Description: The “pinhão” is the seed of Araucaria angustifolia (known as Paraná pine). This specie is in danger due to reckless exploration. Thus, the development of new applications could motivate its preservation. Samples of native “pinhão” starch were oxidized with standard NaClO solutions (0.1, 0.2 and 0.5 mol L-1) and exposed for one hour under UV light (UVC radiation with ? = 256 nm). The TG curves showed similar behavior. The oxidative modification caused a decrease in the gelatinization enthalpy (DSC).
