| Abstract: | In this paper the method of determining the absolute crystallinity of starch from an X_ray diffraction pattern is studied. It is shown that the absolute crystallinity of starch and the proportion between the microcrystal and the submicrocrystal can be determined according to an X_ray diffraction pattern after the pattern has been accurately divided into the three areas of submicrocrystal area, microcrystal area and amorphous part. The results of this method agree well with literature values. |
