Abstract: The characteristic and kinetics of free radical decay in irradiated starch from sweet potato have been investigated by ESR at room temperature. It is found that the relative concentration of free radical is related to the dose. The decay follows second order kinetics at room temperature. The constant of decav and half life of free radical have been obtained.

Key words: Starch free radical, ESR, Kinetics of free-radical decay
