Our study is based on using a non-invasive technique, the bio-speckle technique, in order to follow the ripening of fruits during different stages: before and after the climacteric stage. To assess the impact of the ripening of fruits on their optical properties, speckle grain is measured and the variation of its dimensions is evaluated. In addition, and in order to correlate this observation with the degradation of chlorophylls, both a physical approach based on recording the fluorescence spectrum of chlorophylls, and a biochemical approach based on a pigmentation analysis, are used. We therefore show the efficiency of biospeckle metrology for monitoring fruit maturation
