Hemicellulase

Hemicellulase is an enzyme that breaks down hemicellulose. Hemicellulose catagorizes a variety of polysaccharides that are more complex than sugars and less complex than cellulose, that are found in plant walls.

It is a mixture of enzymes which can hydrolyze the indigestible components of plant fibers. Since humans lack the endogenous enzymes required to digest plant fibers, the supplementation of hemicellulase provides humans with an additional source of nutrition and reduces the bulking effect of fibrous foods. Scientific evidence suggests that carbohydrolytic enzymes, such as Hemicellulase, can be useful supplements for digestive support and general nutritional support.

The Hemicellulase will attack on the Hemicellulose fiber to liberate smaller fragments of cellulose which is further attacked by exo-cellulase to liberate glucose.

The influence of saccharification with added hemicellulases on non-starch carbohydrates of regular rye as well as on some quality factors of mashes and stillages were examined. Laboratory experiments showed the significant influence of the type of pretreatment and hemicellulases enrichment on the dynamic of saccharification and efficiency of ethanol fermentation. It was concluded that the increase of ethanol yield as a result of hemicellulase supplementation is not connected with pentosans fermentation but with the increased availability of hexose (starch) bound with pentose chain for amylolytic enzymes. Because of the high yield of rye hybrids, this grain might be a potential source of raw materials in the distillery industry. In this research four hybrid varieties named H 1 to H 4 were tested to compare with regular variety R for their usefulness as raw material for ethanol production.
