Structure of In Vitro Digestion Residues from High-Amylose Starch Impacts Colonic Microbial Composition and Metabolic Activity.
Resistant starch (RS) is a nondigestible carbohydrate that serves as a prebiotic and is fermented by colonic bacteria to produce short-chain fatty acids (SCFAs). Here, in vitro digestion-derived residues (RSs) from five high-amylose starches (HASs; four RS2 and one RS3) were evaluated for their effects on microbiota co...
