During gel treatment with amylolytic enzymes,
the amorphous fraction undergoes hydrolysis and further
ordering of amylose chains proceeds, contrary to the crystalline
fraction built of those chains, which remains resistant
to the enzymatic activity [Colquhoun et al., 1995]. The formation
of resistant starch III is affected by lipid substances
which occur in starch of numerous plants and form inclusive
complexes with amylose, penetrating into its chains. Such
amylose does not bind into double helices which form crystalline
structures upon aggregation. Therefore, a lower
number of insoluble crystallites of amylose are precipitated
in the retrogradation process, thus less resistant starch is
produced
