Hemicellulase and cellulase are two distinct types of enzymes that play crucial roles in the breakdown of plant cell wall components. Hemicellulase, with the CAS number 9025-56-3, is a complex mixture of enzymes that target the heteropolysaccharides in plant cell walls, known as hemicelluloses. These enzymes cleave the bonds within hemicellulose chains, which are composed of various sugar units such as xylose, mannose, and others .
Cellulase, on the other hand, is a group of enzymes that break down cellulose, the main structural component of plant cell walls. It works by breaking the β-1,4-glycosidic bonds between glucose units in cellulose, which is a homopolymer . The synergistic action of endoglucanases (which cleavageβ-1,4-), exoglucanases (which remove glucose units from the ends of cellulose chains to produce cellobiose), and β-glucosidases (which convert cellobiose to glucose) is necessary for the efficient degradation of cellulose .
Both hemicellulase and cellulase are used in various food additive applications. They can improve the texture and stability of food products, as well as enhance the extraction of flavors and colors from plant materials. For instance, these enzymes can be used in the production of fruit juices, where they help to clarify the juice and improve its yield .
The use of these enzymes in food processing is generally recognized as safe, as they are derived from natural sources and have a long history of use in food production. However, like all food additives, their use is regulated to ensure safety and efficacy . They are also used in the brewing and winemaking industries to enhance the extraction of flavors and to stabilize the final product.
In terms of safety, these enzymes are produced through controlled fermentation processes and are carefully purified to ensure that they are suitable for use in food applications. They are subject to rigorous testing and quality control measures to ensure that they meet the required safety standards
