In vitro digestibility and colonic fermentability of aleurone isolated from wheat bran

Recombinant Xylanase from Bacillus tequilensis BT21: Biochemical Characterization and Its Application in Production of Xylobiose from Agricultural Residues

“…A lignocellulosic material wheat bran, which is a by-product of conventional wheat milling, is available in large quantities (43) and a good source of raw material for xylooligosaccharide production. Enzymatic hydrolysis by xylanase from B. tequilensis BT21 on wheat bran released xylobiose and xylose.…”

Temporal and spatial changes in cell wall composition in developing grains of wheat cv. Hereward

“…Insoluble dietary fibres are effective faecal bulking agents, decreasing transit time and binding carcinogens (Moore et al 1998), and both soluble and insoluble fibre are fermented to a variable extent by the large bowel microflora with beneficial effects on human physiology (Topping 2007). Soluble fibre is more readily fermented but depending on its structure, insoluble fibre, and especially AX from the endosperm and aleurone layer, may also be degraded by gut microflora (Amrein et al 2003;van Laar et al 2000). This leads to increases in beneficial colon microbes, the production of short chain fatty acids, decreased colonic pH and reduced absorption of cholesterol and glucose (Moore et al 1998;Lewis and Heaton 1999).…”

Immunomodulatory properties of two wheat bran fractions – aleurone-enriched and crude fractions – in obese mice fed a high fat diet

“…Bran, which is composed of 50% pericarp/testa and 50% aleurone layer, is particularly rich in dietary fibers (50% of the bran weight) [2,22]. The pericarp testa is constituted of lignified cell walls, where cellulose microfibrils are dispersed in acidic arabinoxylans (AX) [2].…”
