Description

β-Amylase CAS NO 9000-91-3 is a key exo-acting hydrolase enzyme that catalyzes the hydrolysis of α-1,4-glycosidic linkages from the non-reducing ends of starch and related polysaccharides, producing maltose. This specificity makes it an indispensable biocatalyst for controlled starch breakdown and sugar production. It is essential for manufacturers in the food, brewing, and biofuel industries seeking efficient, natural, and consistent enzymatic processes.

Application

• Starch Saccharification: Production of high-maltose syrups and maltose crystals for the food and confectionery industry.
• Brewing & Distilling: Conversion of wort dextrins into fermentable sugars to control beer body and alcohol content.
• Analytical Biochemistry: Used as a diagnostic tool for determining starch structure and quantifying amylose content.
• Textile Desizing: Removal of starch-based sizing agents from fabrics in an eco-friendly manner.
• Biofuel Production: Assists in the enzymatic hydrolysis of starch feedstocks for bioethanol manufacturing.
• Baking Industry: Modifies dough rheology and improves bread crumb texture and shelf life.
• Research & Development: A critical reagent for enzymatic studies, carbohydrate chemistry, and metabolic pathway analysis.
