Effects of wheat bran extract rich in arabinoxylan

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. (A) Molecular structures of the different AX oligosaccharides used in the experiments. 3 3 -a-L Although some health effects of AX are documented, the effects of their hydrolysis products, the arabinoxylan oligosaccharides (AXOS), are less studied.

Colourimetric oligosaccharides with a chemically-defined structure are available for the measurement of the activity Abstract. Wheat bran extract (WBE) is a food-grade soluble fibre preparation that is highly enriched in arabinoxylan oligosaccharides. In this placebo-controlled Prebiotic effect of Arabinoxylans and Arabinoxylan-Oligosaccharides and the relationship with good health promotion.

Two pure xylanases namely RmXyn10A from GH family 10 and 3 apr. 2020 — Arabinoxylan oligosaccharides (AXOS) are a prebiotic product that advantageously affect the activity and composition of the gut bacteria. Arabinoxylan oligosaccharides (AXOS) are considered as DF with prebiotic potential, but so far no studies have investigated their metabolic effects in humans.

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. While the (A)XOS metabolism of Bifidobacteriaceaehas been extensively studied, information regarding lactic acid bacteria (LAB) is still limited in this context. Upon hydrolysis of arabinoxylans by enzymes, arabinoxylan oligosaccharides are produced. Many gut microbes are capable of degrading arabinoxylans, such as lactobacilli, Bacteroides, Roseburia eubacterium, Faecalibacterium prausnitzii, Bi. animalis, and nonpathogenic clostridia (Grootaert et al., 2009).

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 2013-11-01 The arabinoxylan oligosaccharides are excellent tools to map the active site of glycosyl hydrolases involved in xylan deconstruction. The substrate specificities of several xylanases and arabinofuranosidases were determined by analyzing the digestion products after incubation of the oligosaccharides with glycosyl hydrolases. 2015-07-14 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.

Aim of the study To test the effect of AXOS in a rat colon carcinogenesis model. Arabinoxylan-oligosaccharides (AXOS) are produced by partial enzymic hydrolysis of the cereal fibre arabinoxylan (AX) and have recently been proposed as a new prebiotic substrate (Reference Grootaert, Delcour and Courtin 1).To classify a food component as a prebiotic, it needs to fulfil three criteria (Reference Gibson, Probert and Van Loo 2).. The first criterion is resistance to gastric acid Herein, a chemoenzymatic approach to artificial arabinoxylan polysaccharides with systematically altered branching patterns is described. The polysaccharides were obtained by glycosynthase‐catalyzed polymerization of glycosyl fluorides derived from arabinoxylan oligosaccharides.

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.
