Before irradiation, sage tea samples exhibit one asymmetric singlet ESR signal centered at g=2.0037. Beside this central signal, two weak satellite signals situated about 3 mT left and right to it in radiation-induced spectra. Irradiation with increasing doses caused a significant increase in radiation-induced ESR signal intensity at g=2.0265 (the left satellite signal) and this increase was found to be explained by a polynomial varying function. The stability of that radiation-induced ESR signal at room temperature was studied over a storage period of 9 months. Also, the kinetic of signal at g = 2.0265 was studied in detail over a temperature range of 313-353 K by annealing samples at different temperature for various times.enginfo:eu-repo/semantics/openAccessElektron spin rezonansı (ESR)Sage teaAda çayıIrradiationIşınlamaFood irradiationGıda ışınlamasıKineticsKinetikCelluloseSelülozAnnealingTavlamaElectron spin resonance (ESR)article795405444
