“…14 Previously, something similar was shown for the fermentability of isomalto/maltopolysaccharides (IMMPs), 60 a soluble starch-based dietary fibre, that consist of a long chain of linearly linked α-1,6 glucose residues, connected to a short α-1,4 linked glucose chain. 61,62 In vitro fermentation of these IMMPs, with and without the presence of the α-1,4 linked fraction showed that the microbiota favoured to ferment the α-1,4 linked fraction (i.e. the digestible fraction) over the α-1,6 linked fraction, while once the α-1,4 linked fraction was depleted, the microbiota could not ferment the α-1,6 linked fraction anymore.…”
