Aqueous solutions (4%) of glucose, fructose, and sucrose were exposed to gamma irradiation in the dose range of 2.2 to 24.0 megarads. The <tex-math>$G_{\text{glyoxal}}$</tex-math> values at 2.2 megarads were 0.35, 0.18, and 0.06 for glucose, fructose, and sucrose, respectively. These values decreased at higher dose levels. The glyoxal concentration of the irradiated solutions did not appreciably change during a 2-week postirradiation storage at room temperature.
