Effect of apple pectin oligosaccharide on intestinal disorders

Abstract

Apple pectin oligosaccharide (APO) prepared from apple juice residue contained about 30% uronic acid, the principal component of pectin. We found that APO is utilized by major species of human intestinal microflora, such as Bacteroides sp. and Bifidobacterium sp., and that it induces the production of short-chain fatty acids, mainly acetic acid and butyric acid. Moreover, APO was observed to reduce fecal putrefaction by fecal batch culture test. Since APO is expected to be effective for improving intestinal function, APO (5 g/day) was administrated for 2 weeks to 7 subjects who tended to be constipated. Intake of APO led to an increase in bowel movement frequency and improved fecal condition, including fecal odor. Thus, APO intake may contribute to improving intestinal disorders.
