  • Applications

    endo-1,4-beta-Xylanase II (CAS 140222-29-3) is an industrial biocatalyst enzyme that hydrolyzes xylan-containing polysaccharides. In pulp and paper processing, it supports biobleaching and improves fiber-processing efficiency. In animal feed, it enhances digestibility by breaking down arabinoxylans in cereal-based diets. In food processing, it can improve dough handling and bread crumb structure, and it is used to clarify plant-based juices by reducing viscosity through xylan degradation. In textiles, it is used for bio-polishing of cotton fabrics to improve softness and brightness. In detergents and household-cleaning formulations, it aids soil removal from plant-based soils by breaking down xylans. Its use is subject to local regulations and formulation limits.
