Old Mike has researched this and here are some of the links he found. But for me what is most important is what I see with my own eyes, and maltodextrin has caused problems for me more than once. That said perhaps it will not be as bad for you since everyone is different.
https://www.ncbi.nlm.nih.gov/pmc/articles/pmc4133521/Maltodextrin, a polysaccharide derived from starch hydrolysis that is used as food additive, has been shown to markedly enhance AIEC biofilm formation and adhesion to intestinal epithelial cells and macrophages. Maltodextrin favors type 1 pili expression, which is required for biofilm formation and adhesion.
