Hemicellulase from Aspergillus niger is widely used in the food industry to improve the texture and digestibility of plant-based foods. It helps break down hemicellulose in grains, making it easier to extract sugars and enhance fermentation processes, such as in brewing and baking. In the production of fruit juices, it aids in clarifying the liquid by breaking down complex polysaccharides, resulting in a clearer and more stable product. Additionally, it is employed in animal feed to improve nutrient absorption by breaking down fibrous components, enhancing the overall digestibility and nutritional value of the feed. In the biofuel industry, it plays a role in the breakdown of biomass, facilitating the conversion of plant materials into biofuels. Its application in the paper and pulp industry helps in the efficient processing of raw materials, reducing energy consumption and improving the quality of the final product.
