Analysis using
NMR indicated an increase of the double helix and higher crystallinity
in the LRS relative to the other starch samples analysed.
Moreover, the results also failed to demonstrate any difference
between purified resistant starches obtained by the different
purification methods.
In addition, LRS can increase the proliferation of bifidobacteria
compared with growth in the presence of GLU or HAMS. This effect
may be related to its stable double helix structure, high crystallinity,
and rough surfaces with a scale-like or gully-like appearance.
