Abstract:The modification of waxy corn starch paste by microwave irradiation was studied. The effects of temperature, microwave power and irradiation time on the rheological property of waxy corn starch paste were investigated using a rotary viscometer. Results showed that the rheological property could be greatly affected by microwave irradiation. The treatment of microwave irradiation decreased the concentration and viscosity of the paste, changing the paste from a pseudoplastic fluid to a Newtonian fluid. This change tendency became obvious by improving the temperature and the power as well as prolonging the irradiation time.
