Neosartorya fischeri is a heat resistant fungi able to grow in fruit juice and a potential mycotoxins and pectinolytic enzymes producer. The temperature is one of the most important factors affecting the fungal growth kinetics during food distribution and storage. The objective of this study was predicting N. fischeri growth under non-isothermal conditions and validating the predictions with experimental data. The growth curves of N. fischeri were described by the Baranyi and Roberts model, and the dependence of the model parameters with the temperature was described with the square root and logarithmic models. The prediction of N. fischeri growth was performed for two different non-isothermal profiles. In the first profile, temperature changed between 10 and 20 ºC, every 24 hours; in the second profile temperature of incubation changed from 20 ºC to 30 °C after 170 hours, keeping this temperature until the fungal diameter reached the entire plate. The results showed that the mathematical model was able to predict the growth of N. fischeri for the two experiments performed, which was confirmed by the statistical indexes bias and accuracy factors, R
