By electron spin resonance (ESR) spectroscopy, we revealed free radicals in irradiated foods. The representative ESR spectrum of irradiated food is composed of a sextet centered at g = 2.0, singlet at the same g-value and a singlet at g = 4.0. The first signal is attributable to a signal with hyperfine interactions of the Mn $^{2+}$ . The second signal is due to organic free radicals. The third signal may be originated from the Fe $^{3+}$ . Upon -irradiation, new signals appeared. For the measure of irradiation effects, we proposed an advanced protocol for ESR detection of irradiated foods.
