Hemicellulase Pentosans or hemicelluloses are long-chained carbohydrate molecules that are naturally present in flour.
Furfural formation from raw material containing pentosans consists of two steps, the first step involves acid--catalysed hydrolysis, where the pentoses chain are hydrolysed at high temperatures to monomeric pentose in aqueous media [9].
The investigators examined the effect of adding water-soluble pentosans (WSP) and water-insoluble pentosans (WUS) together with GOX.

The wastewater contains fiber, small amounts of starch and protein, and gums called pentosans.
The relationships of DE, ME, and ATTD of various chemical constituents in wheat with small particle size might be due to the disruption of the aleurone layer, which consists of pentosans and cannot be broken down by monogastric animals, thus making inaccessible nutrients available for digestion [8,21].
Wall constituents are characterised by the presence of pentosans that are able to absorb water 20 to 50 times their weight.
A rapid first stage was noted as easily hydrolyzed substances, mostly pentosans, were removed by formation of organic acids, causing a reduction of the solution's pH value.
The two types of pentosans found in cereals are soluble and insoluble.
The research conducted at Penn State on Kenaf Core, a by-product of a hemp plant used in fiber production, served as an example of the importance of Pentosans, an important carbohydrate found in corn cobs, sought out by chemical companies, but important for mushroom nutrition.
Damaged starch and pentosans increase flour water absorption, which decreases soft wheat quality for most pastry products.
