Abstract: By gel permeation chromatography (GPC),it was found that microwave irradiation causes serious degradation of starch molecules in short time. Proper degradation is beneficial to the formation of resistant starch (RS). At different water contents,the extents of degradation are different. For example,at 85% water content the extent is the most serious but at 45% water content the extent is the most slight. 75% water content is the most suitable and the maximum yield of RS is achieved.

Key words: microwave, resistant starch
