easy, rapid, non-destructive and quantitativeevaluation method of tree vigor is desirable. This study aimed to develop an X-rayfluorescent (XRF) spectroscopy of fresh leaves and infrared (IR) spectroscopy of fruitjuice using a portable device. In addition, the relationship between the spectroscopicinformation and the surface color of agricultural products was studied. The results showedthat the changes in leaf element were in balance and organic matters in the fruits due toslight differences in cultivation conditions were grasped as the XRF and IR spectroscopicinformation. Furthermore, such changes could be reflected as the differences in the surfacecolor information obtained using the digital camera. Therefore, it was experimentallysuggested that the multiband optical sensing could be a powerful and important tool forrealizing smart food chains and phenomics research starting from agricultural production.
