Ball milling was used for producing complex arabinoxylan oligosaccharides (AXOS) and low molecular mass arabinoxylans (AX) from wheat bran, pericarp-enriched wheat bran, and psyllium seed husk. The arabinose to xylose ratio of the samples produced varied between 0.14 and 0.92, and their average degree of polymerization (avDP) ranged between 42 and 300. Their fermentation for 48 h in an in

Inulin-type fructans (ITF) and arabinoxylan oligosaccharides (AXOS) are broken down to different extents by various bifidobacterial strains present in the human colon. To date, phenotypic heterogeneity in the consumption of these complex oligosaccharides at the strain level remains poorly studied. To examine mechanistic variations in ITF and AXOS 2013-09-01 · Arabinoxylan-oligosaccharides (AXOS) represent a new class of candidate prebiotics. They are fragmentation products of arabinoxylans (AX), which occur in the cell wall of many cereal grains, consisting of a main chain of beta-1,4-linked D-xylopyranosyl units to which O-2 and/or O-3-L-arabinofuranosyl units are linked , , . A concise synthetic strategy has been developed for assembling densely substituted arabinoxylan oligosaccharides, which are valuable substrates for characterizing hemicellulose-degrading enzymes. The xylan backbone has been prepared by an iterative preactivation-based glycosylation approach with phenyl thioglycosides.

Arabinoxylan oligosaccharides

2007-02-01 · Arabinoxylans (AX) are the main non-starch polysaccharides found in many cereal grains and are part of dietary fibre. They consist of β- (1,4)-linked d -xylopyranosyl residues to which arabinofuranosyl moieties are attached. They are degraded in the colon by specific intestinal bacteria possessing AX-degrading enzymes. Oligosaccharides can have many functions including cell recognition and cell binding. For example, glycolipids have an important role in the immune response. They are normally present as glycans : oligosaccharide chains linked to lipids or to compatible amino acid side chains in proteins , by N - or O - glycosidic bonds . Arabinoxylan oligosaccharides (AXOS) are considered as DF with prebiotic potential, but so far no studies have investigated their metabolic effects in humans.

Arabinoxylan oligosaccharides (AXOS) are prebiotic carbohydrates with promising health-promoting properties that stimulate the activity of specific colon bacteria, in particular bifidobacteria. However, the mechanisms by which bifidobacterial strains break down these compounds in the colon is still unknown.

Objectives: We assessed whether wheat bran extract (WBE) containing arabinoxylan-oligosaccharides (AXOS) elicited a prebiotic effect and modulated gastrointestinal (GI) parameters in healthy preadolescent children upon consumption in a beverage.

2012-02-01 · Ball milling was used for producing complex arabinoxylan oligosaccharides (AXOS) and low molecular mass arabinoxylans (AX) from wheat bran, pericarp-enriched wheat bran, and psyllium seed husk. The arabinose to xylose ratio of the samples produced varied between 0.14 and 0.92, and their average degree of polymerization (avDP) ranged between 42 and 300. Arabinoxylans (AX) from cereals are cell wall components that constitute an important part of the dietary fiber intake in humans. Enzymatic hydrolysis of AX yields arabinoxylan-oligosaccharides (AXOS), consisting of arabinoxylooligosaccharides and xylooligosaccharides (XOS).

2018-03-07 · OBJECTIVE AND DESIGN: The aim of this study was to determine the corrective effects of wheat bran-derived arabinoxylan oligosaccharides in obese mice fed a western diet (WD). WD was given for 4 weeks before wheat bran extract (WBE) supplementation (5%) for an additional 4 weeks, whereas a control group received the standard diet. 2015-04-30 · A procedure for the production of A 3 X by hydrolysis of wheat flour arabinoxylan by a GH family 10 endo-1,4-β-xylanase from Aspergillus aculeatus was more recently described by Rantanen et al. 19 (Note: nomenclature rules are based on procedures described for α-gluco-oligosaccharides, 20 galactomanno-oligosaccharides, 21 xylogluco-oligosaccharides 22 and arabino-xylo-oligosaccharides 23). The aim was to study arabinoxylan-oligosaccharide production from rye bran using heat pretreatment and enzymatic hydrolysis. Due to the potential application in foods, the purity of arabinoxylan was also assessed.
