The objective of the present study was to evaluate the use of hand-held near infrared spectroscopy to monitor the quality of tomatoes grown in greenhouse. The soluble solids content (TMS), total acidity (TA) and color settings were followed from fruit set until harvest at full maturity. This monitoring was conducted during the Spring and Summer. The spectral data and quality have been used to construct chemometric models in order to (1) monitor the fruit according to their stage of development and (2) predict fruit quality. The discriminant models have traced the chronological evolution of fruit and mark the entry in the maturation stage. Quantitative models (PLS) were used to predict the TMS, TA and fruit color considering the season and the fruit maturity stage.
