Isolation of arabinoxylan and cellulose-rich arabinoxylan from wheat bran of different varieties and their functionalities

Food Hydrocolloids, 2021
Abstract The study evaluated the yield, emulsifying, antioxidant properties, protein content and amino acid composition of water-extractable (WE) and alkali-extractable (AE) Hemi-B and the water holding capacity and protein content of cellulose-rich arabinoxylan (CAX) fractions isolated from the bran of four wheat varieties.

Preparation and characterization of arabinoxylan esters and arabinoxylan ester/cellulose ester polymer blends

Carbohydrate Polymers, 2003
Abstract A water-soluble, high molecular weight arabinoxylan was isolated from corn fiber. This arabinoxylan was a highly branched and complex polysaccharide composed of xylose, arabinose, galactose, glucuronic acid and glucose. Treatment of this arabinoxylan with a C2–C4 aliphatic anhydride using methanesulfonic acid as a catalyst or trifluoroacetic

Arabinose content of arabinoxylans contributes to flexibility of acetylated arabinoxylan films

Journal of Applied Polymer Science, 2012
AbstractArabinoxylans (AX) from rye were partly debranched by chemical hydrolysis methods, and AXs differing in arabinosyl substitution were acetylated using chemical methods. The resulting materials are film forming, and these films underwent molecular structural analysis and were tested for their material properties.

Arabinoxylans and Arabinogalactans: A Comprehensive Treatise

Critical Reviews in Food Science and Nutrition, 2011
The functional and nutraceutical importance of various foods is often attributed to the bioactive molecules present in them. A number of components have been studied but dietary fiber and its different constituents are of prime consideration. Among these, arabinoxylan (AX) and arabinogalactan (AG) are of significant importance in that they hold ...

Solution properties of wheat-flour arabinoxylans and enzymically modified arabinoxylans

Carbohydrate Research, 1979
Abstract A series of water-soluble arabinoxylans has been prepared from purified wheat-flour arabinoxylan by partial removal of arabinosyl side-branches using an α- L -arabinofuranosidase. Their solubilities, molecular weights, intrinsic viscosities, and degrees of hydration were measured. The results suggest that the arabinoxylan assumes an extended

Arabinoxylans, gut microbiota and immunity

Carbohydrate Polymers, 2016
Arabinoxylan (AX) is a non-starch polysaccharide found in many cereal grains and is considered as a dietary fiber. Despite their general structure, there is structural heterogeneity among AX originating from different botanical sources. Furthermore, the extraction procedure and hydrolysis by xylolytic enzymes can further render differences to theses AX.

Feruloylated arabinoxylan and arabinoxylan-protein solutions do not gel upon γ-irradiation

Food Hydrocolloids, 2003
Abstract Solutions of feruloylated water-extractable arabinoxylan (WEAX) and bovine serum albumin (BSA) were γ-irradiated, separately and in admixture, at doses between 0 and 10 kGy, with the objective of gelling by radical mediated inter-chain cross-linking.

Bacterial nanocellulose‐reinforced arabinoxylan films

Journal of Applied Polymer Science, 2011
AbstractThere is an increasing interest in substituting today's films for food packaging applications with films based on renewable resources. For this purpose, rye arabinoxylans, unmodified and enzymatically debranched, were studied for the preparation of neat films and composite films reinforced with bacterial cellulose (BC).

Arabinoxylans in barley, malt and wort

1991
Abstract Arabinoxylans from barley endosperm cell walls may impair the wort preparation process. They were isolated from dehusked barley and malt, and from sweet wort. Their glycosidic linkage composition was determined, showing the presence of a large amount of C2-substituted xylopyranose.

Efficacy of supplemental multi-carbohydrases in broiler diets depends on soluble arabinoxylan-to-total arabinoxylan content

British Poultry Science, 2021
1. The objective of this study was to investigate the effect of multi-carbohydrase enzymes (MC) on net energy (NE), performance and gene expression in Cobb 500 broilers fed diets containing different levels of soluble and total arabinoxylan (sAX/tAX) ratios.2.
