Starch is one of the biopolymers widely used as a raw material in various industries, its usage being based on its functional properties. Corona electrical discharges treatment is one of the newest methods among the physical methods to modify starch. Thus, the paper deals with the behavior study of some functional properties of corn starch exposed to corona electrical discharges. The apparent viscosity of corn starch increased while the solubility, gel consistency and clarity of pastes have been reduced with the increase of exposure time.
