The wiki article has some more info. This sentence does seem to indicate that the smaller glucose chains reassemble into larger starches in a crystallization process. "The glucose chains can reassociate into short crystalline structures, which typically involves rapid recrystallization of amylose molecules followed by a slow recrystallization of amylopectin molecules in a process called retrogradation." https://en.wikipedia.org/wiki/Resistant_starch https://en.wikipedia.org/wiki/Resistant_starch
