software, native lotus seed starch exhibited a C-type crystalline pattern with characteristics of the A- and B-type crystalline pattern, four strong peaks at 17.63, 19.72, 21.11, and 26.91
2h, and two broad peaks at 25.49 and 28.20 2h. The degree of crystallinity is a useful indicator of the properties of starch and starch-containing products. Lotus seed resistant starch had a Btype crystalline pattern with more intense diffraction peaks at 19.99 2h than were observed for native starch. Moreover, LRS showed doublet peaks between 25.60 and 27.94, with the peak
near 17.43 disappearing and becoming the dispersion peak with characteristics similar to those of the sub-crystal structure
