. Contrastingly, thebags used for fresh-cut products cannot be managed to offer such afavourable condition during the acquisition phase. In addition,Giovenzana et al. (2014) applied Vis/NIR and NIR spectroscopy tomeasure the quality of fresh-cut leaves of Valerianella throughpackaging, throughout the cold storage. In this case, the packagingwas used to envelop the probe (a sensing optical-fiber with a ring oflighting optical fibers). The relative geometry among light, plasticsurface and sensor was set and induced only a fixed attenuation onthe hyperspectral measures (whose amount at each wavelengthwas dependent on the optical properties of the plastic material). Inthat paper, all the hyperspectral data were acquired by placing theprobe in contact with the leaves
