Abstract:

The retrogradation mechanism of lotus root starch was studied with X-diffraction and differential scanning calorimeter. Through measuring transparency and the sedimentation rate, blue values, enzyme hydrolyzability and recrystal properties of lotus root starch paste during storage, the lotus root starch retrogradation is proved to be a result of molecular agglomeration and weak recrystallization.

Key words: lotus root, starch, retrogradation properties
