STABILITY OF CELLULOSE RADICALS PRODUCED BY RADIATION IN SPICES AS STUDIED BY THE EPR SPECTROSCOPY

Katarzyna Lehner, Waclaw Stachowicz


The results are presented of EPR measurements on the stability of cellulose radicals produced in 26 popular spices irradiated with a dose of 7 kGy of gamma rays.
Epr measurements were done with the use of an EPR spectrometer EPR-10 MINI at X band (microwave radiation of frequency 9.5 GHz), produced by St. Petersburg Instruments Ltd.
The aim of the work was to prove the applicability of the epr method for the control of irradiation in the investigated spices.
