Resumo: With the purpose of testing the recently developed Paired Equivalent Isothermal Exposures (PETE) method, to determine reaction kinetic parameters under nonisothermal conditions, continuous pasteurizations were carried out with a nectar of a tropical fruit [25% of Cupuacu (Theobroma grandiflorum) pulp and 15% of sugar] in order to estimate the ascorbic acid thermal degradation kinetic parameters. The experimental ascorbic acid thermal degradation activation energy (96±13kJ/mol) estimated by the PETE, compared well with the previously determined value (74±5kJ/mol) for the same product under isothermal conditions. The PETE method is a reliable, easy and faster method to estimate first order reactions activation energy.
