NON-STARCH POLYSACCHARIDE HYDROLYSING ENZYMES

摘要

The invention pertains to enzymes having xylan-degrading activity, obtainable by extraction of wheat flour, which enzymes have an apparent molecular weight between 25,000 and 68,000 Da. The enzymes have two types of endo-xylanase, beta -xylosidase and arabinofuranosidase activites. The enzymes can be obtained by extracting wheat flour using an aqueous solvent and selectively precipitating proteinaceous material from the extract obtained or from a fraction thereof, and optionally further fractionating the precipitate.
