The effects of daily administration the galactooligosaccharides (GOS ; 1 or 3g) for three weeks on fecal microflora, pH, moisture, enzyme activity, putrefactive substances and volatile fatty acids (VFA) were studied during the test period in eight healthy adult men (ages 26-57 years). The number of fecal Bifdobacterium significantly increased (p<0.01) by the 1g-GOS intake. Fecal ?A-glucuronidase and ?A-glucosidase activities significantly decreased (p<0.05) by the 1g-GOS intake. The concentration of fecal ammonia (p<0.01), phenol (p<0.05), p-cresol (p<0.01), indole (p<0.05), isobutyric acid (p<0.01) and isovaleric acid (p<0.05) significantly decreased by the 3g-GOS intake.
