Abstract

The objective of this research was to compare the optical properties of some citrus fruits (orange, mandarin and lemon) before and after cold storage over the visible and near-infrared wave region (400–1000 nm). AvaSpec-2048 Standard Fiber Optic Spectrometer was used to acquire spatially resolved diffuse reflectance images from the samples of orange, mandarin and lemon. Seven effective wavelengths (480, 535, 675, 720, 840, 880, 978 nm) were selected to realize hyper-spectral tests. The obtained results show that for flesh and skin of fruits after cold storage, there was not any peak at 675 nm excluding orange skin, this attribute after cold storage fruits become over ripe that there was not chlorophyll content as before storage; cold storage had not any effect on chlorophyll content of orange skin. Results also show that
