Abstract
Mixes of sucrose and various proportions of ascorbic acid were irradiated with γ-rays and studied by an electron paramagnetic resonance (EPR) spectroscopy. Before irradiation no EPR signals have been recorded. After irradiation an EPR spectrum of sucrose has been observed from all samples independently of the quantity of ascorbic acid. The influence of the microwave power and the modulation amplitude on the EPR intensity was reported. It has been found that the EPR signal intensity of sucrose decreased when the ascorbic acid is added to it. This result suggests that ascorbic acid play role of free radical scavenger because of its antiradical activity.
