Description: Microbiological safety of fruit nectars is commonly assessed regarding the total mesophilic counting, molds and yeasts population, salmonella detection, total and fecal coliforms and specific pathogenic strains such as Escherichia. coli O157:H7. However, thermal resistant molds may also be of concern considering their potential to produce mycotoxins such as patulin. This study aimed at characterizing the thermal inactivation kinetics of the most thermal resistant mold isolated from an aseptically packaged fruit nectars industrial line and its potential to produce patulin in different nectars (mango, pineapple and passion fruit). Ascoposores suspension of each mold isolate faced an increasing intensity thermal shocks in order to select the most thermal resistant one, which was further inoculated and activated in each nectar. The following kinetic parameters resulted from the study for mango, passion fruit and pineapple nectars, respectively: z values: 4.0
