Abstract

European standards EN1787 and EN13708 specify spectroscopic methods for the detection of irradiated food. Electron spin resonance (ESR) spectral characteristics of radiation-induced radicals in standard marker materials (cellulose, glucose, fructose, and saccharose) were compared. Standard marker materials were gamma-irradiated (0 and 10 kGy) and mixed at different blending ratios (0–100 %) to evaluate their sensitivity upon ESR detection. Blended samples produced specific ESR signals which showed increased intensities by an increasing percentage of the irradiated component. However, detection was possible with 30 % irradiated component. The results could be helpful in interpreting complex ESR signals in plant materials containing cellulose and sugar materials.
