Sugars Formed During Irradiation of Maize Starch. Identification and Determination Sugars of low molecular weight formed during irradiation of maize starch were identified and determined by ion exchanger chromotography. The following sugars were found: one disaccharide (maltose), hexoses (glucose, mannose, galactose, fructose), pentoses (arabinose, xylose, ribose), and one tetrose (erythrose). There remains a slight uncertainty in the cases of mannose and erythrose. The influence of irradation conditions (dosis, atmosphere, temperature), of starch properties (bumidity, impurities, glucosidic bonds), and of storage conditions was examined. By the results it was made possible to propose a hypothesis on the kind of sugar formation and on the role of water in this process, which takes the observed differences into consideration satisfactorily. Irradiation effects have been compared to those given by heating.
