Abstract

The aim of the study is to summarize our investigations on combined action of microwave irradiation (2.45 GHz) and hydrogen peroxide to starch. Depending of oxidation condition (microwave power and temperature) a various products can be obtained – from slightly oxidized to deep degraded starches. Possible mechanisms of the microwave assisted processes were outlined.
