High throughput FT-MIR indirect analysis of sugars and acids in watermelon.Indirect measurements of taste-related compounds are required when a high number of samples has to be analyzed in a short period of time, with a minimum cost.  For this purpose, FT-MIR partial least square (PLS) regression models for the prediction of total soluble solids, sugars and organic acids have been developed using three sample sets including breeding lines and commercial varieties of watermelon.  The robustness of FT-MIR models was assessed with predictions of external assays, obtaining reasonable performances.
