Abstract: This invention relates to the isolation and purification of nutritional supplements and prebiotics, such as xylo-oligosaccharides, and specifically the removal of color bodies, said xylo-oligosaccharides sourced from from ligno-cellulosic feedstocks such as sugar cane and sugar cane bagasse. Removal of color bodies provides greater purity in certain xylo-oligosaccharides as described. This process can also be applied to non-sugar cane feedstocks such as agricultural residues (wheat straw, corn stover, rice straw, etc.), purpose grown crops including but not limited to sugar cane, sorghum, Miscanthus, and woody biomass such as poplar.

Abstract: This disclosure relates to the co-production and co-delivery of a pre- and postbiotic and antioxidant that are chemically linked and thus can be delivered as a single product instead of a blend of individual molecules. This xylooligosaccharide (XOS) product is used as a nutritional supplement and/or food ingredient that improves digestive health and overall wellness.
