Researchers at the University of California, Davis have developed alacto-oligosaccharide (GOS) formulations selectively promote growth of beneficial Bifidobacteria species by tailoring oligosaccharide chain lengths.
This technology provides specialized galacto-oligosaccharide (GOS) compositions enriched for specific degrees of polymerization (DP) that preferentially stimulate growth of target Bifidobacterium species in the gastrointestinal tract. By adjusting the distribution of oligosaccharide chain lengths (e.g., DP3, DP4-5, DP6-8) and reducing undesired mono- and disaccharides, these purified GOS preparations enhance colonization of beneficial gut bacteria such as B. breve, B. longum subspecies infantis and longum, and B. adolescentis. The compositions can be incorporated into diverse food and dietary supplement products, including infant formula, follow-on formula, toddler beverages, and probiotics, thereby supporting gut health, immunity, and potentially alleviating gastrointestinal disorders.
