Description

Maltohydrolase, Glucan 1,4-.Alpha.- is a specialized enzyme that catalyzes the hydrolysis of α-1,4-glucosidic linkages in starch and related polysaccharides. This precise catalytic action is critical for controlling the molecular weight and functional properties of carbohydrate polymers in advanced industrial processes. It is an essential biocatalyst for manufacturers in the food ingredient, pharmaceutical excipient, and biofuel research sectors seeking to engineer specific dextrose equivalent (DE) values and oligosaccharide profiles.

Application

• Starch Modification & Syrup Production: Used for the controlled hydrolysis of starch to produce maltose syrups, high-maltose corn syrups (HMCS), and other specific sugar profiles with defined sweetness and functional properties.
• Brewing & Fermentation: Acts as a mash enzyme to enhance fermentable sugar yield from adjuncts, improving fermentation efficiency and beer characteristics.
• Baking & Flour Improvement: Modifies starch in dough systems to improve crumb softness, shelf-life, and volume by generating specific sugars for yeast fermentation.
• Prebiotic & Functional Food Ingredient Synthesis: Employed in the enzymatic synthesis of isomalto-oligosaccharides (IMOs) and other non-digestible oligosaccharides used as prebiotic dietary fibers.
• Pharmaceutical Excipient Processing: Used in the production of tailored maltodextrins and cyclodextrins which serve as carriers, stabilizers, or solubilizing agents in drug formulations.
• Diagnostic & Analytical Reagents: Serves as a specific enzyme in diagnostic kits and biochemical assays for the quantitative determination of starch or glycogen.
• Biofuel Research: Investigated in enzymatic saccharification processes for breaking down starch-based biomass into fermentable sugars for bioethanol production.
