The objectives of this work were to determine carbohydrate composition and in vitro digestibility of DM and nonstarch polysaccharides (NSP) in corn, wheat, and sorghum and coproducts from these grains. In the initial part of this work, the carbohydrate composition of 12 feed ingredients was determined. The 12 ingredients included 3 grains (corn, sorghum, and wheat), 3 coproducts from the dry gr...

The oxidative gelation of maize bran arabinoxylans (MBAX) using a peroxidase/H(2)O(2) system as a free radical-generating agent was investigated. The peroxidase/H(2)O(2) system led to the formation of dimers and trimer of ferulic acid as covalent cross-link structures in the MBAX network. MBAX gels at 4% (w/v) presented a storage modulus of 180 Pa. The structural parameters of MBAX gels were ca...

The paper analyzes the literature on therapeutic and prophylactic effects of components secondary products processing rye wheat – dietary fiber phenolic compounds human health. A special role is played by soluble arabinoxylans xylooligosaccharides associated with ferulic acid, which have prebiotic, antioxidant immunomodulatory properties. Experimental epidemiological studies shown that inclusio...

Ball-milled alcohol-insoluble residue (AIR) was prepared from switchgrass (Panicum virgatum var Alamo) and sequentially extracted with 50 mM ammonium oxalate buffer, 50 mM sodium carbonate, 1 M KOH containing 1% NaBH(4), and 4 M KOH containing 1% NaBH(4). Arabinoxylan was the most abundant component of the 1 M KOH-extracted fraction, which was treated with endoxylanase to generate oligosacchari...

Arabinoxylans (AXs) – non-starch polysaccharides (NSPs) is one of the most discussed main components contained in all parts cereal plants. AXs combine bioactive and technological functions. As dietary fibres, they have physiologically beneficial properties for human health. are water-soluble insoluble water. The structure, quantity depend on which part grain or plant extracted method isolation ...

Xylanase is an enzyme that catalyzes the hydrolysis of 1,4-beta-D-xylosidic linkages in xylans that are constituents of hemicellulose, a structural component of plant cell walls. Arabinoxylans (also known as pentosans) are highly branched xylans that occur in wheat and rye flour. Several xylanases from fungal and bacterial sources are currently marketed for use in baking (Amfep; Pariza and John...
