The effects of biotechnically synthesized oligosaccharides and polydextrose on defecation and putrefactive metabolites in human beings were investigated. Fifty young volunteers were divided into five groups, with ten subjects in each group. All subjects were on their normal diet but with a relatively restricted amount of dietary fiber for 18 days. During the period, 10 g/day of either fructooligosaccharide-1, fructooligosaccharide-2, isomatooligosacchride, galactooligosaccharide or polydextrose was given to each subject of each group. The fecal putrefactive metabolites (indole and p-cresol) were determined by gas chromatography. The defecation status was recorded 14 days before the experiment commenced and fill to the end of the experiment. Results showed that p-cresol content was reduced (p<0.05) in isomaltooligosaccharide, galactooligosaccharide and polydextrose indigested fed groups. Isomaltooligosaccharide fed group had significantly (p<0.05) lower indole content. Constipation condition was improved in all five groups.
