Utilization of Pancreatin-indigestible Parts of Modified Starch by Various Intestinal Bacteria

Abstract

The utilization of pancreatin-indigestible parts of several kinds of modified starch by various intestinal bacteria in vitro was investigated. Four kinds of hydroxypropyl distarch phosphate (HP) and two kinds of oxidized starch (PO) with different degrees of substitution prepared from potato or corn starch were used as the modified starch. HP and PO were slightly utilized by Bifidobacterium spp., except for B. bifidium, B. infantis and B. longum. PO was utilized more readily than HP. In general, the modified starches used in this study were difficult for intestinal bacteria to utilized.
