2014-09-12 · Effects of a wheat bran extract containing arabinoxylan oligosaccharides on gastrointestinal health parameters in healthy adult human volunteers: a double-blind, randomised, placebo controlled, cross-over trial. Brit J Nutr 2012;108: 2229–2242. François IEJA, Lescroart O, Veraverbeke WS, Windey K, Verbeke K, Broekaert WF. Enzymatic Polymerization of Arabinoxylan Oligosaccharides Deborah Senf,Colin Ruprecht, Saina Kishani, Aleksandar Matic,Guillermo Toriz, Paul Gatenholm, Lars W,gberg,and Fabian Pfrengle* Abstract: The heterogeneous nature of non-cellulosic poly-saccharides,such as arabinoxylan, makes it difficult to Consumption of breads containing in situ-produced arabinoxylan oligosaccharides alters gastrointestinal effects in healthy volunteers. Research output: Contribution to journal › Article The effect of feruloylated arabinoxylan mono- and oligosaccharides (FAXmo) on mammalian α-glucosidase and glucose transporters was investigated using human Caco-2 cells, rat intestinal acetone powder, and Xenopus laevis oocytes.

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 With Different DP Trigger Calcium Influxes in Arabidopsis In order to investigate whether pentose-based structures could be sensed by Arabidopsis, we decided to analyze in a first instance the capacity to trigger Ca 2+ influxes of different commercial polymeric structures ( Figure 2A ).

Prebiotic effect of Arabinoxylans and Arabinoxylan-Oligosaccharides and the relationship with good health promotion. CienciaUAT [online]. 2018, vol.13, n.1,

Helsinki 2020. Arabinoxylan-oligosaccharides (AXOS) are a recently newly discovered class of candidate prebiotics as - depending on their structure - they are fermented in different regions of gastrointestinal tract. This can have an impact on the protein/carbohydrate fermentation balance in the large intestine and, thus, affect the generation of potentially Arabinoxylan oligosaccharides (AXOS) are prebiotic carbohydrates with promising health-promoting properties that stimulate the activity of specific colon bacteria, in particular bifidobacteria.

1 Feb 2021 arabinoxylan-oligosaccharides (AXOS) are being considered as a production of wheat bran-derived arabinoxylan-oligosaccharides .

Arabinoxylan-oligosaccharides (AXOS) are a recently newly discovered class of candidate prebiotics as - depending on their structure - they are fermented in different regions of gastrointestinal tract. This can have an impact on the protein/carbohydrate fermentation balance in the large intestine and, thus, affect the generation of potentially 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. Due to their potential prebiotic properties, arabinoxylan-derived oligosaccharides [(A)XOS] are of great interest as functional food and feed ingredients.

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.

Modular assembly of oligoarabinoxylans from few building blocks was enabled by adding (2-naphthyl)methyl (Nap) to the toolbox of orthogonal protecting groups for solid Methods. A twelve-week randomized cross-over trial was conducted with two intervention periods separated by a washout period. The dietary intakes of interest were wheat bran extract, rich in arabinoxylan oligosaccharides (AXOS) (10.4 g/d AXOS) and polyunsaturated fatty acids (PUFA) (3.6 g/d n-3 PUFA). Arabinan, arabinoxylan and some other arabinose-containing polysaccharides release arabinose when hydrolyzed by T. reesei α-L-arabinofuranosidase (Roche et al., 1995). α-Galactosidase catalyses cleavage of terminal α-galactose residues from α- O -galactosides including galactose-containing oligosaccharides and branched polysaccharides, such | Pure arabinoxylan (AX) oligosaccharides trigger early immune responses in Arabidopsis.

This study investigated the potential of ball milling as a dry process for in situ production of arabinoxylan oligosaccharides (AXOS) in arabinoxylan (AX)-rich wheat and rye bran. An extensive lab-scale ball mill treatment (120 h, 50% jar volume capacity) increased the wheat bran water-extractable arabinoxylan (WE-AX) level from 4% (untreated bran) to 61% of the wheat bran AX. Extractable AX

Production of arabinoxylan-oligosaccharide mixtures of varying composition from rye bran by a combination of process conditions and type of xylanase. P Falck Xylanases were used to produce short-chain oligosaccharides from extracted arabinoxylan.

Arabinoxylans are comprised of a mixed linkage between arabinose and xylose. Arabinoxylan-oligosaccharides (AXOS) are a recently newly discovered class of candidate prebiotics as - depending on their structure - they are fermented in different regions of gastrointestinal tract.
