Abstract

This study investigated whether the crystalline structure of the retrograded starch affects the contents of slowly digestible starch SDS and resistant starch RS When the relative crystallinities were similar there was no difference in RS content between the retrograded starches with A and Btype crystallites However the SDS content in Atype crystalline structure was constantly higher than Btype contradicting the observation that the granular starches with Btype crystallites were more enzyme resistant Therefore the primary factor that accounts for the digestibility of granular starch is not the crystalline structure but the granular properties including the surface pores and the size
