Nature of radicals resulting from γ-irradiation of starch and maltose
Description
ESR and gas chromatography methods are used to study starch and maltose radiolysis products, their radiochemical yields are determined. Irradiation was carried out at 60Co γ-source in sealed ampoules in air media at 77 K, the dose rate being 45 kGy/h. It is shown that radiochemical transformations are followed by decomposition of pyranose cycle. Radiation effect on starch results mainly in formation of the end macroradicals with unpaired electron localization in C-1 and C-4 positions
