Abstract In this study, the usefulness of different mathematical models to predict the retention of ascorbic acid (AA), total phenols (TP) and DPPH radical scavenging activity (SA) of pasteurized pineapple juices during storage has been evaluated. The results indicate that first-order kinetic model provided the best prediction of the degradation of AA (MAE = 0.0059; MRE = 0.0117; MSE = 0.0001; R 2  = 0.9995) whereas Weibull model provided the less satisfactory prediction (MAE = 0.2387; MRE = 0… CONTINUE READING
