The traditional chemical modified starch was mainly synthesized by chemical reaction under conventional heating conditions. The synthetic technology has such problems as long reaction time, low yield and high energy-consuming. And microwave radiation technique can cause the chemical reaction of degeneration starch was fast, high efficiency, energy saving and environmental protection. The mechanism of starch modification reactions promoted by microwave was briefly introduced. The effect of microwave radiation technology on synthetic reaction of several kinds of chemical modified starches was analyzed. It is pointed out that microwave as green synthesis technology will possess extensive application prospect in the chemical modified starch synthesis.
