2009-09-19 · Feruloylated arabinoxylans are the major non-starch polysaccharides from the cereal cell walls. Depending on the source, arabinoxylans exhibit different molecular features, which are determinants for their functional properties. Feruloylated arabinoxylans are of considerable importance in cereal process such as bread making and brewing.
Arabinoxylans consist of a linear chain backbone of ß- d -xylopyranosyl (Xyl p) residues linked through (1 → 4) glycosidic linkages. α - l -Arabinofuranosyl (Ara f) residues are attached to some of the Xyl p residues at O-3, O-4, and/or at both O-2,3 positions, resulting in four structural elements in the molecular structure of arabinoxylans: monosubstituted Xyl p at O-2 or O-3, disubstituted Xyl p at O-2,3, and unsubstituted Xyl p (Fig. 2).

Recent attention to dietary fiber in wheat (Triticum aestivum L.) has invigorated research in the nonstarch carbohydrate arabinoxylan (AX). AX molecules are composed of a linear xylose backbone with arabinose substitutions along the backbone. These arabinose substituents can also carry a ferulic acid moiety.

Cereal Also, the changes in arabinoxylan structures during malting and brewing 16 May 2017 Rye arabinoxylans (AXs) might be used as baking improvers for In wheat bread, the main structure-forming component which gives the enzyme digests, a structural model is proposed for the arabinoxylans. This model saccharides from alkali-extractable wheat flour arabinoxylan.
Arabinoxylan chains contain a large number of 1,4-linked xylose units. The structure of arabinoxylans consists of a backbone of β-(1,4)-linked xylose residues, which are substituted with arabinose residues on the C(O)-2 and/or C(O)-3 position (Dornez et al., 2009) (Fig. 11.2A).

In this manuscript are reviewed the chemical structure, sources and applications of feruloylated arabinoxylans and arabinoxylan gels. Feruloylated arabinoxylans are the major non-starch polysaccharides from the cereal cell walls. Human fecal fermentation profiles of maize, rice, and wheat bran and their dietary fiber fractions released by alkaline-hydrogen peroxide treatment (principally arabinoxylan) were obtained with the aim of identifying and characterizing fractions associated with high production of short chain fatty acids and a linear fermentation profile for possible application as a slowly fermentable dietary 2012-01-31 Wheat Arabinoxylan Structure Provides Insight into Function Alecia M.

Results showed that H and D stress decreased the TKW, the β-glucan contents of the seeds Fifty bread wheat (Triticum aestivum L.) cultivars were selected from the HEALTHGRAIN germplasm collection based on variation in their contents of total and water-extractable arabinoxylan. FT-IR spectroscopic mapping of thin transverse sections of grain showed variation in cell wall arabinoxylan composition between the cultivars, from consisting almost entirely of low-substituted arabinoxylan 2017-06-14 arabinoxylan structure but is not alone capable of catalyzing complete hydrolysis. Auxiliary enzyme activities that catalyse the hydrolysis of various substitutions are also necessary and several of such enzymes are investigated.

O’Neill1 1Complex Carbohydrate Research Center and US Department of Energy BioEnergy Science Center, 2Department of Plant Biology, and 3Department of Biochemistry and Molecular Biology, 2018-08-11 This study investigated the effects of water-extractable arabinoxylan (WEAX) on gluten by thermal treatment. Fourier transform infrared spectroscopy (FTIR) results showed that heating significantly decreased β-sheets and β-turn structures in gluten proteins between 25 and 55 °C. The addition of WEAX caused a transition from β-turn to β-sheets at >55 °C.
