The peak intensity which indicated the relative crystallinity was increased as the time for debranching (pullulanase treatment) increased up to 12 h. However, debranching for 24 h resulted in the decrease in crystallinity (peak intensity). The decrease in crystallinity when the debranching time increased from 12 h to 24 agreed with the decrease in residual stearic acid content in the complexes. Additionally, the debranching time increase resulted in the formation of new diffraction peaks at 21.5° and 23.4°, which corresponded to the crystalline pattern of stearic acid aggregates (Zhang et al., 2012).
