Description

Pullulanase is a highly specific debranching enzyme that catalyzes the hydrolysis of α-1,6-glycosidic linkages in polysaccharides like pullulan and amylopectin. This specificity makes it a critical biocatalyst for enhancing the efficiency and yield of starch conversion processes. It is an essential component for producers in the food, beverage, and biofuel industries seeking to optimize saccharification and improve product quality.

Application

• Starch Saccharification: Used in combination with glucoamylase to produce high-glucose and high-maltose syrups by efficiently hydrolyzing the branch points in amylopectin.
• Brewing & Distilling: Enhances fermentation efficiency by increasing fermentable sugar yield, leading to higher alcohol content and improved process economics.
• Baking: Improves dough handling, bread volume, and crumb texture by modifying starch during the baking process.
• Sugar Syrup Production: Critical for manufacturing maltotriose syrup and other specialized sugar syrups with defined carbohydrate profiles.
• Bioethanol Production: Increases the yield of fermentable sugars from starch-based feedstocks like corn and grains, boosting biofuel output.
• Textile Desizing: Assists in the removal of starch-based sizing agents from fabrics in an efficient and specific manner.
