Abstract: This paper studied the crystallization properties of the lotus root’s native starch and different storage changes during and after gelatinization. Results showed that the crystal structure of the lotus root starch is B type, while that of amylase is V type and amylopectin shows no crystal structure. The crystal collapses during gelatinization. However, tiny crystals appear when gelatinization goes on. Lotus root starch paste and gel become steady during storage but the crystallization (eve) slightly increases.

Key words: lotus root starch, gelatinization, crystallization
