Abstract : Dry matter and a maturity index defined as a function of TSS were linearly correlated with hue and chroma colour values of 125 and 150 mangoes, respectively taken by the Hunter Lab colorimeter and the predicted maturity index was validated with another set of same number of samples and through sensory evaluation. The performance of the developed models was tested, based on standard error of calibration (SEC), standard error of prediction (SEP), and multiple correlation coefficients (R). The SEC, SEP and R of the model based on maturity index were found to be 12.91%, 12.20%, and 0.91, respectively, while they were found to be poor for dry matter content. The sensory test also showed agreements between predicted maturity index and taste after ripening, which indicated that maturity of mango fruits could be predicted by measuring colour using a colorimeter.
